Workplace indoor air quality assessment
Under the Health and Safety at Work Act 2015, a PCBU must eliminate or minimise risks to health so far as is reasonably practicable, and the air inside the workplace is part of that duty. Where a substance has a WorkSafe Workplace Exposure Standard (WES), we measure against it. Where it doesn't, as with CO2, humidity and general ventilation, we compare the results with ASHRAE 62.1 and WHO guideline values. Either way, you get a clear picture of the air at work and a list of anything that needs fixing.
A MAIOH-qualified occupational hygienist carries out the sampling, using calibrated instruments that log readings on site and standard sampling media. VOC and particulate samples are analysed by IANZ-accredited partner laboratories.
What we test
- Volatile organic compounds (total VOCs, plus individual compounds where relevant)
- Inhalable and respirable particulates (PM2.5, PM10)
- Carbon dioxide (CO2), which shows whether ventilation is adequate
- Relative humidity and temperature trends
- Carbon monoxide (CO) where combustion sources are present
- Airborne mould spores, where there is a reason to suspect mould, analysed in our own laboratory
Workplace mould as part of an IAQ assessment
If mould is suspected at work, such as after a leak or in a damp storeroom or musty office, we add spore-trap sampling to the same visit and include it in the same report. The mould samples are analysed in our own laboratory.
Mould in a home or rental property? That is a different service. Residential mould air testing, surface sampling and moisture investigation are handled under Mould Assessments →
Smoke residue after a fire? Soot, ash and char on surfaces and in the air are measured by our laboratory under Fire Residue Testing →
