Information: A Precondition for Action

Written by

Production entails human activities that result in material, energy, information or other entities that are useful to individuals and to society; its development depends upon the collection, processing, dissemination and use of information. Work may be described as human activity directed to pre-set goals in the production process, with tools and equipment serving as the material instrumentality of such activity. But it should be borne in mind that in the work process the information that is continually received and organized affects and directs the process.

The work process itself contains information in the form of accumulated experience which is stored by the worker (as knowledge and skills); embodied, as it were, in tools, equipment, machinery and, in particular, by complex technological systems; and made explicit through the medium of information processing equipment. The work process is a concrete and dynamic way of using information to achieve certain set objectives. The safety components of this information are equally distributed among the various elements of work—the worker, the tools and equipment, the working environment and the objects of production; indeed, safety information should ideally be an integral part of the information needed for the production itself: instead of “how to produce something” it should be “how to safely (with lower risk) produce something”. Several experiments have demonstrated that information linking safety to production is not merely necessary but is increasingly being perceived as such.

Production entails not only the obvious technical creation of new output out of either natural raw materials or pre-existing man-made materials and goods, but also includes the modification and reorganization of information that pertains to the material production process and to the information cycle itself. The scope of the information element of a developing production process increases rapidly. Following the familiar practice of dividing the process of production into three parts, namely, energy production, materials production and information production, we may also divide its products into similar categories. However, these are usually of a mixed character. Energy is generally carried by matter, and information is either associated with matter—printed matter, for instance—or with energy, such as electrical charge or the optical and electronic impulses carried by fibre-optic lines. But, unlike material products, information does not necessarily lose its value when it undergoes reproductive processes. It is a product which can be reproduced in mass, yet its copies can be exactly as valid as the original.

Safety Information and Its Use in Production Systems

Safety information ranges over a great breadth of subjects and may assume a correspondingly great variety of forms. It can be classified as to whether it conveys statistical figures, descriptive information, reference data, original texts or quantitative or qualitative matter. It may be a statistical table setting forth a collection of quantitative data relating to accident incidence, or a chemical safety data sheet. It may be a computer-readable database, ready-to-use materials (including illustrations and drawings), model legislation and regulations, or the research results pertaining to a particular safety problem. Historically, most information needs were covered by conventional communication methods, oral and written, until the relatively recent advent of photography, radio communication, films, television and video productions. Although the methods of mass media were to facilitate electronic copying, they nevertheless lacked selectivity. Plainly, not all people need or are interested in the same type of safety information. Libraries and, in particular, specialized safety documentation centres provide a fairly comprehensive selection of documents which could provide specific details for each user of information, but their resources are not readily accessible in the form of copied matter. The latest methods of information collection, storage and retrieval, however, have solved this problem. Electronically managed information may contain the same amount of or more information than a full specialized library and it can be easily and quickly duplicated.

Safety professionals, namely, inspectors, industrial hygienists, safety engineers, safety representatives, managers, supervisors, researchers, and workers as well, will make use of information to the greatest desirable extent only if it is easily available. All that they need should be accessible right on their desks or bookshelves. Existing documentation could be converted into electronic form and organized in such a way that retrieval will be quick and reliable. These tasks are already being carried out and represent an enormous undertaking. First, selection is essential. Information should be assembled and provided on a priority basis and the retrieval process should be convenient and reliable. These goals require better organization of databases and more intelligent software and hardware.

Quantitative Safety Information

Information in factual, quantitative form is essentially expressed as numerical figures. Quantitative measures may record nominal values, such as a given number of accidents; ordinal values that define priorities; or ratios, such as may describe the frequency of accidents relative to their severity. The chief problem is to define criteria for the effectiveness of safety practices and to find the best ways to measure them (Tarrants 1980). Another problem is to design forms of information that are effective in setting forth the nature of (and the need for) safety measures and that, at the same time, are understandable to all concerned—workers, for example, or users of chemicals and chemical equipment. It has been shown that safety information will influence behaviour, but that the change in behaviour is influenced not only by the content of the information, but also by the form in which it is presented, for example, by its attractiveness and intelligibility. If risks are not effectively presented and correctly understood and recognized, one cannot expect rational and safe behaviour on the part either of workers, managers, designers, suppliers or others concerned with safety.

Quantitative risk data are not, in general, well understood. There is broad public confusion about which are the greater hazards and which the lesser, because there exists no uniform measure of risk. One of the reasons for this state of affairs is that the public media do not emphasize continually occurring problems, even the more serious ones, but tend to highlight relatively rare and striking “shocking” news.

Another factor limiting the effectiveness of safety education is that processing complex quantitative risk information may exceed the cognitive abilities of individuals to the extent that they rely on heuristics, unsystematically absorbing the lessons of experience, to make safety-related tasks manageable. In general, low risks are overestimated and high risks underestimated (Viscusi 1987). This bias may be understood if we consider that without any information, all risks would be considered as equal. Every piece of information obtained through experience will then encourage a skewed risk perception, with the more frequent but less harmful incidents receiving more attention (and more cautiously avoided) than the rarer but graver accidents.

Qualitative Safety Information

While quantitative safety information, with its sharp focus on particular hazards, is needed to concentrate our efforts on essential safety problems, we need qualitative information, conveying its fund of relevant expertise, in order to find practical solutions (Takala 1992). By its nature this sort of information cannot be precise and quantitative but is heterogeneous and descriptive. It comprises such diverse sources as legal information, training materials, audiovisuals, labels, signs and symbols, chemical and technical safety data sheets, standards, codes of practices, textbooks, scientific periodical articles, dissertation theses, posters, newsletters and even leaflets. The variety of materials makes it quite difficult to classify and subsequently retrieve these materials when needed. But it can be done and has indeed been successfully carried out: the preparation of company-, branch-, industry- and even nation-wide hazard profiles represents a practical example of the provision of qualitative information in a systematic way that at the same time attaches quantitative measures to the relative importance of the problems in question.

Another key issue is that of intelligibility. Comprehension requires that information be presented in a way that will be understood by the end user. The improper use of language, whether that of everyday speech or special technical terminology (including jargon), can create perhaps the greatest barrier to the global dissemination of safety information. Texts must be conscientiously and deliberately framed so as to make a strongly positive appeal to their intended audience.

It would be desirable to establish a comprehensive knowledge base of all accumulated safety and health information, accessible to users through interfaces tailored specially to each user group. Ideally, such interfaces would translate the desired elements of this information, without redundancy, into a format understood by the user, whether it should involve natural language, specified terminology (or absence of it), images, illustrations, drawings or sound, and would be adapted to the needs and abilities of the end user.

Impact, Presentation and Types of Safety Information

Company-level safety information and the information cycle

Studies of safety information systems within companies suggest that information flow within enterprises follows a cyclical pattern:

data collection →

data analysis and storage →

distribution of safety information →

developing preventive measures →

production of goods and materials (risks and accidents) →

data collection, etc.

The main methods used to collect data are accident investigations, safety inspections by enterprise personnel and the reporting of near-accidents. These methods concentrate on safety problems and do not pay much attention to health and industrial hygiene problems. They do not provide information on experience accumulated outside the enterprise either. It is essential to share such experience from elsewhere, since accidents are rare events and it is not likely that a sufficient number of similar incidents, especially major accidents (e.g., the disasters at Bhopal, Flixborough, Seveso and Mexico City), will occur in any one enterprise, or even in any one country, to serve as a basis for effective preventive efforts. They might, however, re-occur somewhere in the world (ILO 1988).

Safety-related activities that industry may undertake can assume a variety of forms. Information campaigns aimed at improving safety information dissemination may include safety slogans, development of a housekeeping index, positive reinforcement and training programmes for workers (Saarela 1991). In some countries, occupational health services have been established to involve health personnel in the company’s work of accident prevention. These services must have the capability to collect workplace information—to carry out job load and hazard analyses, for instance—in order to perform their everyday tasks. Further, many companies have established computerized systems for the recording and reporting of accidents. Similar systems, adapted to record accidents at workplaces according to a standard format required by workmen’s compensation bodies, have been established in several countries.

National and global safety information and theinformation cycle

Just as the safety information cycle exists within a company, there is a similar information cycle on a national, and international, level. The flow of safety information from nation to nation may be understood as a circle representing various phases in the movement of information where safety information may be either needed, processed or disseminated.

In order to assess the relative merits of various information systems, it is useful to discuss the dissemination of information in terms of the “information cycle”. The flow of safety information internationally is represented schematically in figure 1, based on Robert’s model (Robert 1983; Takala 1993). As a first step, safety information is identified or described by the author of a document, where the word “document” is used in its broadest sense, and may denote indifferently a scientific article, textbook, statistical report, piece of legislation, audiovisual training material, chemical safety data sheet or even a floppy disc or an entire database. Whatever its type, however, information may enter the cycle in either electronic or printed form.

Figure 1. The information cycle

MISSING

  1. Information is sent to a publisher or editor, who will evaluate its validity for publication. The publication of a document is, plainly, an important factor in its usefulness and general accessibility simply because unpublished materials are difficult to locate.
  2. Published documents can be used directly by a safety professional or they may target a non-professional end-user such as the worker at the workplace (for example, chemical safety data sheets).
  3. The document may then be sent to an information centre. In the case of documents that convey primary information (results of original research, for example), the centre will systematically collect, screen and select whatever useful information they may contain, thus carrying out the first rough reading of large volumes of documents. A regularly published or updated secondary publication, such as a periodical or database containing abstracts or reviews, may be published or made available by the information centre. This will draw attention on a continuous basis to significant developments in occupational safety and health.
  4. Such secondary publications or databases target mainly safety professionals. Examples of such secondary databases and publications are the CISDOC database and the Safety and Health at Work bulletin from the International Labour Organization, and the NIOSHTIC database from the National Institute for Occupational Safety and Health (NIOSH) in the United States. The interchange vehicle between a given institutional entity (e.g., a company) and the national or global information cycle is in all cases the user. The user is not necessarily an individual safety professional, but may also be the institution’s safety management system. A user of published material may furthermore communicate feedback directly to the author or publisher, a practice common for scientific publications.
  5. At this point in the information cycle, the published document may be modified as a result of “reality testing”, the stage at which the safety professional puts the information to actual use in order to reduce the number of accidents or work-related diseases, or to solve other problems at work.
  6. Experience contributes to better anticipation of health hazards and accidents.
  7. Experience may result in new research findings in the form of reports and documents which are sent to the publisher: thus the cycle is completed.

 

Applications of safety information

Information may be used for a number of purposes: training within and outside the company; design of machinery, processes, materials and methods; inspection and control operations. The varied character of such uses implies that the information must be prepared in a suitable form for each type of user. Users themselves modify and reprocess the information into new information products. For example, an inspectorate may draft new rules and regulations, machine manufacturers may set new guidelines in the light of their involvement in safety standardization activities, producers of chemicals may compile their own Material Safety Data Sheets and labels, and trainers may produce manuals, audiovisuals and handouts. Some information may be of a specific, ready-to-use type that offers direct solutions to individual safety and health problems, while other pieces of information may set forth improvements in the production process, such as a safer method, machine or material. Despite their variety, the common element among all of these information products is that in order to be useful, in the end they will have to be employed by a company safety management system. Resources involving processes, materials and methods must be selected, purchased, transported and installed; people to use them selected and trained; follow-up and supervision exercised; and outputs must be distributed with steady attention to a wide range of information needs.

Computerized Safety Information Systems

Computers are the latest link in the developmental process that ranges over all the information media, from spoken and written language to contemporary electronic systems. In fact, they may be able to do the work of all of the preceding types of information manipulation. Computers are particularly suitable for this purpose because of their ability to handle highly specific tasks involving large volumes of information. In the field of safety information, they may be especially useful for the types of need listed in figure 2.

Finding and Using Information

Written by

As the fund of accumulated knowledge relating to safety and health grows and is publicized by general and specialized media alike, concerns having to do with personal health in general, with environmental hazards and with occupational safety and health have been receiving increasing attention. Especially with respect to the workplace, the principle that both employers and employees have a need and a right to be supplied with adequate safety and health information is becoming more and more clearly recognized and actively implemented.

Need for Information

Reliable, comprehensive, and intelligible information is essential to the securing of occupational safety and health (OSH) objectives. This information must be conveniently accessible, up-to-date, and directly applicable to the specific circumstances of the user. But the great variety of work settings and the enormous volume and diversity of OSH information, whether touching upon toxicology, biochemistry, behavioural science or engineering, challenge the providers of such information to attend to such needs as the following:

  • academic or theoretical information, required by sophisticated technical or scientific specialists and researchers
  • practical information, required by regulators, employers and employees
  • legislative information, required for developing and implementing policies, training employees and employers, developing and implementing OSH programmes and complying with OSH requirements. The responsibilities of safety professionals and of representatives and committee members assigned to safety-related duties normally include providing information to others. Furthermore, in many countries safety and health laws require information: (a) to be provided to workers by governments, employers, and chemical suppliers, among others; and (b) to be generated by organizations such as the companies to which the laws apply.

 

Occupational safety and health information is needed in order:

  • To make informed decisions. Occupational safety and health information enables regulators, legislators, OSH professionals, labour and industrial organizations, employers and workers to make sound decisions concerning a healthy and safe work environment. These decisions can include the development and implementation of occupational safety and health policies, regulatory requirements, and safety and health programmes appropriate for the workplace.
  • To safely discharge duties. Workers need occupational safety and health information in order to take day-to-day decisions regarding the effective yet safe performance of their duties. Employers require it in order to train their employees to take these decisions.
  • To meet legislative and regulatory requirements. Without complete and accurate occupational safety and health information, workers, employers, labour organizations and occupational safety and health professionals would be unable to meet these mandates.
  • To exercise rights. Increasing numbers of workers have been accorded the right to know about the hazards involved in their duties and to participate in decision-making regarding their work environment. In some countries, they have the right to refuse dangerous work.

 

Effective Information Dissemination

The following considerations need to be addressed in order to ensure that a dissemination programme for occupational safety and health information will be effective.

  1. The information must be presented in a form that is suited to the needs, circumstances and background of the end-user. For example, documents containing technical information may be more useful to occupational safety and health professionals than to those employees and employers who usually are less familiar with technical language. However, consideration should always be given to converting technical material into lay language in order to effect a comprehensive occupational safety and health information programme. To be effective, occupational safety and health information must be useful and understandable.
  2. Alternative audiences should be considered. For example, an article on hazards in commercial restaurants should be of interest to schools, prisons and other institutions that have dining facilities.
  3. Information must reach the people who need it, and a comprehensive strategy should be developed to communicate it to them. Available methods include direct mail to individuals on a purchased or developed mailing list; presentations at seminars, symposiums and training courses; exhibits at professional conferences as well as at meetings of workers and small businesses; and advertisements in trade and professional periodicals.
  4. Frequently, secondary disseminators can be used to augment a dissemination strategy. These cooperative endeavours encourage consistency, reduce duplication and benefit from the secondary disseminators’ strengths. For example, after serving as a document reviewer, a trade association representative may be interested in making an employee-related publication available to the membership or, minimally, advising the members of the original document’s availability. Secondary disseminators can also reduce costs because they may be willing to reprint the material for those who may need it, particularly if they are loaned the camera copy or negatives.

User Population

Occupational safety and health encompasses the full spectrum of work activities and occupations. Information on safety and health relating to these activities is needed by people who have responsibility under the law for ensuring safe and healthy working environments or who may be detrimentally affected by hazards originating—even remotely—in work activities. These include: people  who  are  directly  involved  with  hazards  at  work  or who are engaged professionally in occupational safety and health; people from other organizations that provide services to a workplace; and communities and the general public who may be exposed, perhaps at a greater remove, to any deleterious effects of work processes. Consequently, the user profile for occupational safety and health information covers an extremely broad range of types.

First, there is the decision maker. In every establishment, several categories of people occupy key decision-making positions that directly (and, often enough, indirectly) affect the health and well-being of people associated with the particular workplace, those in the surrounding communities and others who may be affected by the establishment’s practices. These people may be employers, senior line managers, members of joint safety and health committees, safety and health representatives or specialist staff responsible for safety and health, purchasing, training and information management. All of these categories of people need adequate information in order to carry out their safety-related functions effectively and to take informed decisions concerning OSH problems and how to deal with them.

Employees themselves are by no means exempt from the need to acquire and act upon OSH information. All employees, whether self-employed, working in any other part of the private sector or for a government establishment, regardless of country, location, industry or role, have a responsibility towards safety and health that is associated with their work and that requires information according to their particular circumstances. All need to know what present or potential hazards they may be exposed to and to be familiar with possible solutions and preventive measures, what their rights and responsibilities are and what resources they have at their disposal that can help them carry out their duties in this connection.

In the field of safety and health itself, managers who are specifically responsible for safety and health in the workplace and practitioners in occupational safety and health and related fields—nurses and physicians (whether in-house or on-call), safety educators, safety inspectors and others whose expertise comprises workplace safety, health and hygiene—are constantly in need of information on various occupational safety and health concerns to carry out their daily responsibilities.

Although many people and organizations are in contact with workplaces only through the services they provide, it should be borne in mind that they may have a safety-related impact on the workplaces they serve and, in turn, may be affected by their contact with these environments. The suppliers of equipment, materials and chemicals to such consumers as factories and offices, industry associations, trade unions, transport services, inspection services or worker health services, must make it their concern to examine whether their mutual relationship may imply any potential for the development of unsuspected safety problems and in order to do so, they need information concerning the specific circumstances associated with providing their services to the various workplaces.

Academics and researchers working in subject areas associated with workplace safety and health are heavy users of information on those subjects, including review materials and reports of current and past research. Technical and scientific information is also needed by professionals in fields such as engineering, chemistry, medicine and information management itself. In addition, for purposes of reporting on specific events or concerns, professionals in the public media must seek background information on OSH topics so that they may in turn inform the general public.

Another category of OSH information users are governments at all levels—local, regional and national. Policy makers and legislators and regulators, planners and other bureaucrats all deal with occupational safety and health issues that bear upon their particular functions.

On perhaps the largest scale of information need and use as far as breadth of dissemination is concerned, there is society itself. Environmental and health concerns and greater recognition of citizens’ rights, together with the impact of modern means of communication, have heightened society’s awareness of occupational safety and health issues and created a vast demand for information so that society as a whole is now making increasing—and large—demands for information on various occupational safety and health concerns. Consumers, communities in proximity to work establishments and the public in general are concerned about the activities that are carried out in workplaces and about the products they produce, and want to know about their safety and health implications. In particular, citizens’ groups and lobbyists concerned about the safety and health of communities want information on all aspects of hazards related to workplace activities such as production, emissions to the environment, transportation and waste disposal that are relevant to their cause.

There are enormous complexities in informing this diverse spectrum of information users who represent different backgrounds, education levels, cultures, languages and levels of knowledge of OSH (not to mention work environments). In order to be effective, the content, presentation and accessibility of the information must be targeted to meet the specific needs of these various categories of user.

[V. Morgan and P.K. Abeytunga]

Nature of Safety and Health Information

Quality of information

OSH information needs to be authoritative and, more important, validated by experts. Authoritative information comes from official and recognized sources or organizations, but one must be aware that information from other sources, which does not appear to have been validated, is increasingly being produced. Some examples of errors due to lack of validation are:

  • Measurements are not checked and appear with the wrong abbreviations (e.g., “m” (meaning metres) instead of “mm” (meaning millimetres).
  • The decimal point is in the wrong place in an exposure limit.
  • The wrong chemical name is used.
  • Illustrations show incorrect safety and health practices.

 

Problems with occupational safety and health information

Although there is an overwhelming amount of occupational safety and health information, there are areas where the information is sparse or not collected in an accessible format. The necessary information is fragmented among various subject areas and sources, many information sources are biased and information is often not available or not in a usable form for the many people who need it. To save the information seeker time the following points should be noted.

Legislation: All legislation on occupational safety and health is available but there is not, as yet, a central database of legislation from all countries. The International Occupational Safety and Health Information Centre (CIS), headquartered at the International Labour Office (ILO), has made some efforts in this area, but CISDOC, the CIS database, is not fully comprehensive. In the United Kingdom, the University of Salford European Occupational Safety and Health Law Unit has a complete up-to-date collection of the full text of the occupational safety and health legislation of the European Union Member States including the European Directives in place in each country. This collection is widening to include the Scandinavian countries and ultimately the rest of the world. The UK Safety and Health Executive Information Service headquarters in Sheffield also has a complete set of the full text of the legislation of the European Union Member States, but it is correct only up to 1991. There are a number of databases available giving reference to legislation of different countries and also some printed updating services available in different countries.

Statistics: Most countries do not have a uniform or consistent way of collecting statistics. Therefore, it cannot be assumed that any two countries use the same methodology; consequently data from different countries cannot easily be used for comparative studies.

Ergonomics: While many databases include information on ergonomics no one database exists which brings together information available from world-wide sources. A useful printed abstracting journal  is  Ergonomics  Abstracts which  is  available  in  CD-ROM format.

Research: There is no comprehensive source of information on international research on subjects on occupational safety and health, but there are numerous journals and databases containing the results of research and research programmes. The Institut National de Recherche et de Sécurité pour la Prevention des Accidents du Travail et des Maladies Professionnels (INRS) in France has a database but it does not contain all known occupational safety and health research.

Films and videos: Films and videos help to convey information in an easy and understandable way, but there is no comprehensive database of films and videos, although new titles appear in a neverending stream. CIS has attempted to collect information on the available material in the CISDOC database, as does the UK Safety and Health Executive Information Services in the HSELINE database. Some countries, such as the UK, the US and France, produce annual catalogues which contain new titles published the previous year.

Other considerations: Because of these problems and gaps the information seeker on occupational safety and health will not find a single complete source for answers to questions. There are a number of subject areas and disciplines involved which must be checked to obtain a full picture of any of these topics.

The information user should be aware that there can be a lack of knowledge on a particular topic, or even conflicting or biased opinions, and it is wise to obtain interpretations from specialists before reaching conclusions. Some information can be easily and quickly transferred in today’s world but consideration must be given to the local conditions and also the legal requirements of the country.

Cost of Information

While many large organizations which may be government based are willing to share information at no cost or very low cost, the seeker for information on occupational health and safety must be aware that the cost of good validated information is constantly rising as authoring, production, printing and distribution costs for both printed paper and electronic products continue to rise.

Therefore a cost-effective information service which has not only up-to-date information but also high quality, trained and qualified information professionals with relevant experience is becoming a rarity. Organizations such as the International Labour Organization with its increasing number of member countries are encouraging the setting-up of focal information centres or resources where the information seeker can use and also gain access to other worldwide centres. Improved direct telecommunications should increase the capacity for supporting regional centres.

Because prices change all the time, it did not seem appropriate to include them in the following section. However, the relative costs of documents will always depend on the amount of effort needed to assemble their contents, the number of copies printed and the extent to which the cost of buying a document will be offset by the benefit of applying its contents, although the price of high quality publications may be reduced by public subsidy.

[S. Pantry]

Types of Safety and Health Information and Where to Find Them

The range of users described above defines the range of document types that constitute “occupational safety and health information”. It is helpful to distinguish between those documents that deal exclusively with occupational safety and health issues (“core" publications) and those (“others”) that contain useful information but have a different focus. The number of publications presented in table 1 has been limited by space considerations. The journals listed have been chosen because of the frequency with which they have been cited in other publications or in bibliographic databases. (Inclusion of a source should not be taken as an endorsement by the ILO and is no reflection on a publication or series that is not named.)

Traditional paper sources

The most common vehicle for information is paper, in the form of books and periodicals. These periodicals appear regularly and the books have extensive, well-established distribution networks. The primary literature is the set of journals where new observations, discoveries or inventions are reported by the persons responsible. State-of-the-art reviews also appear in primary publications. To be published in a primary publication, an article must be reviewed by a number of experts in the given field, who ensure that it reflects good practice and that its conclusions follow from the facts presented. This process is called peer review.

Typical of the “other” category are among others, the Journal of the International Institute of Noise Control Engineering and the Journal of the American Medical Association (JAMA). Government agencies in many countries print statistical periodicals that count as primary literature, even though they do not use the peer review process of the research journalists. The Morbidity and Mortality Weekly Report issued by the Centers for Disease Control and Prevention in the US is one example. Primary serials can be found in the libraries of the relevant institutions ( the JAMA in medical school and hospital libraries, for example).

There are some core mass-circulation magazines that are not peer reviewed, but that do provide primary information in the form of news of recent or upcoming events, in addition to easy-to-read articles on topics of current interest. They often include advertisements for occupational safety and health products and services that are themselves useful information on sources of supply. They may be published by public authorities—for example, Australia Newsletter and Bezopasnost’ truda v promyshlennosti (Russia), by private non-profit safety councils—Australian Safety News, Safety and Health (USA), Promosafe (Belgium), Safety Management (UK), Arbetsmiljö (Sweden), SNOP (Italy) or by private enterprises—Occupational Safety and Health Letter (USA). There are also many publications in other specialities that include useful and interesting information—Chemical Week, Plant Engineer, Fire Prevention.

The difficulty in finding information on one particular topic in the mass of the primary literature has prompted the development of secondary sources. These are guides to the literature or to recent events, such as court cases, whose official write-ups appear elsewhere. They indicate where a given document on a topic is published and usually give a brief summary of its contents. There are also citation indexes, which list the publications that cite a given document; these permit efficient retrieval of relevant publications once one key reference has been identified (unfortunately, there is none devoted exclusively to occupational safety and health). Because they must be up to date, secondary sources use the latest electronic technology to speed their publication.

In order to improve access, particularly to areas with a limited number of computers, some databases are also made available in printed form. The ILO’s Safety and Health at Work—ILO/CIS bulletin is a printed version of CISDOC which is issued six times a year and includes annual and 5-year indexes. Similarly, Excerpta Medica is available as a journal. Some secondary source databases are also available on microfiche, such as RTECS, although it is more common that the paper-based bibliographic information is supported by full-text microfiche. In these cases the database is in two parts: bibliographic references and abstracts on paper (or in electronic format) and the full text on microfiche.

Some other titles of secondary sources are Occupational Health and Industrial Medicine, and CA Selects “Occupational Safety and Health”. Others include the Science Citation Index, Social Science Citation Index, Chemical Abstracts, and BIOSIS. Because of the number of highly trained people involved in their preparation, secondary sources tend to be expensive.

Some newsletters are valuable secondary sources, as they cite important recent publications, laws or court decisions. Examples include: Core publications: OSHA Compliance Advisor (USA); Other: Chemicals in Progress Bulletin (US EPA). Whereas many government publications of this type are free, the privately researched and compiled newsletters tend to be expensive. They are rarely found in libraries; those who need them may find them worth the price of subscription.

A third major type of information source includes textbooks, encyclopaedias and compendia. Whereas reviews in the primary literature describe a domain of knowledge at the time of their writing, tertiary-source reviews recount the evolution of that knowledge and its larger context. Compendia of data bring together values originally measured and reported at different times over many years.

Core publications in this “tertiary category” include Patty’s Industrial Hygiene and Toxicology (Patty 1978), Reactive Chemical Hazards (Bretherick 1979), Dangerous Properties of Industrial Materials (Sax 1989), Handbuch der gefährlichen Güter (Hommel 1987), The Diseases of Occupations (Hunter 1978), and this Encyclopaedia. Examples of tertiary publications in the “other” category are the McGraw-Hill one-volume encyclopaedias that cover various areas of science and technology and the Kirk-Othmer Concise Encyclopedia of Chemical Technology (Grayson and Eckroth 1985), 4th edition in 27 volumes (volumes 1 to 5 are published). Readers should not overlook the large quantity of occupational safety- and health-related information to be found in the large general encyclopaedias: Britannica, Universalis, Brockhaus, etc.

Grey literature

There are many books and periodicals that do not have the same highly organized system of publication and distribution as the traditional paper literature, for example reports, data sheets and catalogues; these are referred to as grey literature because they are hard to find. Primary literature in the grey category includes government agency reports (research reports, statistics, accident investigations, etc.), theses and reports from university and commercial research institutes, such as the State Research Institute (VTT) in Finland or the European Chemical Industry Ecology-Toxicology Research Centre (ECETOC) in Belgium. A good source of information on occupational safety and health in developing countries can be found in reports of public and private agencies. Manufacturers’ catalogues can provide a wealth of information. Many exist in more than one language, so that a full set provides a guide to a kind of terminology that is rarely found in dictionaries.

To help the occupational safety and health professional find these irregularly published documents, a number of secondary sources have been created. They include government reports, announcements, index journals and dissertation abstracts. The publishers of reports may occasionally include a catalogue of previously published documents in the reports series itself. The secondary sources are not grey literature: they are published regularly and are easy to find in libraries.

A major type of grey literature is tertiary: Material Safety Data Sheets (MSDS) and criteria documents. (Some data sheets are periodicals; e.g., the Industrial Safety Data File, published monthly by Wilmington Publishers in the UK). Core sources are: national authorities (NIOSH, Arbetsmiljöinstitutet), international programmes such as the International Programme on Chemical Safety (IPCS), manufacturers´ product (MSDSs).

Laws, standards and patents in print

Most countries and regional groupings (for example, the European Union) have as a primary source an official gazette where new laws, derived regulations and patents are printed. Offprints of individual laws, patents, etc., are also issued by government printers. Standards are a more complicated case. Technical standards are frequently developed by officially recognized voluntary associations such as the American Society for Testing and Materials (ASTM) or independent government-chartered institutes (such as the German Deutsche Industrie Normen (DIN)); these bodies cover their operating costs from the sale of copies of their standards. Health and welfare standards (such as limits on working hours or on exposure to certain substances) are more often set by government agencies, so the texts appear in official journals.

The American Association of Law Libraries has begun to publish Foreign Law: Current Sources of Codes and Legislation in Jurisdictions of the World. Two of the projected three volumes have appeared (The Western Hemisphere, 1989 and Western and Eastern Europe and the European Communities, 1991). The looseleaf volumes are updated annually. This work describes the legal systems of all the Member States of the United Nations and of those dependencies that have their own legal regimes. It identifies the relevant texts under various subject headings (occupational safety and health texts are found under “labour” and industrial sector headings). The editors note numerous other secondary sources, and include a list of foreign legal publications vendors.

The compendium is the normal tool for work with laws and derived regulations—the time lag between publication of a new law in the official gazette and its inclusion in collections is generally very short, and the text may only have meaning in the context of other regulations. With standards, too, it is frequently the case that an individual standard (say, the International Electrochemical Standard (IEC) 335-2-28 on sewing machines) does not state all the applicable requirements, but cites a “parent” standard in the same series that states universal requirements (IEC 335-1, Safety of household and similar electrical appliances). Many countries have consolidated editions of their labour codes in which the central occupational safety and health legislation can be found. Similarly, the ILO and the International Organization for Standardization (ISO) publish collections of standards, while the International Register of Potentially Toxic Chemicals (IRPTC) Legal File contains information from thirteen countries.

Information in Electronic Form

The study of occupational safety and health practices and the disciplines that support them grew vigorously from 1950 to 1990. Organizing and indexing the resulting mass of publications was one of the earliest applications of computers.

Databases

As of 1996, only a few full-text databases devoted exclusively to occupational safety and health exist but the number is growing rapidly. Relevant information, however, can be found in others, such as on-line databases of the American Chemical Society Journals Online and the Dow-Jones and other news services. On the other hand, there are many secondary sources in occupational safety and health available online: CISDOC, NIOSHTIC, HSELINE, INRS, CSNB, and parts of HEALSAFE. Other sources include ERIC (Educational Resources Information Center), which is a US service; MEDLINE, which includes abstracts of the world medical literature prepared by the United States National Library of Medicine; NTIS, which indexes US “grey literature”; and SIGLE, which does the same for Europe.

Different types of existing database on occupational safety and health include the following:

  • Bibliographic databases. These are databases of already published documents, where one entry (record) may include such items (fields) as author name, title of document, name of publisher or source, and location of document and its abstract. The records generally include classification indicators which are primary or secondary descriptors or keywords describing the record. Keywords are often taken from a controlled vocabulary, or thesaurus. The document itself is not stored in the database.
  • Full-text databases. Unlike the bibliographic database, which contains only bibliographic information and perhaps an abstract, all relevant text (the full text) of the document is included in this kind of database. There are usually some classifiers and descriptors as well, to help in retrieval. Databases on chemical safety data sheets, each containing one to ten pages, and even entire encyclopaedias and other large documents, may be kept in such a format. Full-text databases correspond to primary and tertiary sources of printed information—they are collections of facts and full sets of data—whereas bibliographic databases are secondary sources which describe or refer to other documents. Like secondary sources in print, they may contain abstracts of the cited information.
  • Factual databases. These contain measures or numerical values, such as threshold limit values of chemical substances.
  • Multimedia databases. These hold pictures, drawings, illustrations, sound and video (or references and links to it) as well as the text of the document (Abeytunga and de Jonge 1992).
  • Mixed databases. Elements of each of the databases described above are included in a mixed database.

 

Any of these databases allows a person with a question to be answered to gain access to the relevant electronic information in two ways: by using telephone lines connected to a computer where the information is stored, or by acquiring a diskette or compact disc containing the information and installing it on the user’s personal computer.

On-line services

Large safety databases that can be accessed through large computers and are always accessible whenever the computers are running are called on-line databases. The organizations that run on-line systems are referred to as their hosts (Takala et al. 1992). Until recently, on-line databases have been the only feasible means for the storage and dissemination of information via magnetic media that allows the use of computers and specially designed search software for the retrieval and downloading of data (Wood, Philipp, and Colley 1988). Practically anybody who has access to a video display (or microcomputer) terminal and telecommunication (data or telephone) line may make use of an on-line database.

With the proliferation of commercially available on-line services since the early 1970s, information has become more easily accessible. It has been estimated that as of 1997 there were well over 6,000 databases available for information retrieval in the world, covering many subjects and totalling over 100 million references. In addition, there are over 3,000 CD-ROM sources, including an ever-increasing number of full-text CD-ROMs.

On-line services, which started with bibliographic databases, rely on huge central mainframe computers which are costly to establish and maintain. As the volume of information and user population grows, the upgrading of the systems alone involves heavy investments.

Open systems, which allow computers to talk to computers anywhere in the world, are increasingly becoming a standard feature of the workplace environment, eliminating the need to host all the necessary safety data on an “in-house” computer.

Telecommunication problems and the limited number of terminals available in developing countries restrict services such as these, mostly to the industrialized world. The level of existing infrastructure; political concerns such as security, secrecy and centralization; and cultural peculiarities may severely restrict the use of on-line services. In addition, the complexity of the access and search systems further limits the number of users. Those who are only occasionally interested in the information will most likely be insufficiently skilled in the necessary techniques, or may perhaps forget the correct procedures entirely. Consequently, it is trained information specialists who tend most often to use these computerized systems. Safety professionals, particularly at the factory level, rarely use them. On-line databases are not much used for safety training purposes because of expensive, by-the-minute, user charges. On-line databases are, however, irreplaceable when the database size is so great that a CD-ROM or even several of them cannot accommodate all the desired data.

Guides to on-line searching

There are a number of useful published guides to on-line searching and databases which the OHS information seeker may wish to consult. A public or university library and information service may supply them or they may be purchased from the publisher.

Large hosts keep hundreds of different databases available 24 hours a day. In running an on-line search, various search strategies combining a number of technical requirements can be carried out. Using special searching techniques such as descriptor or keyword searching, one can range over a large amount of available materials, concentrating on the information most relevant to one’s needs. In addition to search by keyword, freetext searching, in which a search is made for specified words located in almost any field of the database text, can provide further information. Practically no limitations exist as to the size of a database, and several large databases may be put together to form a cluster. A cluster can be used as if it were a single database, so that one search strategy can be applied to all or to selected databases simultaneously. This type  of  All  Safety database  is  currently  being  set  up  by  one of the large hosts, the European Space Agency’s Information Retrieval System (ESA-IRS). This cluster is intended to include many large databases and its size is in the range of gigabytes, or billions of characters. Such clusters are, of course, completely computer-dependent.

Full lists of available on-line databases may be obtained from the major international hosts, namely, ESA-IRS, DIALOG, ORBIT, STN, CCINFOline and Questel. Each host identifies only its own databases; more extensive listings can be found in directories like Gale Research’s Directory of Databases (including CD-ROMs and diskettes), which is available on-line on ORBIT and Questel as well as in print.

Several compact discs offer databases devoted to occupational safety and health: the OSHA CD-ROM from the United States Occupational Safety and Health Administration (OSHA), the CCINFO discs of the Canadian Centre for Occupational Health and Safety (CCOHS) in English and in French (CCOHS 1996), the UK’s Health and Safety Executive Information Service full text CD-ROMs OSH-CD and OSH-OFFSHORE, published by SilverPlatter, which also publishes many other occupational safety and health related CD-ROMs such as CHEMBANK, EINECS, TOXLINE, and EXCERPTA MEDICA. Springer-Verlag also publish GEFAHRGUT, a CD-ROM in German. The full text of ILO Conventions and Recommendations relating to occupational safety and health can be found on ILOLEX, a CD-ROM published by Kluwer. Secondary information can also be found in the CCINFOdiscs as well as on the OSH-ROM from SilverPlatter. MEDLINE and PESTBANK are two further CD-ROMs of interest.

Many kinds of useful information sources can be obtained in this way on diskette. GLOVES lists properties of the materials used for protective gloves to help users choose the most resistant ones for a given job. Bretherick’s Reactive Chemical Hazards is available on diskette, as is an ILO collection of information on regulated workplace chemicals, exposure limits in 13 countries, risk and safety phrases to be used in labelling and citations of relevant publications.

Other diskette sources include UN-Earth, which supplies data on UN agencies, programmes and areas of competence. There exist, too, secondary guides to data. A core source is FACTS, containing abstracts of industrial accident reports held at the Dutch National Technical Institute (TNO). There are other programmes to assist the practitioner, for example, ACCUSAFE (a safety auditing system from the United States National Safety Council); EBE, an information management system developed by the CIS Regional Technical Co-operation Project for Asia.

Subject Specialists

Solving occupational safety and health problems is not simply a matter of amassing facts, someone has to use the facts to devise solutions. All occupational safety and health specialists have areas of expertise, and when problems lie outside one person’s competence it is time to call for help. Major industries often have dedicated safety and health operations, such as the Center for Chemical Process Safety of the American Institute of Chemical Engineers. Local poison control centres can help with product identification as well as workplace emergencies. Professional societies (e.g., The American Society for Testing and Materials) may publish registers of recognized experts. Specialist publications (e.g., Fire Prevention) include useful advertisements. In many countries, national agencies offer consultancy services.

Every library in the world is an information centre where the facts relevant to occupational safety and health can be found. However, not every possible question can be answered in any single library. In general, information specialists or reference librarians will know the specialized sources in their regions and can advise patrons appropriately. There are also printed guides, such as Gale Research Inc.’s Directory of Special Libraries and Information Centres (16th ed., 1993). The country-level institutions that serve as CIS National and Collaborating Centres form a network that can route requests for information to the most appropriate source of expertise.

Workplace Safety Information

Because these “publications”—posters, signs, brochures, etc.—are images rather than words or numbers, they have not been amenable to electronic storage and retrieval in the past. At the time of writing, that is changing, but the OSH specialist seeking appropriate leaflets to hand out at a half-day course in fire safety should probably turn to the local fire department before turning on a computer. Of the core OSH databases, only CISDOC systematically includes references to training materials, and the CISDOC collection is indicative rather than exhaustive.

As libraries do not normally stock catalogues, the interested individual must build up a personal collection by contacting suppliers. These include commercial firms (e.g., Lab Safety Supply International), national or government-chartered private agencies (insurers, unions). An initial set of addresses can be compiled from the source information in CISDOC.

Implications for Information Access

Search strategies

Searching for information can be very frustrating. The following advice is offered, especially to those who do not enjoy the benefits of a full-fledged information service or library onsite.

How to obtain a loan or photocopy of an article, book, or report

One may make use of a local public, college, polytechnic, university or hospital library. Many provide material for reference only, but have photocopiers onsite so that items may be reproduced (with attention to copyright conditions). First one should check the indexes or catalogues of the library: if the item sought is not in stock, the information specialist or librarian will indicate another library which may be able to help. The safety specialist in one’s trade union, professional association or employing institution may be approached for assistance. Any request should be framed as helpfully as possible, with attention to the information specialist’s or librarian’s need for the following sorts of information:

  • title and author(s) of article, book or report
  • publisher
  • year of publication
  • edition
  • International Standard Book Number (ISBN)—this is a unique identifier given to every document published
  • title of periodical or journal
  • date of periodical or journal and volume, part number and pages required
  • name of database.

 

It can take up to three weeks or more if an item has to be borrowed from another source, but it may be obtained more quickly if one is prepared to pay for a “premium” service.

How to search for information on a particular subject.

Again one should make use of local services and contacts. Information specialists or librarians will assist the information seeker in using the various traditional indexes and abstracts. Further information given in this chapter will be of use in any search, and one might check various bibliographies, yearbooks, guides, other encyclopaedias, dictionaries and books and write to relevant organizations for further information. Using established networks pays dividends. A local information specialist or local library should be able to carry out an on-line or CD-ROM search on one or more of the computerized databases listed in this chapter.

Search techniques

The information sought should be specified clearly; for example, “injuries” is too broad a term for seeking information on a subject like “low back pain problems among nurses”. Particular aspects of a subject should be defined accurately, with mention of whatever keywords, related terms, synonyms, chemical name(s) or chemical abstracts registry numbers, and so on, that may be available to the inquirer. The name of an author who is a known expert in an area of concern may be checked to find further, more recent publications under his or her name. One should decide how much information is needed—a few references or an exhaustive search. Information published in other languages should not be overlooked; the British Library Document Supply Centre (BLDSC) collects translations on all subjects. NIOSH in the United States, CCOHS in Canada and the Health and Safety Executive (HSE) in the United Kingdom have extensive translation programmes. The HSE deposits more than 700 translations with BLDSC each year.

It is useful to keep a standard search form (see table 2), at one’s disposal to ensure that each search is carried out systematically and consistently.

Technology advancement

Technology continues to advance rapidly, with such new developments as the worldwide delivery of high-bandwidth information at high-speed transmission speeds becoming more available at ever-lowering costs. The use of electronic mail is also making access to information easier, so that seeking guidance and advice from specialists around the world is becoming much simpler. The take-up and use of facsimile transmission of data have made a valuable contribution, again at low cost. The potential of these new informational technologies is enormous. Their facilities for accessing information at ever lower cost can increasingly help to reduce existing disparities in the availability of information between countries and between regions in a country. As the information delivery networks expand and further innovative applications are created using these beneficial technologies, more and more people will be reached, so that the role of information as a means of accomplishing desired changes in the workplace can be realized.

Cost benefit of technology

New technologies are also a boon to developing countries. It is well known that knowledge and information are vital to achieving improved quality of life and quality of the environment. Information technologies present one of the most cost-effective means for developing countries to keep pace with progress in various fields of activity. Electronic technologies may substantially enhance the ability of developing countries to achieve the benefits of improved information dissemination in a cost-effective manner.

Mainframes and on-line systems, while by no means obsolete, are costly for many institutions. Costs such as data production and telecommunications charges are high and often prohibitive. Today’s technologies, such as CD-ROM and Internet, are the best way for these countries to be informed and to come to terms with current knowledge in many areas, especially the very critical ones relating to health. The advantages that they offer for presenting large collections of information in forms that speak directly to the users and quickly and conveniently meet their diverse needs are undeniable.

Costs of an entire workstation—personal computer, CD-ROM reader and their applications—are falling rapidly. The affordability of PC-based information and the local skills in information technologies, provide developing countries with an opportunity to conduct activities on vital information at the same level as the developed world.

Information Management

Written by

Reliable, comprehensive and intelligible information is essential for occupational health and safety. Users of such information are managers, workers, occupational safety and health professionals, safety and health representatives and occupational safety and health committee members. The responsibilities of professionals, representatives and committee members normally include providing information to others. Occupational safety and health laws in many countries require information to be provided to workers by governments, employers and chemical suppliers, among others, and to be generated by organizations such as companies to which the laws apply.

Enterprise Level Information

Viewed from within an organization, the information needed for occupational safety and health is of two basic types:

Table 1. Information required in occupational health and safety

INF030T1

Externally generated information. This information is required within the organization to address specific needs and to solve problems. It is diverse and voluminous, and it comes from numerous sources (see table 1). To achieve the desired standards of reliability, comprehensiveness and intelligibility, it has to be managed. Information management involves three ongoing processes:

  1. analysing the information needs of the information users
  2. identifying and obtaining the information required
  3. supplying the information needed by the users.

 

Internally generated information. This information is used to help identify safety and health problems, to monitor performance and to comply with legal requirements.

Collecting, coding and storing information from accident investigations can help identify recurring accidents and highlight causal factors. For instance, records of individual workers’ exposure to particular chemicals may be important years later if questions of job-related disease arise.

Information is drawn from such data by analysis. For the analysis to yield reliable conclusions, the data must be comprehensive and trustworthy. To be trustworthy, the information must be collected and compiled according to scientific principles. For example, the question or problem should be set out clearly in advance so that all the appropriate data are collected, and that

  • The types of data to be included in the compilation are strictly defined.
  • Collection of the data is carried out in a consistent manner allowing for the checking of the data’s validity and integrity.
  • The limitations of the data are understood and stated.

 

Information management involves the processes of data collection, storage, retrieval and analysis.

Organization of Information Management

The tasks of information management are often organized and conducted by an information service. The functions of such a service include:

  1. Ensuring that essential and up-to-date information is available when it is needed, and that users are not overburdened with excessive or redundant information.
  2. Making the information usable for the people who need it. Doing so often requires detailed knowledge of the needs of the persons seeking the information, and in-depth understanding of the information they seek.
  3. Helping users to find information for themselves.
  4. Actively disseminating information. Access to information in occupational health and safety is a matter of general right, not a privilege for a select group. Desk-top publishing has reduced the cost of producing pamphlets, newsletters and other materials for wide distribution.
  5. Collecting and providing information in an efficient and cost-effective manner. No information service has an unlimited budget.
  6. Keeping abreast of legal responsibilities for collecting and providing information.
  7. Providing or coordinating the resources and expertise required for production and analysis of internally generated information, including:
  • company safety information systems (accident records, near-miss reporting)
  • accident and disease statistics, registers of exposures (see also the chapter Record Systems and Surveillance)
  • serious-accident investigation databases (see also the article “Audits, inspections and investigations”)
  • specific data collection surveys (see also the chapter Epidemiology and Statistics)
  • inspection recording systems and databases
  • lists and registries of experts, addresses
  • medical record databases (see also the chapters Occupational Health Services and Ethical Issues).
  • Facilitating surveys and research. Methods will often be drawn from scientific disciplines such as epidemiology and statistics. The information service can help the researchers to gather the background information they need, provide computer facilities to store data, and disseminate the results of the research throughout the occupational health and safety community. In some types of study, the information service may also participate in data collection.

 

For the information service to fulfil all these functions successfully, it must overcome various problems. One continuing problem is the high rate of growth in the already considerable quantity of information potentially relevant to occupational health and safety. This problem is compounded by the many updates and revisions of existing information. An extension of this problem is that the apparent surfeit of information conceals a lack of multidisciplinary material. Much of the information resulting from research in medicine and engineering, for example, is communicated to specialists. It may be unintelligible to anybody else. The new knowledge is then not transferable to some potential users for whom it may be of great importance. One role of an information service is to stimulate production of multidisciplinary materials.

Other problems arise because of barriers that potential users experience in accessing or using information. For example:

  • Human language. Much of the information available in occupational health and safety is framed in a language that many users do not understand well or at all. The information service should be able to transpose the information and the jargon into the everyday language of the user, and it should be able to do so without loss of quality of the information. Computers can help in overcoming such language barriers. They can assist in translation from one kind of language to another, and they can produce text automatically in one language while the user inputs information in another. By means of structured text generation computers may be able to write various reports automatically.
  • Literacy. Another barrier to effective communication related to language may arise because the levels of literacy among the potential users are below the reading levels required to comprehend the more technical information in occupational health and safety. Computers offer help in overcoming this barrier with techniques that automatically analyse reading levels of written materials, which can then be assessed for suitability for particular users.
  • Restrictions in distribution and availability. Some information of great importance in occupational health and safety may be classified as confidential. Examples include medical data, trade secrets, and some government documents. Copyright laws also restrict duplication of various types of information. In some circumstances, keeping information confidential is as important a responsibility as disseminating it. Confidentiality of information is a necessary consideration for persons and organizations generating information. Information management involves expertise in the avoidance of problems of confidentiality, for example by using aggregated rather than individual data, and by acquiring detailed knowledge of legitimate requirements to protect the privacy of information.
  • Information access tools (finding aids) used in libraries to search for information. Not all users know how to use advanced information access tools, such as computerized catalogues (see below), and not all information is readily accessible by means of access tools. Most access tools require experience and skill, and good knowledge of the English language as well. Menu systems are an attempt to simplify the searcher’s task, but the simplification may act to conceal information. Such problems can be minimized if information professionals adopt the role of tutor.
  • The computer keyboard. For some people, the computer keyboard is a barrier because they have not been trained to use it. Persons with disabilities such as repetitive strain injury cannot use it for long periods of time or at all. Voice recognition provides an alternative means of communication with the computer.
  • The financial (and environmental) cost of information and document delivery. Paper is a costly medium for distributing information. Although computers are supposed to economize in paper, in practice they can be extremely wasteful of it. Carefully managed computer-based information systems are the most cost-effective (and least environmentally burdensome) way of distributing as well as storing information.

 

Information Services and Libraries

Information services and libraries work together. Large community and special libraries, such as law or medical libraries, often have information services. Specialized information services (including libraries) devoted to occupational health and safety are usually located within organizations such as occupational safety and health institutions, companies, universities and government departments.

The information service undertakes to answer the users’ questions and to keep them informed on important matters. It requires the support of library skills and resources to search for and to obtain the information, and to deal with some copyright matters. The information service analyses the information relative to the needs of the questioners. It compiles answers which frequently involve information from sources outside the scope of a community library (see table 1).

Some information and occupational health and safety experts differentiate between the community library and information services. They argue that unnecessary duplication of effort should be avoided for reasons of cost, if for no other. A rule of thumb is that materials on loan from a community library which is accessible to the information service’s user community should not also be available for loan from the information service. By the same token, the information service should specialize in occupational safety and health information that is not normally available through the community library. The information service should be able to focus on service to groups and individuals with defined needs in occupational safety and health. The information service may also support an organization’s legal obligation to provide or generate information, which a community library could not be expected to do.

Libraries rely on highly developed, computerized systems for the acquisition and cataloguing of materials, and for monitoring and controlling circulation. Information services access these systems through team work with specialist library personnel. The library and the information service need to cooperate closely in the organization of reference materials (materials not available for loan), interlibrary loans, on-line systems and audiovisual materials. The information service would normally have a core collection of important reference materials such as the ILO’s Encyclopaedia of Occupational Health and Safety.

Selective dissemination of information (SDI) is an aspect of information service in which cooperation is especially important between information services and community libraries. To operate a service of SDI, the information provider stores a personal search profile of the user’s needs. A group of profiles for researchers, for example, would be used for scanning the titles of scientific articles as these are published. Titles matching particular profiles are notified to the individuals concerned. While SDI can be an important service, it may be difficult to organize effectively when the information needs of the users vary considerably from time to time, as is often the case in occupational safety and health.

Training for Accessing Information

Workers and managers need to know from whom and from where they can obtain information. For example, Material Safety Data Sheets are an important source of health and safety information about chemicals used in the workplace. Workers and managers need training in seeking out and using this information. Because no occupational health and safety training can possibly cover all potential problems, knowledge about where to look for information is vital for workers and managers. Something about information sources and services should be included in all occupational health and safety training.

Information training is an essential part of the education of professionals, representatives and committee members.

The training assumption is that such people have a good grasp of occupational health and safety but need basic training in information management skills. Such skills include searching on-line information resources, and making effective use of an information service. The training should include practical experience of working as a team with professional library and information staff.

Professional library and information scientists represent the most advanced level of education and training in information work. But in their education they may have had little exposure to occupational health and safety. There is a need to increase this content, and perhaps develop appropriate specialization in the university and college education of this group.

The Computer in Information Management

All of the processes of information management increasingly involve computers. While much of the world’s information is still in paper form, and is likely to remain so for some time to come, the role of computers is increasing in every area. Computers continue to become smaller and less expensive while growing in capability. Inexpensive microcomputers, also called personal computers (PCs), can do the information management work that only a few years ago would have required an expensive mainframe computer. Three key concepts in computing are especially important in information management: databases, database management systems and computer communication.

Databases

A telephone directory is a simple example of a database. The telephone company keeps a master list of names and telephone numbers in a computer. This list is a computer database. Changes to it can be made quickly, so that it is always up to date. It is also used in the printing of the paper version of the telephone directory, which is a database for public access. Individuals and organizations often keep their own lists of frequently used telephone numbers. Such lists are personal or private databases.

The paper version of the telephone directory illustrates the basic form of a database. The information is organized by last (family) name, in alphabetical order. Initials and addresses distinguish individuals with the same last name. For each unique combination of name, initials and address there is at least one telephone number. In database terminology, each line (last name › telephone number) is a record. The names, initials, addresses and telephone numbers are called fields.

The paper form of a large database, such as a telephone directory, has major limitations. If all one has as a starting point is a telephone number, finding a name in a large city’s telephone directory is difficult, to say the least. But this task is easy for the telephone company’s computer. It simply rearranges all the records in numerical order of telephone number. The ease with which records can be rearranged is one of the most useful features of a computer database.

Library catalogues are databases which exist in both paper and electronic form. Each record corresponds to a particular book or article. The fields identify the date and place of publication, and show where a copy can be seen. Library catalogue databases exist for many subjects, including several of relevance to occupational health and safety. The ILO’s CISDOC is an example of such a bibliographic database.

In addition to the names of authors, reference data (such as title, date of publication, name of the journal), a bibliographic database often contains an abstract as well. The abstract serves to inform the searcher of the contents of the article. The user can then decide whether to obtain the full paper.

Databases can store not only abstracts, but also the full text of articles, as well as images (graphics) such as photographs and diagrams. Multimedia is a powerful application of database technology to combine sound, text, and still and moving visual images.

Advances in optical and magnetic storage media have brought down the cost of high-capacity storage. As a result, larger and increasingly complex databases are kept in personal computers or are accessible through them.

Database management systems

Arranging records in a database and many other important information management functions, such as performing a search for particular records, are carried out by means of a database management system (DBMS). The DBMS is software that enables the user to work with the data in the database. The DBMS is thus a vital element in information management. A special form of DBMS software is the personal information manager, used for personal telephone directories, to-do lists, meeting arrangements and other personal data kept by individuals.

The concept of the filter is a useful one for representing the way in which a search is structured by a DBMS. Each search can be seen as a filter which allows passage onwards only of those records that correspond to a particular profile. For example, the user could ask to see all records published on asbestos during the year 1985. The search would be expressed to the computer as an instruction to filter for all records that have the key word “asbestos” in the title and that were published in 1985. A typical instruction would read:

title key word = asbestos AND date of publication = 1985

The operator AND is known as a Boolean operator, named after George Boole (an English mathematician) who devised a system of algebraic logic in the 19th century known as Boolean Algebra. Other commonly used Boolean operators are OR and NOT. Using these, the search filters can be made highly specific.

Computer communications

Computer communications have created numerous networks, formal and informal, by which information is exchanged. Such networks often cover great distances. Many operate through the normal telephone system by means of a modem. Others use satellite communications.

In a typical network, the databases are held in one computer, the target, while a personal computer, the origin, issues the request for a search. The target’s response is to send back the records produced by the search. International standards have been evolved to ensure that this computer-to-computer communication takes place properly. Examples of such standards are ISO 10162 and 10163-1 (both 1993), which relate to search and retrieval.

In the past, computer communications required large and expensive computers. The power and capacity of personal computers is now so great that even an individual can organize networks from his or her own office or home. The network through which the individual connects to the world of information is the Internet. By 1996 this had become the fastest growing communications system the world has ever known, with a predicted one billion users by the end of the century.

An instrument of this growth is the World Wide Web. This software tool set simplifies the complexity of the Internet. With the Web the user needs no knowledge of computer languages or commands. Nor does the user have to rely on the services of an information professional, as was the case in the past. The key tool for the user is a Web browser, a computer program which permits the user to navigate through the Web. With this, millions of Web documents—the information resources of Web—become accessible. Web resources are not limited to text but are also full multimedia presentations that include sound and animation.

The multimedia capability turns the Web into an important training medium. By 1996, occupational health and safety training programmes had begun to appear on the Web. From the larger Web sites, computer programs could be downloaded for use in occupational health and safety. Other Web information resources included the increasing number of library sites of relevance to occupational health and safety on the Web. With the continuing growth of the Web, we could well see within the life span of this edition of the ILO Encyclopaedia the development of a worldwide “virtual university” of occupational health and safety.

The Internet provides the global electronic mail (e-mail) system by which individuals send private messages to each other. Increasingly the Internet is used for voice mail and video-conferencing, as well.

Messaging differs from e-mail. In messaging, all members of the group can read and respond to a message. Messaging is used for computer conferencing in which many people participate in a discussion on a particular topic. It is an inexpensive way to create a network, for example, among occupational health and safety professionals with a common interest in a particular type of occupational hazard.

File transfer is a basic process in computing. In computer terminology, a file is the basic unit of storage that allows the computer to distinguish one set of information from another. A file could be a computer program, a word-processed document, an entire database or a filtered set of records produced by a search of a database. File transfer is the means whereby computers transfer information between themselves. Various file transfer protocols (FTPs) ensure that data are not changed in any way during transfer. The special importance of file transfer for information management in occupational health and safety is that any information service with even a modest personal computer can receive all types of information from information services all over the world. File  transfer  and  associated  services  are  usually  the  most cost-effective method of transferring information. As computer capabilities improve, the breadth and scope of the information that can be transferred increases apace.

An example of on-line transaction processing would be to order a publication through a personal computer. Another example is contributing an item of data to a computer in a distant city in connection with a research project involving several geographic regions.

Other forms of computer communication that play an increasingly important role in occupational health and safety are computer-based faxback services. The user telephones the computer to order specific information. The computer then sends the information to the caller’s fax machine.

In overview, it can be said that the computer is not only the main instrument for information management, but also the great facilitator of the information revolution that continues to gather momentum in the field of occupational safety and health, as in other important areas of human activity.

Introduction

Unlike problems that command the attention of the industrialized countries with respect to pesticide hazards, namely, chronic occupational exposure and environmental contamination, the major threat posed by pesticides in many developing countries is acute poisoning itself. A recent estimate by the World Health Organization (WHO) puts the annual number of severe poisonings at 3 million, with about 220,000 deaths. It is a matter of further concern that, based on a survey of self-reported minor poisoning in four Asian countries, it was shown that each year 25 million agricultural workers in the developing countries are exposed to the danger of acute pesticide poisoning (Jeyaratnam 1990).

In Malaysia, a largely agricultural country, the use of pesticides is relatively prevalent. In Peninsular Malaysia alone, about 1.5 million hectares of land are devoted to the cultivation of rubber trees and 0.6 million hectares to oil palm trees. The employment of almost 4.3 million people is related to agriculture.

The principal legislation for the control of pesticides in Malaysia is the Pesticides Act of 1974. The main intent of this Act is the control of the manufacture and import of pesticides through registration. Other aspects of control include the licensing of premises selling pesticides and storing them for sale, the proper labelling of pesticides, and control of the import of unregistered pesticides for research and educational purposes (Tan et al. 1992).

Surveys carried out by the local agrochemical industry showed that in 1987, most of the estimated 715,000 rubber and oil palm smallholder farmers used paraquat (Shariff 1993). Over a ten-year period (1979–1988), pesticides accounted for 40.3% of the total number of 5,152 cases of human poisoning in Malaysia. Paraquat contributed 27.8%, other weed-killers 1.7%, malathion 4.7%, other organophosphates 2.1%, organochlorine compounds 2.6%, and other pesticides 1.4%. Annually, 230 million ringgit (MYR) is spent on weed-killers alone (Tara et al. 1989). It has been estimated that about 73% of poisonings involving paraquat are suicidal, compared with 14% due to accidents and 1% due to occupational exposure (Jeyaratnam 1990).

Poisoning cases due to pesticides have not been well documented. However, such incidents do occur, according to a number of selected studies. A survey showed that poisoning had occurred in 14.5% of the 4,531 farmers growing vegetables, flowers and fruits in the Cameron Highlands. Hospital admissions showed 32.1% were accidental pesticide poisoning and 67.9% suicidal cases. In Tanjung Karang, a paddy growing area, 72% of rice farmers experienced poisoning symptoms when handling pesticides, and proper clothing, goggles, shoes and respiratory masks were seldom worn. In 1989, 448 pesticide workers received medical treatment at government hospitals (Lee 1991).

In another study (Awang et al. 1991) conducted in a predominantly agricultural area, it was reported that 12.2% out of a total of 264 poisoning cases treated in a teaching hospital were due to pesticides. In yet another study (Majid et al. 1991) serum pseudocholinesterase levels, which were used as an indicator of exposure to the organophosphates, were found to be significantly lower in vegetable farmers: the degree of decrease in these blood levels is dependent upon the length of exposure to these pesticides.

The use of pesticides in Malaysia has caused serious concern. A recent report by the Malaysian Factories and Machinery Department, an agency that enforces the Occupational Safety and Health Act, revealed that the accident rate for improper handling of pesticides is four times higher than that of other industries, and is as high as 93 per 1,000 workers as compared with the national average of 23 per 1,000 (Rengam 1991). This seems to indicate that there is an insufficiency of educational materials and information on safety and an apparent lack of caution in the handling of pesticides. A 1994 report also highlighted the death of about 70 cattle, suspected to be due to paraquat poisoning as a consequence of the animals’ re-entry into a sprayed area (New Straits Times 1994).

Clearly there is an urgent need not only to collect data but also to facilitate education among those involved in the use of pesticides. It is with this in mind that a pesticide information service was developed and a pilot information system was launched throughout the country in 1989. It is part of the Integrated Drug and Poison Information Service (IDPIS) of the National Poison Centre based at the Universiti Sains Malaysia (USM) at Penang.

The primary aim of the IDPIS is to disseminate information concerning health-related matters, especially with regard to drug usage and poison control, to health professionals and the public alike (Razak et al. 1991).

The pesticide information service, which was launched through the videotex system, has had the welcome side-effect of opening up new possibilities for several other databases important for health care. IDPIS databases were continually being used as a guide for the development of other databases for the management of information relating to pesticides, industrial and household chemicals and food supplements. The Pestinfo system was one such product; it was initiated by IDPIS in collaboration with the Pesticide Board (the Malaysian pesticide regulatory body) and the Malaysian-German Pesticide Project. This arrangement has been conspicuously successful in terms of information validation and the evaluation of information needs in view of countrywide trends in pesticide use.

This system is focused on registered pesticides in Malaysia, but could also cater to those found throughout the Asia-Pacific region. To date, information on more that 500 biochemically active substances has been incorporated into the pesticide information system, with some 3,000 commercially available products and their profiles listed. The system is available in two modes, namely, via a videotex system and also through a computer network utilizing PCs. The former facility is called Pestinfo, while the latter is called the Pesticide Information System (see figure 1).

Figure 1. Information flow and relational access in the Pesticide Information System

Pestinfo

The Pestinfo system is the first to be made available in this region and operates via TELITA, Malaysia’s National Videotex System. Operated by Malaysia’s Telecommunication Company, TELITA provides nationwide access that is both cheap and fast. TELITA can be accessed through a television set and a decoder or a computer system equipped with a modem connected to a telephone network (Siraj 1990). Such a system is economical as each dial-up costs only MYR 0.13 (less than US$ 0.05) and access time is charged at only MYR 0.08 a minute. It is internationally unique in its approach in that it is both professional- and community-based. Information in Pestinfo is collectively packaged with two other closely interrelated on-line databases (called Drugline and Poisonline) to maximize the relational information provided to the end-user.

Pestinfo can be accessed by members of the public and by professionals alike, including those in the agricultural sectors, whether extension workers or field workers. All the databases are well integrated, and yet independent, so that all pertinent data can be easily accessed. For this reason, the USM’s Pestinfo is sequentially arranged into at least 15 subcategories.

End-users who are health care providers are also able to gain direct access to Poisonline, which carries further specialized details with regard to patient management in cases of poisoning.

Poisonline by itself is in fact a broad-base information module covering several classes of poisons, including pharmaceuticals, as well as industrial and household chemicals, food and cosmetics. It provides information on poisoning signs and symptoms according to anatomical systems, on treatment and management modalities, and on aspects of poisoning prevention. Also included are detailed antidote information and emergency treatment procedures.

The on-line Poisoning Reporting System is an outstanding feature incorporated in Pestinfo, and in Poisonline as well. This feature enables first-line reporting to be done electronically by the end-user, through a specially designed format, when any case of poisoning is encountered. It not only allows automatic documentation of all the cases reported, but simultaneously acts as an instant referral system which permits follow-up to be done systematically. Through the reporting system too, initiation of the appropriate immediate response can be undertaken to further assist the user in the management of the poisoning case. Data obtained via the Poisoning Reporting System will automatically be stored in a PC-based network system to make it possible to generate statistical reports.

Additionally, all users of Pestinfo will be able to access several other user-friendly databases on public education with emphasis on health, especially in pharmaceutical-related areas. These databases aim to educate the public on proper chemical and drug use and the maintenance of good health. The main database designed for this purpose is designated Public Infoline.

An attractive feature with regard to public education is the “Ask Your Pharmacist” service, which provides an electronic mail service for questions and answers concerning any topics relating to health. This is available free to all users.

The Pesticide Information System

The initial experience with Pestinfo has led to the development of the Pesticide Information System, which offers new possibilities of information processing for purposes of identification in cases of poisoning and can serve as a medium of reference for extension workers as well as a means of compiling poisoning events that could be of assistance in policy decision-making and planning for health centres. Because the videotex system was not fully equipped to meet these needs, an application that provides several flexible search functions was developed using the PC.

As mentioned earlier, the pesticide information service is complemented by a user-friendly network-based microcomputer system that runs on IBM-compatible PCs. This application is called the Pesticide Information System Version 2.3 and has been specially designed for maintenance of up-to-date documentation as well as for the processing of poisoning records received electronically or otherwise. It can be instructed to produce baseline statistical reports as well as to respond to other data manipulation requests as stipulated in the software. It is thus more flexible in retrieving information, given the added processing and interactive powers accorded to it by each PC. It was designed using dBase3 Plus and compiled under Clipper Summer 5.0.

The Pesticide Information System contains additional relevant information which can be readily accessed either by pesticide name, composition, registration number and name of the manufacturer or registrant of each and every product registered in the country. The main menu of the System is described in figure 1. The System is particularly suitable for use by health professionals as well as by agriculture-based personnel since it can be loaded on a portable computer.

To date, more than 50% of the poisoning cases received on-line have been pesticide-related (Latiff et al. 1991). The combination of the two modes of operation described above has undoubtedly enhanced the running of the Pesticide Information System, making possible an even faster response to a broader range of inquiries.

Future Directions

The task of compiling and disseminating pesticide information to users has been very successful even though it has been carried out on an informal basis. IDPIS has also taken new directions in the light of the rapid progress in hardware and communication technology. For instance, network-based applications will also be linked up to users nationwide through a collaboration with a network communications company that supports and provides communication link-ups for the whole country. This will further enhance the communicability of health information, as this sort of arrangement ensures economical solutions to both the user and to IDPIS as the information provider.

Currently, IDPIS operates on two networks, namely Token Ring and Ethernet, for the purpose of research and development work in information systems (figure 2). The former is installed at the University Teaching Hospital. Both networks are connected to an IBM RISC6000 so that information and resources within the servers of the two networks can be shared and coordinated to provide facilities for education, training and research. The networks will be designed to incorporate a tool for surveillance in the areas of pharmacoepidemiology and toxicovigilance.

Background

Thailand has a population of approximately 59 million people and a land area of 514,000 square kilometres. The population growth is 1.7% per annum. The labour force in 1995 was 34 million of whom 33 million were employed and 1 million unemployed. About 17 and 14 million people were employed in the agricultural and non-agricultural sectors respectively.

In the past, Thailand has been an agricultural economy, exporting more rice and tapioca combined than other country, but during the 30-year period 1960–90 the Thai economy underwent dramatic structural changes. Manufacturing has assumed the leading role in terms of its contribution to the GDP. These changes have made Thailand one of the fastest growing economies in the region, with a rapidly expanding manufacturing sector supplying textiles, garments, electrical and electronic goods, gems and jewels and dozens of other products for local and world markets.

The Royal Thai Government is greatly concerned for the welfare of Thai workers in both the industrial and the agricultural sectors. This concern has led to seminars stressing the need for effective measures to improve the working conditions and environments of workers in various sectors and work situations. In light of all the issues taken into consideration, the National Institute for the Improvement of Working Conditions and Environment (NICE) was established through collaborative arrangements between the Royal Thai Government and the United Nations. NICE became a division under the Department of Labour Protection and Welfare (DLPW), which has the primary responsibility for the protection of workers in Thailand and seeks to achieve its objectives through strengthening the existing institutional systems procedures and technical capabilities of DLPW.

The objective of NICE is to improve the protection of workers from occupational accidents and diseases and from unsatisfactory working conditions. Its main activities are as follows:

  1. the development and implementation of training programmes in occupational safety and health and in working conditions
  2. the development and operation of a management information system (MIS) to centralize all information collected and to provide a basis for planning, evaluation and coordinating policies and programmes for improving working conditions and the environment
  3. the development of a visible focal point for national exchange of information and expertise on working conditions and the environment
  4. providing technical support to increase the capability of those inspection staff who handle working conditions and the environment
  5. providing laboratory facilities in occupational hygiene, work physiology and ergonomics, and testing of safety equipment
  6. provision of support, through research and technical advisory services, for example, for extending protection to small-scale enterprises.

 

NICE has a staff of 50 professionals and is divided into the following sections: General Administration, Work Environment, Ergonomics and Work Physiology, Safety Technology, Safety Promotion and Training, Safety and Health Information Centre, Audiovisual and 12 regional centres in industrial estate areas throughout the country.

National Occupational Safety and Health Information Centre of Thailand

In order to improve NICE’s ability to meet its objective more effectively, NICE, in collaboration with the Geneva-based International Occupational Safety and Health Information Centre of the International Labour Office, established the National Occupational Safety and Health Information Centre of Thailand. The Centre is concerned primarily with collecting information on occupational safety, health and working conditions, from Thailand and abroad, processing and storing it and disseminating it to employers, workers, their respective organizations and related bodies and others having need for such information. This Information Centre comprises a reference library, a documentation unit, an inquiry service and a computer unit.

The library

When it opened, this library possessed only a few hundred books; now, the collection comprises approximately 3,000 book titles and 20,000 titles of microfiches on various topics on occupational safety and health such as occupational disease, safety and health engineering and working conditions. Furthermore, since 1983, the library has subscribed to 27 English-language publications and ten Thai journals. Thirty videotape titles on display and posters are available. The library’s outreach to safety and health professionals is continually expanding.

The documentation unit

The duty of this unit is to produce an occupational safety and health newsletter; guidelines, handbook and code of practice; a brochure; and information sheets.

1. The safety and health newsletter. Four newsletters are produced annually, each presenting such various offerings as safety and health updates, research news, interviews, statistics, and so on. There are 6,000 copies of each newsletter produced annually.
2. Information sheets. These are divided into four groups of topics including:

  • safety and health in general, e.g., safety construction, fire prevention, and ventilation in the workplace
  • practical use for safety, for example, the safe use of hand tools, or the safe use of electrical equipment
  • chemical data such as might relate to sodium hydroxide or ammonia
  • laws and legislation on safety, such as would concern safe working environments, and much more.

3. Recently, the documentation unit produced 109 titles of information sheets and 10,000 copies of each was printed, making an aggregate of over a million copies.
4. The guideline, handbook and code of practice. As of the mid-1990s 15 titles of this publication had been produced; for example, one of these included a guideline for the safe handling of pesticides and a handbook for first aid in industry. Each publication was printed in 3,000 copies.
5. Brochures. Ten titles of brochures were produced, having to do, for example, with the use of ear plugs at work. Of each title, 5,000 copies were printed, giving an aggregate of 50,000 copies.

The inquiry service

The inquiry service was set up with the purpose of seeking answers to questions on occupational safety and health from every person concerned in this field: labour inspectors, safety officers, employers, employees, students and others. All inquiries can reach the centre by post, telephone or facsimile. Before sending out every answer, all information is checked by NICE technical staff for correctness.

Each year, approximately 600 inquiries are sent to the centre.

The computer unit

As the focal point for collecting and exchanging information, expertise and practical experience in the area of occupational safety and health, NICE has built up several databases: on industrial establishment, accident investigation reports, labour inspection reports, safety officers, major hazards installation, boiler inspection reports, work environment inspection reports and workers’ health screening reports. In order to enhance the ability of this unit, NICE has developed a centralized computer system which  will  serve  as  the  host  database  on  occupational  safety and health. This work has been done with assistance from the International Development Research Centre (IDRC) and the International Labour Organization. Meanwhile, the local area network (LAN) between NICE and the other Regional Centres on Occupational Safety and Health has been established. This linkage will help the staff from a Regional Centre to access information from NICE databases and from various CD-ROM databases in the NICE computer unit.

In order to promote as its direct concern the improved working conditions and the safety and health of Thai workers throughout the country, all the services of NICE are free of charge and NICE now supports all labour inspectors, approximately 5,000 safety officers, about 650 organized trade unions of medium- and large-size enterprises, employers and employees throughout the country. Therefore, NICE still moves on developing and strengthening its ability to protect workers from unsatisfactory performance and injuries due to unsafe working conditions and hazards in the environment.
