Qualitative Face Fit Testing

The COSHH Regulations and the associated Approved Code of Practice recommend that the initial selection of tight fitting face pieces should include a fit test.

This is to ensure that the selected RPE has the potential to provide adequate protection for the wearer.

The performance of tight-fitting face pieces depends on achieving a good contact between the wearers' skin and the face seal of the face piece. Inadequate fit will significantly reduce the protection provided.

Any reduction in protection can put the wearers' life in danger or may lead to immediate or long-term ill health.

There are two main reasons for doing Bitrex testing.

 

Firstly, to make sure that the respirator itself is suited for the wearers particular face shape.

Secondly to make sure that the respirator is fitted correctly to get a tight seal and ensure safety against hazards in the workplace. It is important to remember that it is the suitability of the respirator that is being tested.
