What is a Face Fit test

A face fit is carried out to ascertain if a mask to be worn by a user is suitable to maintain a secure seal throughout normal usage. The user will don the mask and undergo a series of simple exercises which simulate normal usage. A particle counter is attached to the mask throughout the test to evaluate particles both inside the mask and the outside (ambient) environment. A computer programme will evaluate the data and ascertain if the RPE is suitable for usage by the wearer.

Asbestos Control Services carry out quantitative face fit testing using a TSI Portacount 8083.
