Respirator Fit Testing

Qualitative Fit Testing

Qualitative fit test (QLFT) is a type of respirator fitting test that relies on the user’s sense to determine whether there is any leak in the seal of the respirator to his/her face. The test procedures include testing at a sensitivity level that establishes whether the user would be able to sense the presence of the test agent by taste, smell or cough while wearing the respirator.

Quantitative Fit Testing

Quantitative Fit Test (QNFT) is a type of respirator fitting test that numerically evaluates respirator fit, measuring the leakage into the respirator. It compares the respirator leakage with ambient concentrations of the test agent.  This test is used where higher respirator fit factors are essential for safety.  We would employ a Porta Count 8038 unit for this fit testing.

Elite Safety Services Inc. would, in advance, require the SCBA or APR mask style in order to ensure that the proper adapters are available prior to site arrival.
