Face fit testing or respirator fit testing is an important range of tests undertaken to ensure that tight-fitting respirators fit the user correctly. It ensures respirator masks are working properly to provide the highest level of protection to the wearer. Respirator fit testing is generally conducted for two reasons:
1. To ensure the user can put the mask on correctly, as per the manufacturer’s guidelines.
2. To guarantee that the seal on the face is adequate and the respirator is suitable for the user.
Regulations and guidelines across several industries are already in place which recommend face fit testing is carried out annually, or more often if recommended by the respiratory mask manufacturer’s policies.
Testing should also be carried out as outlined in Australian Standards AS/NZ 1715:2009 Selection Use and Maintenance of Respiratory Protective Equipment (half face, full face and disposable masks).
Quantitative (QNFT) testing is the highest standard of face fit test which can be implemented, as it provides an accurate and numerical result, based on data. Any leakage is measured around the face seal of a respirator and provides a ‘fit factor’ number. Each respirator type will have a minimum fit factor which must be achieved to pass the test.
