Fit testing measures the effectiveness of the seal between the respirator and the wearer’s face. It is required for all tight-fitting respirators as per AS/NZS 1715:2009, including:

  • Half face disposable

  • Half face reusable

  • Full face reusable

  • Tight-fitting powered air-purifying respirators (PAPR)

AS 1715:2009 requires all fit testing must be carried out by a competent person and must be conducted:

  • At least once annually.

  • Before wearing a tight-fitting respirator for the first time.

  • Each time a new make or model of respirator is issued.

  • Whenever there is a change in the wearer’s facial characteristics or features which may affect the facial seal (e.g., large weight loss or gain).

Respirator fit testing is conducted in accordance with Australian Standard AS/NZS 1715:2009 Selection, use and maintenance of respiratory protective equipment and ISO 16975-3 Respiratory protective devices – Selection, use and maintenance – Part 3: Fit testing procedures.


We are offering quantitative respirator fit testing for healthcare workers and construction workers who may be exposed to a wide range of airborne contaminants, including COVID-19, asbestos and silica dust. With a team of over ten RESP-FIT accredited fit testers, we are able to provide this service either on-site or at our office based in Oakleigh, accommodating individual tests or testing programmes for large teams.
