Search Tips

The site's search feature is designed to allow users to quickly and easily find encyclopedia and other site content. To use it, simply type your search terms in the "I am looking for..." box and press Enter. You will then see a list of results based on your terms and can further refine your search.

The results page gives you a few additional options to help refine your search. In addition to adding or removing search terms you can choose whether the search should look for all your terms separately or as a phrase. Searching for a phrase can be very useful, for example if you wanted to find articles that contained the phrase "genetic toxicity" but not articles that simply contained both "genetic" and "toxicity" somewhere in their text.

Some basic tips:

  • Use the most specific search terms possible. Searching for terms like "injury" or "occupation" by themselves will return many results may not help you find exactly what you want.
  • Use as few search terms as possible. A search for "chemicals that are dangerous to humans" contains a number of words that are not relevant to the search. Searching for "human toxic chemical" will yield much better results.
  • Try a single term or a pair of terms first. If you don't know exactly what you're looking for start by entering one or two search terms. Based on the results of that search you can decide what additional terms to add in order to narrow down your search.
  • Do not enter questions. A search for "what are common injuries in the construction industry" will not work because that question does not appear anywhere on the site. Search instead for terms like "construction injury".

About the ILO Encyclopaedia of Occupational Health & Safety

The ILO Encyclopaedia of Occupational Health and Safety is a comprehensive tool for academia, journalists and the general public – anyone interested in obtaining data and other information about safety and health at work.
The latest edition of the Encyclopaedia, taking advantage of the information technology revolution, has evolved into an online knowledge-sharing resource, with a user-friendly interface in English, French and Spanish.
The transformation of the Encyclopaedia from a printed issue to an electronic and online platform enables quick and easy access to the most up-to-date information in the occupational safety and health (OSH) field.
The Encyclopaedia website will serve as a cutting-edge global tool for OSH information and especially good practices. The Encyclopaedia is written and compiled by world class researchers and industry experts, and will be updated regularly by different contributors around the world.  The online platform is also connected to a wide variety of ILO health and safety resources and third party information sources (such as online databases and websites).

The site includes a wide variety of health and safety resources from the ILO and other organizations, up-to-the-minute OHS news feeds and more. Encyclopaedia and website content are undergoing a contiuous revision process. For more information on the ILO and Safework visit the Safework website; for further information about the site and the encyclopaedia, contact ILO Safework/CIS: This email address is being protected from spambots.
