What is occupational hygiene?

Occupational hygiene is the science of identifying, assessing, and controlling workplace hazards that can affect worker health and safety. It focuses on preventing exposure to hazardous substances, physical agents, and environmental risks to create healthier and safer workplaces.

What Does Occupational Hygiene Cover?

Occupational hygiene includes the assessment and control of:

·       Hazardous chemicals – including asbestos, lead, silica dust, and solvents

·       Airborne contaminants – such as dust, fumes, vapours, and gases

·       Noise and vibration – monitoring and reducing exposure to harmful levels

·       Thermal stress – managing heat stress or cold exposure in workplaces

·       Biological hazards – exposure to bacteria, viruses, and mould in certain industries

·       Ergonomic risks – ensuring workplace design supports worker health

Why Is Occupational Hygiene Important?

Poor workplace hygiene can lead to long-term health effects, including:

·       Respiratory diseases (e.g., asbestosis, silicosis, occupational asthma)

·       Hearing loss from prolonged noise exposure

·       Chemical poisoning or skin conditions

·       Increased risk of workplace injuries and chronic illnesses

Who Regulates Occupational Hygiene in Australia?

Occupational hygiene is guided by:

·       Safe Work Australia – develops national work health and safety (WHS) policies

·       State and territory regulators (e.g., WorkSafe Victoria, SafeWork NSW) – enforce WHS laws

·       Australian and international standards (e.g., AS/NZS 1715 for respiratory protection)

How Is Occupational Hygiene Managed in Workplaces?

·       Hazard assessments – monitoring air quality, noise levels, and chemical exposure

·       Control measures – using ventilation, PPE, and safer work practices

·       Training and education – ensuring workers understand risks and how to manage them

·       Health surveillance – regular monitoring for workers exposed to hazardous substances
