About This Course

Face Fit Train the Tester (Qualitative)


To understand face piece options and learn how to fit a face piece appropriately.  To be aware of when a mask may need to be re-fitted in the future.

Who Should Attend? 

This course is suitable for anyone who needs to carry out a qualitative face fit test on employees (sometimes called the taste test) such as managers, health and safety managers, supervisors, site agents and project managers.


Delegates will be able to undertake qualitative face fit testing on their work force, having an understanding of the choice of face piece, how to set up the test, interpret failures and troubleshoot problems.

A multiple choice test

Training is in accordance with HSE INDG 479 and is conducted by a fully accredited trainer. 



Quantitative tests can be used to fit test all types of tight-fitting masks including FFPs (disposable), and half and full-face masks. Quantitative tests can give an objective assessment of facial fit and provide a direct numerical result called a Fit Factor. The most widely used quantitative method for RPE fit testing is the Particle Counting method, a title ascribed to the TSI Portacount.

The Portacount measures the number of ambient particles inside and outside a face piece and proves a numerical result which is the ratio of the two over a given test period. For more details on test exercises and pass levels go to the HSE INDG 479 protocol. Testing can be conducting based on a half day’s testing rate (3-10 tests) or full day’s testing rate (10-16 tests). A certificate of the face fit test results is provided for each test.




Qualitative tests rely on a wearer’s subjective assessment of face seal leakage. These methods, during a series of test exercises, use the wearer’s sense of taste to detect face seal leakage of the test agent. Qualitative tests are subject to problems with sensitivity, lack of objectiveness and inability to provide a numerical result. For these reasons, qualitative tests can only be employed for fit testing FFPs (disposable) and half masks.

Length of time taken is dependant on the number of candidates to be tested.
