Occupational Hygiene Services for Australian Workplaces
Every workplace carries health hazards — many of them invisible. Airborne chemicals, noise, dust, heat, and biological contaminants can build up over time and cause serious long-term harm to workers long before anyone notices a problem.
Anitech’s occupational hygiene services are designed to find those hazards before they find your workers. Our certified occupational hygienists apply scientific monitoring and risk assessment across all workplace hazard categories, delivering the measurements, reports, and practical control recommendations your business needs to stay compliant and keep people healthy.

What Are Occupational Hygiene Services?
Occupational hygiene services are professional assessment and monitoring services that identify, measure, and control health hazards in the workplace. The discipline covers five categories of hazard: chemical, physical (including noise and vibration), biological, ergonomic, and psychosocial.
Occupational hygiene is distinct from general WHS consulting. A WHS consultant helps you manage safety systems and paperwork. An occupational hygienist uses scientific instruments — air samplers, noise dosimeters, heat stress monitors, and biological sampling equipment — to quantify what your workers are actually being exposed to and compare those measurements against Australia’s regulatory limits.
If your workers are exposed to dust, chemicals, noise, or other airborne hazards, you don’t just need a policy — you need measurements. That’s what occupational hygiene services deliver.
Occupational Hygiene Services Anitech Provides
Anitech offers a full range of occupational hygiene monitoring and consulting services across Victoria and nationally:
- Air monitoring and chemical exposure assessment — measuring airborne concentrations of dusts, fumes, vapours, and gases against Australia’s Workplace Exposure Limits (WEL)
- Noise assessment and audiometric testing — measuring workplace noise levels and worker exposure to assess compliance with the 85 dB(A) action level
- Silica dust monitoring — specialised respirable crystalline silica (RCS) sampling for construction, manufacturing, and mining environments. Learn more about silica dust monitoring →
- Asbestos air monitoring — clearance and ongoing monitoring for asbestos disturbance and removal projects. Learn more about asbestos air monitoring →
- Indoor air quality (IAQ) testing — assessing VOCs, CO₂, particulate matter, humidity, and mould in commercial and industrial buildings
- Fit testing for respiratory protective equipment — qualitative and quantitative testing to verify respirator fit for your workers
- Heat stress assessment — WBGT monitoring for outdoor, underground, and high-temperature work environments
- Occupational hygiene audits and program reviews — assessing your existing monitoring program against regulatory requirements and best practice
Each service results in a formal occupational hygiene report documenting measurements, findings, risk levels, and prioritised control recommendations — the documentation your business needs for WHS compliance records.
Your Legal Obligations Under Australian WHS Law
As a Person Conducting a Business or Undertaking (PCBU), you have a primary duty of care under the Work Health and Safety Act to eliminate or minimise risks to worker health so far as is reasonably practicable. For workplaces involving hazardous exposures, this duty requires more than a risk assessment on paper.
From 1 December 2026, Safe Work Australia replaces the Workplace Exposure Standards (WES) list with the Workplace Exposure Limits (WEL) list — tightening permissible airborne concentrations for hundreds of substances. Businesses that are not already conducting exposure monitoring risk being non-compliant when the new limits take effect.
Specific obligations that trigger the need for occupational hygiene services include:
- Health monitoring where workers are exposed to hazardous substances listed in the WHS Regulations
- Air monitoring wherever there is a risk of exposure to airborne contaminants above workplace exposure limits
- Noise monitoring where workers may be exposed at or above the 85 dB(A) action level
- Record keeping — exposure monitoring records must be kept for a minimum of 30 years (40 years for asbestos-related monitoring)

How Anitech’s Occupational Hygiene Consulting Works
Engaging Anitech for occupational hygiene services follows a clear, structured process:
- Initial consultation — we discuss your workplace, processes, materials, and any known or suspected hazard sources.
- Site walkthrough — our hygienist conducts a preliminary inspection to identify hazard sources and plan the monitoring strategy.
- Monitoring and sampling — we deploy calibrated instruments and collect samples in accordance with Australian standards and Safe Work Australia guidelines.
- Laboratory analysis — samples are analysed by a NATA-accredited laboratory, providing legally defensible results.
- Formal report — we deliver a comprehensive occupational hygiene report covering: monitoring methodology, measured results, comparison to WES/WEL limits, risk assessment, and prioritised control recommendations.
- Follow-up — where controls are implemented, we can conduct repeat monitoring to verify their effectiveness.
Our reports are structured to meet regulatory requirements and are accepted by WorkSafe Victoria and other state regulators.

Frequently Asked Questions
How much do occupational hygiene services cost?
Costs vary depending on the type of monitoring, the number of samples required, laboratory analysis fees, and the complexity of the workplace. Most single-service assessments (e.g. a noise assessment or air monitoring visit) range from a few hundred to a few thousand dollars. Anitech provides detailed quotes based on your specific requirements — contact us for an obligation-free estimate.
How often does occupational hygiene monitoring need to be done?
There is no single mandated frequency — it depends on the hazard, whether anything has changed in the workplace, and your regulatory obligations. For hazardous substances, the WHS Regulations require monitoring whenever there is a risk of exposure above the WEL. For noise, monitoring is required where the action level may be exceeded. Your hygienist will recommend an appropriate schedule based on your risk profile.
Do I need a certified occupational hygienist or can a WHS consultant do this?
For workplace health hazard monitoring that will be used for regulatory compliance or legal defence, you need a qualified occupational hygienist — ideally one holding the Certified Occupational Hygienist (COH) designation from the AIOH. General WHS consultants are not trained in the scientific measurement and risk assessment methods that occupational hygiene requires. Learn more about what an occupational hygienist does →
What does an occupational hygiene report include?
A comprehensive occupational hygiene report documents: the scope and purpose of the assessment, the monitoring methodology and equipment used, the results of all measurements and samples, a comparison of results against applicable WES/WEL limits, a risk assessment for each hazard, and a prioritised set of control recommendations. Anitech’s reports are structured to meet Safe Work Australia and state regulator requirements.
How do I choose an occupational hygiene company?
Look for COH-credentialled hygienists, NATA-accredited laboratory partnerships, demonstrated experience in your industry, and clear reporting standards. Avoid firms that sub-contract monitoring to uncredentialled staff or provide reports without detailed methodology sections. How to choose an occupational hygiene company — a full guide →
