FAQ
Is fit testing required of positive pressure respirators such as SCBAs, powered air purifying respirators (PAPRs), and supplied air respirators (SARs)?
Yes. The standard requires fit testing of the facepiece to check for leakage. The standard allows the employer to conduct the test by using a negative pressure respirator with a facepiece of the same make, model, and size as the positive pressure facepiece, or by temporarily converting the facepiece for the positive pressure apparatus to a negative pressure device and performing the fit test.
