NOTES1

  1. Severe and even fatal poisonings by phosgene have been reported for gluers who smoked while working with glues containing organohalogen solvents. When inhaled through a burning cigarette, such solvents are decomposed and partially converted into phosgene.
  2. A hazard peculiar to gluers is the possible bonding of finger-to-finger, particularly when working with cyanoacrylate and some epoxy glues.
  3. Severe injury may be caused, in particular during airless spray gluing, by high-pressure cutaneous injection of glue into the hands or arms.
  4. “Glue sniffing”, and the related intoxication and neurotoxic effects, are a significant hazard because of the easy access to glues.
  5. The use of benzene as a glue solvent has been banned in many countries.
  6. Eye injuries have been caused by bursting of glue (in particular cyanoacrylate) during hard squeezing of tubes whose opening was clogged by a small amount of hardened glue.
  7. Increased incidences of sinonasal cancer, rectal cancer and multiple sclerosis have been reported for gluers.

– Accidental injury caused by firearms while hunting animals (for zoos, etc.);

– Fire hazard at animal-waste rendering plants;

– Fires and explosions caused by inflammables and explosives;

– Eye injury caused by metallic splinters (e.g., in farriers while horseshoeing, or while branding);

– Burns from hot metal objects (e.g., in farriers while horseshoeing);

– Electric shocks caused by defective or incorrectly operated electric and electromechanical equipment;

– Explosions of animal-food dust-air mixtures.

Physical hazards

PHYSHA

– Exposure to ionizing radiation emitted by veterinary x-ray equipment and by laboratory animals investigated or treated with radioisotopes;

– Exposure of skin and eyes to ultraviolet radiation used for sterilization and other purposes in laboratories and animal quarters;

– Exposure to excessive noise, heat stress and hand-arm mechanical shocks and vibrations during forging and related operations (in farriers);

– Cold or heat stress (resulting in effects ranging from temperature discomfort to frostbite or heat stroke, respectively) and exposure to frequent abrupt temperature changes (when entering or leaving climate-controlled rooms) in animal handlers working mostly or partly outdoors under severe climatic conditions;

– Health problems (e.g., rheumatic, etc.) due to conditions in animal quarters such as high humidity, concrete floors, etc.

Chemical hazards

CHEMHA

– Intoxication due to contact with chemicals, such as pesticides (especially insecticides, germicides and herbicides), solvents, strong acids and alkalis, detergents, etc.;

– Dermatoses due to contact with chemicals, such as pesticides, solvents, detergents, deodorants, animal medications, etc.;

– Allergies due to contact with formaldehyde and other synthetic or natural allergenic substances;

– Health hazards caused by inhaling formaldehyde vapours;

– Health hazards caused by exposure to metallic, solvent and other fumes during forging, shoeing and other hoof-care operations (especially in farriers);

– Systemic and gastrointestinal effects caused by exposure to cytotoxic agents (especially in laboratory animal handlers);

– Exposure to various carcinogenic, mutagenic and teratogenic agents (especially in laboratory animal handlers);

– Mercury poisoning (in fur-processing workers).

Biological hazards

BIOHAZ1

– Infection due to contact with sick or pathogen- carrying animals or due to exposure to airborne pathogens, resulting in development of communicable diseases (zoonoses), including: anthrax, blastomycosis, brucellosis (undulant fever), B-virus (simian B disease), cat-scratch fever, echinococcosis (hydatidosis), encephalitis, enteritis (zoonotically acquired), erysipeloid, glanders, hookworm diseases, leptospirosis, Orf virus disease, ornithosis, pasteurellosis, plague, pseudocowpox, psittacosis, pyogenic infections, Q-fever, rabies, rat-bite fever, rift-valley fever, ringworm diseases, salmonellosis, swineherd’s disease, tapeworm diseases, toxoplasmosis, tuberculosis (bovine), tularaemia, typhus fever, etc., as well as other diseases related to protozoan parasites, rickettsia and chlamydia, viral and fungal infections, etc.;

– Laboratory-animal allergies (LAA) (including: occupational asthma, allergic alveolitis, bronchitis, pneumonitis, rhinitis, skin rashes, etc.) and diseases of the airways caused by inhalation of animal-food dust containing various micro-organisms and their spores, animal hair (causing furrier’s lung), bird-droppings residues (causing pigeon- breeder’s lung), etc.;

– Pulmonary dysfunctions in animal confinement workers caused by various agents, including hydrogen sulphide toxicity, bronchitis, non-allergic asthma, organic-dust toxic syndrome (ODTS), mucous membrane irritation, and by bioaerosols and endotoxins;

– Dust- and endotoxin-related respiratory effects in animal-feed workers and in fur-farm workers;

– Exposure to carcinogenic afflatoxins (causing primary liver cancer) of animal-feed workers;

– Cancer hazards due to carcinogens present in pesticides, animal medicines, etc.;

– Acute health effects caused by various flea-control products used by animal handlers;

– Increased risk of laboratory-acquired haemorrhagic fever with renal syndrome (HFRS) caused by infected laboratory rats;

– Occupational eczemas and contact dermatitis;

– Increased risk of developing chronic lymphatic leukaemia (CLL) and non-Hodgkin’s lymphoma (NHL) in animal breeders;

– Various septic infections;

– Development of the mad-cow syndrome (viral) disease.

Ergonomic and social factors

ERGO

– Musculoskeletal problems (particularly of back and knees) in animal handlers engaged in lengthy horse-riding and/or leaning on their knees (especially on concrete floors) during work (e.g., in farriers);

– Job dissatisfaction related to the working environment (dirt, smells, etc.) and to the mainly physical character of work;

– Exposure to attacks by cattle robbers, valuable-pet thieves, etc.;

– Exposure to protest, and possibly violence, by animals’ rights groups;

– Danger of developing drugs addiction facilitated by easy availability of animal medications.
