The Approved Code of Practices supporting COSHH, CAR and CLAW stipulate that tight-fitting RPE (respiratory protective equipment) MUST be fit tested as part of the selection process. This is to ensure that the selected RPE has the potential to provide adequate protection for the wearer. 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 ï ¬ tted correctly to get a tight seal and ensure safety against hazards in the workplace. It is important to remember it is the suitability of the respirator that is being tested. Each kit is suitable for carrying out multiple tests and come packaged in their own sturdy case, all kits come with a FREE Fit Test CD, to help employers understand more about Fit Testing, the requirements and how to carry out tests.
