RPE face-fit testing checks that the seal between tight-fitting RPE and the wearer’s face is satisfactory. Leakage via the face seal can occur if the RPE is the wrong size or shape for an individual’s face. This will result in inward leakage of the external air and potential exposure to hazardous substances which may be detrimental to health.
Quantitative RPE face-fit testing measures the airborne particulates outside and inside the RPE, simultaneously. By dividing the particulates in the air measured outside the RPE by the number detected inside, a fit factor is derived.
The HSE require that filtering face pieces (e.g. FFP1, FFP2 and FFP3) which are also known as ‘disposable’ masks and half masks (original) require a fit factor of at least 100. For full-face RPE a fit factor of above 2000 is required.
Face-fit testing of employees issued tight-fitting RPE is a requirement in the Approved Code of Practices (ACOP) of the UK COSHH, CLAW and COA Regulations. Detailed guidance on RPE face-fit testing is provided in the HSE document – OC 282/28.
