Occupational Hygiene

Occupational Hygiene is the formal scientific evaluation of hazards at work. This scientific evaluation may often involve aspects of public and environmental health.

Occupational Hygiene is best known for determining the exposure aspects of hazard identification and risk assessment. Occupational hygiene monitoring accompanies an organisation’s overall risk management of occupational health and safety issues.
Results are often used to determine exposure to workplace contaminants.


These contaminants may be of the following forms:


Physical: noise, vibration, thermal stress (excessive heat or cold), ergonomics/manual handling and non-ionising radiation such as electromagnetic fields, microwave or radio frequency radiation.

Chemical: solvents, metals and metal fumes, airborne particles, any petroleum based chemicals, combustion by-products, or any emissions from chemical, industrial, construction, demolition or earthworks sites.

Biological: mould, yeast, bacteria such as Legionella, vermin and wildlife.


Environmental: these hazards are often generated offsite but may have an effect onsite. They may include all of the hazards mentioned above as well as general pollution such as noise and natural hazards such as storm events and bushfires.
