Ensuring Proper Fit: The Importance of Face Fit Testing.

Face fit testing is a process used to ensure that a particular piece of respiratory protective equipment (RPE) fits an individual correctly and provides the necessary level of protection. RPE is essential for workers who may be exposed to hazardous substances such as dust, fumes, and other airborne contaminants. The aim is to prevent occupational respiratory diseases from developing which can be detrimental to the individuals health and in some cases life-threatening. Therefore, it is important that the RPE fits correctly to provide the necessary level of protection.

In the UK, face fit testing is a legal requirement for workers who use RPE as part of their work. The Health and Safety Executive (HSE) has published guidelines on the selection, use, and maintenance of RPE, which outline the requirements for face fit testing.

There are two main types of face fit testing: qualitative and quantitative. Qualitative face fit testing involves the use of a test solution, such as a bitter or sweet-tasting solution, which is sprayed into the RPE. The wearer is then asked to detect the taste, and if they can taste it, this indicates that the RPE is not providing an adequate seal around the face.

Quantitative face fit testing involves the use of specialized equipment to measure the amount of air leakage around the RPE. This is typically done using a machine that pumps air into the RPE and measures the amount of air that escapes. The results of the test are used to determine the fit of the RPE and whether it provides the necessary level of protection.

Both qualitative and quantitative face fit testing can be carried out by trained and qualified professionals, such as occupational health nurses or occupational hygienists. The HSE recommends that face fit testing is carried out at least every two years for disposable masks and every year for reusable masks.

In addition to face fit testing, employers in the manufacturing industry should also ensure that they follow other HSE guidelines on the selection, use, and maintenance of RPE. This includes conducting risk assessments to determine the type and level of RPE required, providing training to workers on the correct use of RPE, and regularly maintaining and replacing RPE as needed.

Overall, face fit testing is an important aspect of workplace health and safety in the manufacturing industry, and it is essential for employers to ensure that their workers who use RPE undergo regular face fit testing to ensure that the RPE fits correctly and provides the necessary level of protection.
