FIT Tester Training (theory)

The FIT test assessor must be trained in

•selection of adequate and suitable RPE

• examination of RPE and the ability to identify poorly maintained facepieces

•ability to correctly fit a facepiece and perform pre-use wearer-seal checks

•ability to recognise a poorly fitting facepiece

•awareness of external factors that may affect the fit of the facepiece or the fit  test result

•the purpose and applicability of fit testing

•the differences between, and the appropriate use of, QNFT and QLFT methods

The FIT test assessor must be trained in:

•the purpose of the fit test exercises

•preparation of facepieces for fit testing

•how to carry out diagnostic checks on the facepiece and the fit test equipment

•capabilities and limitations of the fit test equipment

•how to perform a correct fit test with the chosen method

•awareness and knowledge of how to prevent and correct problems during fit testing

•interpretation of fit test results

•an understanding of the differences between fit factor, workplace protection factor (WPF),† assigned protection factor and nominal protection factor (NPF)‡

and

•HSE Approved Codes of Practice (ACOPs) and guidance for the face fit testing of RPE
