AS/NZS ISO 16975 – Understanding the Updated Respiratory Standard
The AS/NZS ISO 16975 series is the latest standard governing respiratory protective devices (RPDs) in Australia and New Zealand. The 2023 updates provide clearer guidance for selecting, using, and maintaining respirators in the workplace, ensuring worker safety aligns with international best practice.

Key Changes in AS/NZS ISO 16975.3:2023
Enhanced Fit Testing Requirements: The standard now emphasizes the importance of regular fit testing to ensure respirators provide adequate protection. It outlines both qualitative and quantitative fit testing procedures.
Focus on User Comfort and Safety: Updated guidance helps workplaces select respirators that are comfortable, suitable for the work task, and properly maintained, reducing the risk of improper use.
Integration with Respiratory Protection Programs: Employers are encouraged to implement comprehensive programs, including training, inspection, maintenance, and record-keeping.
Adaptation to New Respirator Technologies: The standard now accounts for powered air-purifying respirators (PAPRs), loose-fitting hoods, and other modern RPD types, clarifying requirements for both tight- and loose-fitting devices.
Clearer Selection Guidance: The updates provide practical advice for choosing respirators based on hazards, workplace environment, and worker characteristics.
