OSHA requires that all respirators with tight-fitting facepieces be fit tested. This includes positive pressure masks like PAPR and SCBA. It does not matter how the air gets into the mask. If it is a tight-fitting facepiece, i.e. the performance of the respirator depends on a tight seal between the mask and the user’s face, then OSHA requires fit testing. This represents a new requirement mandated in OSHA’s Respiratory Protection Standard that was released on January 8, 1998. Refer to Application Note ITI-056 Respirator Fit Testing Highlights for OSHA Respiratory Protection Standard 29CFR1910.134 for information regarding the fit testing requirements of the new OSHA standard.
