Demonstration: TSI PortaCount Pro Respirator System OSHA Fit Test

New to fit testing with a PortaCount system

The TSI PortaCount Pro system walks you step-by-step through a fit test, so you don't need special training to operate it.

Note: Because the grimace exercise (at 7:17) is done to intentionally break the face seal and make sure the mask reseats itself, this portion of your fit test should result in a failed fit factor. The OSHA protocol includes special provisions for the 15-second grimace exercise, and its fit factor can be excluded before calculating the overall result for your test.
