RPE Face Fit Testing - Qualitative Tests

Ensuring respiratory protection with The First Principle

In the United Kingdom (UK), face fit testing is a crucial process that helps ensure the effectiveness of respiratory protective equipment (RPE) in preventing the inhalation of harmful airborne substances. It is a legal requirement under the Control of Substances Hazardous to Health (COSHH) Regulations and the Control of Asbestos Regulations, which aim to protect workers from hazardous substances in the workplace.

A technique called face fit testing is used to evaluate how well the RPE's facepiece seals against the wearer's face. In order to reduce the possibility of contaminated air escaping into the mask and being inhaled by the wearer, the test's goal is to make sure the RPE forms an airtight seal. This is crucial when dealing with potentially harmful compounds, such as airborne dust, gases, and particles, which can result in major health problems, such as cancer and respiratory disorders.

Employers have a legal responsibility to provide suitable RPE to workers who are exposed to hazardous substances, and to ensure that the RPE fits properly and provides effective protection. Face fit testing is a crucial step in this process, as it verifies that the RPE is compatible with the wearer's face shape and size, and that it is worn correctly to achieve a secure seal.

Who needs Face Fit Testing?

It is essential for any wearer of tight-fitting RPE to ensure it is adequate and suitable. RPE should be selected correctly for the task, and all users must be trained in the correct use of the equipment. Reusable RPE should also be inspected and maintained at required intervals. In the case of tight-fitting respirators, wearers should have a face fit test carried out.
