It is the suitability of the respirator for use in ensuring your safety and health that is under test.Before the testIt’s important that you have not eaten or drunk anything or smoked for 15 minutes before testing. This can desensitise you to the taste of the Bitrex test agent.About the Bitrex test substanceBitrex is a non-toxic neutral substance which is used in this type of testing for it’s strong bitter taste that is easily detectable. Drinking water after the test will quickly remove the taste.Taste Sensitivity Screening and TestingThe testing starts with a screening procedure wearing the testing hood but without a mask to ensure that you can detect the bitrex test agent. Then the test itself is performed where the testing hood is worn over a fitted mask and you will be asked to make several different actions with your head. These are designed to simulate the movements of the head during work which can cause inward leakage if there is not a good seal. It’s important to breathe through the mouth at all times during the testing so that it is possible to detect the taste of the test agent if it is present inside the mask.Testing the test procedureFor testing the test procedure itself a certain number of tests may be done with water as a test agent rather than Bitrex.
