Face Fit Testing for Masks
What is Face Fit testing?
To comply with the COSHH (Control of Substances Hazardous to Health) Approved Code of Practise (ACoP) employers should ensure that the selected face piece (tight and loose fitting types) is of the right size and fits the wearer correctly.
A Face Fit Test will assess the fit by determining the degree of face-seal leakage of a test agent while the user is wearing the face piece. Respiratory Protective Equipment (RPE)
How does it work?
The nebuliser produces a mist measuring approximately 5 microns. If the wearer tastes the solution during a fit test, the seal has been broken and the wearer has failed the test. If the wearer does not taste the solution during the fit test, the mask fits and this is classed as a pass.
If the wearer fails the exercise they will have to wait 30 minutes before they can be tested again. If the wearer fails twice, then it may be determined that the wearer may require a different model and will be retested in the same way.
Milne Safety can carry out the test either on site or at our premises in Wymondham. Each test takes approximately 15 minutes.
