There has been a huge increase in demand for P2 respirators for use against airborne pollutants with recent events in Australia such as bushfires and the COVID 19 Pandemic. Many more non-compliant respirators are becoming available.
The Australian Institute of Health & Safety has released this media statement https://www.aihs.org.au/news-and-publications/news/media-release-urgent-call-national-register-respirators-protect
A coalition of workplace health and safety related organisations across Australia and New Zealand, and the ACTU called today for the urgent establishment of a register for approved respirators (aka face masks). The group describes the presence of non-compliant, fake and faulty disposable masks as an immediate threat to the health and safety of workers.
