Occupational Hygiene Testing Sydney | In-Depth Assessment
Looking for occupational hygiene testing at your site in Sydney?
At Enviro Corp, our in-house team of occupational hygienists can undertake expert testing for airborne contaminants, noise, ergonomics, and a range of other workplace exposures across Sydney. Under the WHS Regulation 2017 (NSW), PCBUs have a legal duty of care to ensure at-risk workers are not exposed to hazards above the relevant exposure standards — and occupational hygiene testing is how that duty is actually demonstrated, not just documented.
Enquire below with your query and one of our occupational hygienists will get in touch with you.
Why Use an In-House Occupational Hygiene Team
Some hazards can’t be managed with a policy document alone — they need to be measured, quantified, and assessed by people with genuine technical training to do so properly. Rather than a single generalist covering every discipline, we maintain a dedicated team of occupational hygienists, and every report is written specifically for your site — not a templated output with the client name swapped in.
- Depth over breadth — in-depth assessment requires specialist training per hazard type
- Defensible compliance — quantitative data from qualified hygienists and NATA-accredited laboratory analysis holds up under audit and tender scrutiny
- One provider, full picture — no need to engage separate specialists for air, noise, and ergonomic risk
Our Occupational Hygiene Testing Services
Airborne Exposure Monitoring
Airborne exposure monitoring refers to testing of airborne hazards in the workplace — dust, fumes, chemical vapours, and other contaminants. SafeWork Australia maintains a comprehensive list of airborne contaminants, some of which are classified as carcinogens, so testing isn't optional for at-risk workers.
How the testing works: we carry out airborne monitoring by attaching calibrated air sampling equipment to a worker during their normal work shift, capturing genuine, real-world exposure data rather than a single spot measurement. This gives meaningful data to implement proper control measures, and to make changes where exposure sits above guideline limits. Our hygienists follow up-to-date sampling methodologies and adhere to the SafeWork Australia Workplace Exposure Standards for Airborne Contaminants. All laboratory analysis is conducted by independent NATA-accredited laboratories.
Workplace Noise Assessments
Excessive workplace noise is a leading cause of permanent hearing loss claims, and a specific compliance duty under WHS law. We measure noise levels (dBA readings) against the exposure standard, identify high-risk zones and equipment, and recommend practical controls — hearing protection zones, engineering controls, or PPE.
Ergonomic Assessments
Poor workstation and workplace design drives fatigue, musculoskeletal injury, and occupational overuse syndrome (OOS). Our ergonomic assessments cover workstation layout, work practices and posture, and provide practical recommendations to reduce injury risk — for office, industrial, and hybrid environments.
Indoor Air Quality (IAQ) Testing
Poor indoor air quality contributes to "sick building syndrome" — eye, nose, and throat irritation, fatigue, headaches, and reduced productivity. Our IAQ testing covers carbon dioxide, carbon monoxide, temperature, relative humidity, particulate matter (PM10/PM2.5), bioaerosols (airborne bacteria and mould), and volatile organic compounds (VOCs), benchmarked against relevant guideline levels.
Silica Dust Monitoring
Respirable crystalline silica (RCS) is a significant risk in construction, quarrying, and manufacturing, and a specific area of regulatory focus. We conduct silica dust monitoring to determine worker exposure levels against the workplace exposure standard, supporting your control measures and compliance obligations.
Welding Fume Monitoring
Welding fumes contain a mix of metal oxides and gases that can pose serious respiratory risks. We monitor welding fume exposure to determine compliance with relevant exposure standards and recommend appropriate engineering and PPE controls.
Heat Stress & Vibration Exposure Assessment
Heat stress and hand-arm or whole-body vibration are measurable, quantifiable occupational hazards in outdoor, industrial, and machinery-heavy workplaces. We assess exposure against relevant standards and provide practical control recommendations.
Mould & Biological Testing
Mould contamination affects both indoor air quality and worker health. We undertake mould and bioaerosol testing, with laboratory analysis conducted by independent NATA-accredited laboratories, to identify contamination and support remediation decisions.

Frequently asked questions
Occupational hygiene testing is the measurement of workplace hazards — airborne contaminants, noise, and other physical exposures — to determine whether they exceed relevant exposure standards, supporting a PCBU’s legal duty of care under WHS law.
Calibrated air sampling equipment is attached to a worker during their normal work shift to capture real-world exposure data, which is then sent for laboratory analysis and compared against the relevant exposure standard.
Under the WHS Regulation 2017 (NSW), PCBUs must ensure exposure to airborne contaminants and other measurable hazards does not exceed workplace exposure standards. Testing is the standard way to demonstrate this obligation is being met.
Yes — our services also cover workplace noise, ergonomics, indoor air quality, silica dust, welding fumes, heat stress, vibration, and mould.
Yes, all laboratory analysis is conducted through NATA-accredited laboratories.
Costs depend on the number of workers being monitored, the hazard types being tested, and site complexity. A fixed-fee quote is provided after an initial consultation.
