What is a Face Fit Test?

Face Fit Testing is a method used to ensure that a tight-fitting face-piece matches the person's facial features and seals correctly to the wearer’s face.

There are two types of Face Fit Testing:

Qualitative Face Fit Testing: this is used for half masks and disposable masks to ensure the correct fitting of the face-piece with a series of tests and takes approximately twenty minutes. 

The user has a hood fitted over their head and shoulders, once the face-piece has been fitted.  Then a bitter or sweet substance will be sprayed into the hood through a nebuliser and a series of exercises will be carried out.  If the substance is not tasted, then the Face Fit Test has been successful.  If the substance can be tasted, then the RPE will be adjusted and the test repeated only once.  If the test still fails, an alternative face-piece will need to be selected.

Quantitative Face Fit Testing: this is designed to protect workers from harmful chemicals and dust. At RespiSafe, we use the TSI Portacount, which is the only fit tester that can quantitatively test all types of respirators.

Quantitative face fit tests are suitable for all types of masks, including disposable,  half-masks, and full-face masks.

Each quantitative test involves the candidate wearing a selected mask that is used in their workplace.  This face-piece is connected to the electronic TSI Portacount Face Fit Testing equipment via adapters.  The test counts the particulate in the test room and the particulate within the respirator and calculates, an overall Fit Factor.

A detailed and itemised certificate will be issued for each successful Face Fit Test.

All our Fit Testing personnel are Fit2Fit accredited for the Qualitative and Quantitative fit test methods.
