Which respirators need fit testing?
WorkSafe WA states that all tight-fitting respirators need to be fit tested — including disposable and reusable half-face respirators, full-face respirators and tight-fitting powered air-purifying respirators (PAPRs).
When to fit test
- before the respirator is first used
- when a different make, model or size is issued
- when the wearer's face changes — for example significant weight loss or gain, or dental work
- repeated regularly, at a frequency based on your risk assessment
Qualitative or quantitative?
Both methods are recognised under AS/NZS 1715:
- Qualitative — a pass/fail test based on the wearer tasting or smelling a test agent. Suitable for half-face respirators only.
- Quantitative — uses equipment to measure leakage into the respirator. Suitable for all tight-fitting types.
Facial hair
Wearers must be clean-shaven where the respirator seals against the face, or have only facial hair that does not interfere with the seal or valve. Where that is not possible, a loose-fitting powered hood or helmet may be an option.
Who can do it, and records
Fit testing must be done by a competent person — this can be a manufacturer, supplier or consultant. Keep a record of the test type, respirator make, model, size and style, the date and the result, and give the worker a fit test card.
Practical tips
- Match the respirator to the hazard first — fit testing does not fix the wrong type of filter.
- Keep a fit test register and flag when a different model is purchased.
- Combine fit testing with training on fit checks, storage and filter change-out.
