Respiratory Fit Testing

If you wear a close-fitting respirator for work that relies on the face seal to achieve the designed protection, then you need to ensure that your respirator has been properly fit tested. This is a requirement of the standard AS/NZS 1715.

Fit testing should be carried out:

  • Before a respirator is issued to ensure the correct size and a proper fit is achieved.
  • Whenever there is a change of facial characteristics or other features e.g. loss of teeth, excessive change in weight, if biological testing shows excessive exposure to contaminants.
  • At least every 12 months.

There are two types of fit tests that are generally used and pH7 can perform both.

Qualitative fit testing:
  • These are fast and easy to perform. However, the test relies on the wearer’s subjective response and as such it’s not as reliable as a quantitative fit test.
  • The wearer will have a plastic hood placed over their head with a respirator fitted and be asked to perform a series of movements and tasks such as breathing deeply, moving their head side to side or up and down. A fine spray that has a distinctive smell and taste will be sprayed into the hood. If the wearer is unable to smell or taste the spray, then a good face seal has been achieved.
Quantitative fit testing:
  • pH7 used the latest PortaCount Fit Tester 8048+ with FitPro Ultra software to accurately measure the efficiency of a respirator at preventing material in the atmosphere from entering the wearer’s breathing zone.
