What is the reason for fit testing respirators?
There are two primary reasons for performing fit tests on respirator wearers—a) Verification of training. After the individual has received respirator training, a fit test is performed to make certain that he/she has truly learned how to properly put on and wear a respirator without assistance. b) Sizing. It is important to make sure that the respirator issued to the individual is capable of providing protection when worn properly– i.e., it is the right size. Refer to TSI Applications Note ITI-031 Training is the Key to a Good Fit Test Program for some insight on this issue.
