Both of the Quantitative and Qualitative objectives are to recreate a working environment and to test the Respiratory Protective Equipment (RPE). RPE must fit the wearer correctly leading to a good seal whilst they are working. The candidate will have to perform some simple exercises whilst wearing the selected face piece. These will be Normal & Deep Breathing, Head side to side, Up/Down, counting Aloud and Bending Over. These are the times when the RPE may fail & leak!
These methods, during a series of test exercises, use the wearer’s sense of taste to detect face seal leakage of test agent. Qualitative tests are subject to problems with sensitivity, lack of objectiveness and inability to provide a numerical result. For these reasons Qualitative tests can only be employed for fit testing FFP’s (disposable) and half masks.
