Respirators range from simple filters like N95 masks for Tuberculosis to Air Purifying Respirators (APRs) to self-contained breathing apparatuses (SCBA). Regardless of the type, respirators need training and maintenance programs as well as verification of appropriate size and fit for the device and users in question.
The Respiratory Protection Standard, 29 CFR 1910.134. It requires a written program for respirator use, medical evaluations of the respirator users, fit testing of respirator models used on potential wearers, and training of the respirator users. The Respiratory Protection Train-the-Trainer program will prepare the attendee to coordinate the respiratory protection program, conduct the training, and perform both qualitative and quantitative fit testing.
