Respirator Fit Testing
Respirator fit testing for silica, asbestos, and aerosol risks — supporting site safety and audit readiness.
Why Fit Testing Is Legally Required
Under the WHS Regulation 2017 and the Code of Practice for Managing Risks of Respirable Crystalline Silica, all PCBUs must ensure that tight-fitting respirators (e.g. half-face or full-face P2 masks) are fit tested for each worker before use, and again at least annually, or when:
A new respirator model is introduced
A worker’s facial features change (e.g. weight gain/loss, dental work, facial injuries)
There are issues with fit, performance, or facial hair interference
Fit testing verifies that a mask forms an effective seal to the wearer’s face — ensuring that hazardous particles can’t bypass the filter and be inhaled.
Our Fit Testing Services – Fast, Compliant & On-Site
We use quantitative fit testing methods, considered the gold standard for WHS compliance.
Quantitative Fit Testing (QNFT)
We use quantitative fit testing technology, which measures the concentration of ambient particles outside and inside the respirator while the wearer performs a series of controlled movements and breathing exercises. This provides a numerical fit factor that must meet or exceed a pass threshold (typically ≥100 for half-face masks).
We test all major brands and models, including 3M, Sundström, CleanSpace, Honeywell, Scott Safety, and more — and can help confirm whether your existing masks are compliant.
Testing Inclusions
Each fit test includes:
Pre-test assessment of the respirator type and condition
Education on donning, seal checks, and maintenance
Real-time fit factor results and pass/fail notification
Certificate of fit test for site files and SafeWork inspection readiness
Record-keeping and reminders for re-testing due dates
Testing can be done at your site (toolbox meetings, project sheds, depots) or at one of our local locations — with flexible group bookings available.
Who Needs Fit Testing?
Fit testing is required for anyone using a tight-fitting respirator in a regulated or high-risk work setting, including:
Construction and demolition workers (e.g. for silica or asbestos risk)
Civil, rail, and infrastructure crews
Manufacturing and processing plant staff
Remediation contractors and hazardous material workers
Plumbers, electricians, carpenters, and other tradespeople
Health and aged care workers using reusable respirators or powered air units
Employers must keep a record of fit test results as part of their WHS system.

Frequently Asked Questions (FAQ) – Respirator Fit Testing
Q: Is respirator fit testing required by law in NSW?
Yes. Under the WHS Regulation 2017 and applicable Codes of Practice (e.g. for silica and asbestos), anyone using a tight-fitting respirator must undergo fit testing before first use, and at least annually. This applies to half-face, full-face, and powered air respirators with a tight seal. Employers (PCBUs) must keep a record of fit test results.
Q: What is the difference between qualitative and quantitative fit testing?
Qualitative fit testing uses a bitter or sweet-tasting aerosol to check for mask leaks. It's subjective and usually only suitable for disposable masks in low-risk environments.
Quantitative fit testing (QNFT) uses electronic particle counting equipment (like a PortaCount®) to provide an objective, numerical fit factor. It’s the preferred method for high-risk industries and required for many WHS-compliant sites.
We provide quantitative fit testing for maximum accuracy and regulatory acceptance.
Q: How long does a respirator fit test take?
A single fit test takes approximately 15 to 20 minutes per person, depending on the respirator type and the wearer’s experience. Group bookings or site-based testing can be scheduled for multiple workers across a set timeframe.
Q: What types of masks can be fit tested?
We test most reusable half-face and full-face respirators, including:
P2 and P3 masks (e.g. 3M 6000 series, Sundström, Honeywell)
Powered Air-Purifying Respirators (PAPRs) with tight-fitting facepieces
Tight-fitting elastomeric respirators used in silica, asbestos, or chemical environments
Loose-fitting hoods (like some PAPR units used in healthcare) do not require fit testing — but must still be used correctly.
Q: What happens if a worker fails the fit test?
If a worker fails, we’ll provide practical guidance on improving the fit — including:
Mask adjustment and donning technique
Trying a different size or model
Managing facial hair or other sealing issues
We can retest on the spot or reschedule after changes are made. A worker must pass a fit test before using the respirator in the field.
Q: How often does fit testing need to be repeated?
Fit testing must be repeated:
Every 12 months, or
If a new respirator model or brand is introduced
After facial changes, such as dental work, weight loss, or scarring
If the worker experiences a change in mask performance or discomfort
We help businesses manage their re-testing schedules and maintain up-to-date records.
Q: Do you offer on-site fit testing?
Yes. We offer mobile, on-site fit testing throughout Sydney, Central Coast, Newcastle, the Hunter, and regional NSW. This is ideal for construction crews, depots, workshops, and project sites — with flexible scheduling and group rates available.
