Respirator Fit Testing

Respirators are donned by personnel and the quality of fit to the person’s face is assessed while performing several activities including deep breathing, talking, and head movement for a duration of 1 minute each. A fit factor is reported for each activity and each person tested to determine pass/fail. OIC utilizes the TSI 8038 PortaCount Pro+ Respirator Fit Tester.
