If the entire test is completed without the test person detecting the bitter taste of Bitrex
®
,
the test is passed.
If the test person detects the bitter taste at any point the test is failed and should be
stopped. The test can be repeated.
Sometimes test persons are not sure if they taste something. In this case finish the test
and at the end ask the test person to lift the mask. The test person will now taste Bitrex
®
and give a clear answer if he/she has really detected Bitrex
®
during the test.
5.1 Repeating the test
Before retesting a minimum 15 minute waiting period must be observed to allow the
taste of the test agent to be removed completely. Offer the test person a drink of water.
Both the sensitivity test and fit test should be repeated.
Ideally, the test is performed on the next day. For some people it takes two hours and
longer until they loose the Bitrex
®
taste.
If the second test fails, repeat test with another size and/or model of Moldex mask.
Before restarting the test it is important to review the fit of the mask for any obvious
failures.
