There are two types of fit testing: qualitative and quantitative. Qualitative is a pass/fail that relies on the respirator wearer's indicating whether he/she can smell, taste, or sense the test agent. Testing agents can be bitrex, saccharin, Isoamyl acetate or an irritant smoke. Quantitative fit testing gives an objective measure of the quality of the seal between the wearer's face and the face piece. A fit factor number is produced.
Simple, safe, and reliable, the Fit Test Kit takes the guesswork out of qualitative fit testing. Using bitrex for example, creates an involuntary response by the wearer. The kit includes fit test solutions, 2 nebulisers, a Tyvex® test enclosure, and instructions. The face fit test kit meets CoSHH requirements as a qualitative fit test for both disposable and reusable respirators.
