Occupational Hygiene is generally defined as the art and science dedicated to the
Anticipation, Recognition, Evaluation, Communication and Control of environmental stressors
in, or arising from, the work place that may result in injury, illness, impairment, or affect
the well being of workers and members of the community. These stressors are normally divided
into the categories Biological, Chemical, Physical, Ergonomic and Psychosocial .

- The recognition of environmental
factors associated with work and
work operations which may adversely
affect health.
- The evaluation of environmental

Occupational Hygienists
Occupational Hygienists are qualified to recognise and evaluate all, or some,
of a range of hazards likely to be encountered in the workplace.
These include hazardous substances such as dusts, gases, vapours, mists
fumes and bulk materials; ionising and non-ionising radiation, noise and vibration,
lighting, thermal stress, biological hazards and musculo-skeletal stressors.
Occupational Hygienists require a knowledge of toxicology, physiology,
occupational diseases, epidemiology, ergonomics and occupational health and safety law.
They also require an understanding of the principles of hazard control including
process modification, ventilation and personal protective equipment and
associated administrative measures.
Many hygienists are able to provide Occupational Health training to others
so that everyone in the workplace can become a better team member in the campaign
to achieve a healthier workplace.
