Whether you’re spraying paint or applying powder coating, you’re working in an environment filled with airborne hazards — fine particulates, solvent vapours, or toxic isocyanates. Without proper respiratory protection, these substances can seriously harm your lungs and overall health.
In Australia, the safe use of respirators is not just good practice — it’s governed by AS/NZS 1715 and AS/NZS 1716, which cover the selection, use and maintenance of respiratory protective equipment. Here’s how to do it right.
-
Identify the Hazard First
Different coatings release different contaminants:
- Spray painting with solvent-based paints often exposes you to VOC’s (volatile organic compounds), including dangerous isocyanates found in two-pack paints.
- Powder coating releases fine dust particles during application and clean-up.
You need respiratory protection that matches the specific hazard type — vapour, dust, or both.
-
Choose the Right Respirator for the Job
Australia’s standard for respirators (AS/NZS 1716) categorises them into two key types:
Air-Purifying Respirators (APRs)
These filter out contaminants from the air:
- For liquid spray painting, use a half-face or full-face respirator with: A1 or A2 cartridges (for organic vapours) / P2 or P3 filters (for fine particulates and mists).
- For powder coating, use a P2 or P3 particulate filter, which is compliant with AS/NZS 1716 standards for dust and fume protection.
Supplied-Air Respirators (SARs)
Required when working with isocyanates or in confined or poorly ventilated spaces. These systems deliver clean air from an external compressor or air cylinder and are considered the gold standard for high-risk spray work.
Note: Disposable masks (P2/N95 style) are not suitable for spraying paint unless explicitly rated and fit tested. Avoid relying on them unless your work is very low risk and strictly dry powder-related.
-
Fit Testing Is Mandatory Under AS/NZS 1715
A respirator must form an airtight seal with your face to work effectively. Under AS/NZS 1715, employers are required to:
- Conduct initial fit testing before first use (qualitative or quantitative)
- Ensure the wearer is clean-shaven in the sealing area
- Conduct seal checks each time the respirator is worn
Poor fit = Poor protection. If you can’t achieve a proper seal, you’re better off not working until you can.
-
Maintenance and Filter Changes
- Cartridges and filters should be changed regularly — frequency depends on manufacturer guidelines, exposure levels, and air quality.
- Clean the mask after every shift using mild detergent and store it in a clean, airtight container.
- Inspect before each use: check valves, straps, facepiece, and connection points for any signs of damage.
Pro tip: Keep a maintenance log as required by AS/NZS 1715, especially in workplaces where respirator use is part of regular operations.
-
Don’t Forget the Rest of Your PPE
A respirator is only one part of your personal protective equipment (PPE). For full compliance and safety:
- Wear eye protection (AS/NZS 1337.1 rated safety goggles or a full-face respirator)
- Use disposable coveralls to reduce contamination and secondary inhalation
- Make sure your work area is ventilated to AS/NZS 1668 standards, or use local exhaust ventilation systems
Summary Checklist – Are You Compliant?
✅ Correct respirator type selected (AS/NZS 1716)
✅ Fit tested and clean-shaven (AS/NZS 1715)
✅ Filter type matches hazard (A1/P2, A2/P3, etc.)
✅ Maintenance and change-out schedule followed
✅ Ventilation and PPE in place
Conclusion
If you’re painting or powder coating in Australia, using the correct respirator the right way is non-negotiable. Complying with AS/NZS standards not only protects your health but also keeps your business safe from legal risks. Choose the right mask, ensure proper fit, maintain it regularly, and don’t cut corners.
