Frequently Asked Questions (FAQ) – Occupational Hygiene

Q: What is an occupational hygiene consultant?

An occupational hygiene consultant is a qualified professional who identifies, assesses, and controls health risks in the workplace. This includes hazards such as respirable crystalline silica (RCS), asbestos, dust, noise, chemical vapours, and poor indoor air quality. Their goal is to protect workers' health and ensure compliance with WHS laws.

Q: Do I need an occupational hygiene consultant for my business?

If your workplace involves activities like cutting stone or concrete, handling chemicals, demolition, welding, or working in noisy environments, then yes — you likely need an occupational hygiene consultant. They help you meet SafeWork NSW requirements and reduce the risk of illness, injury, or prosecution.

Yes. Under the NSW Work Health and Safety Regulation 2017, employers (PCBUs) must manage risks to health from airborne contaminants, noise, and hazardous substances.
