Do you or your colleagues wear RPE?

19 Jan 2016

Where RPE is used, it must be able to provide adequate protection for individual wearers. RPE can't protect the wearer if it leaks. A major cause of leaks is poor fit – tight-fitting facepieces need to fit the wearer’s face to be effective.

As people come in all sorts of shapes and sizes it is unlikely that one particular type or size of RPE facepiece will fit everyone. Fit testing will ensure that the equipment selected is suitable for the wearer.

Quantitative Face Fit Testing

As stated in HSE OC 282/28 - Quantitative fit testing provides a numerical measure of the fit that is called a fit factor. These tests give an objective measure of face fit. They require specialised equipment and are more complicated to carry out than qualitative methods. Quantitative methods are required for full face masks and can also be used for half masks and FFP (disposable face masks). The methd of quantitative fit testing we use is a portable particle counting device called the TSI Portacount.

Qualitative Face Fit Testing

As stated in HSE OC 282/28 - Qualitative fit testing is a simple pass/fail test based on the wearer’s subjective assessment of the leakage, via the face seal region, of a test agent. These tests are relatively simple to perform and are suitable for half masks and filtering facepieces. They are not suitable for full face masks. The qualitative fit testing method we use is based on the bitter or sweet tasting aerosol
