OBJECTIVE: This study addresses methods for training respirator users, particularly when occupational health professionals are not immediately available. METHODS: A randomized trial compared three training methods-printed brochure, video, and computer-based training-for two respirator types (filtering facepiece and a dual-cartridge half facemask). Quantitative fit testing (PortaCount) measured the effectiveness of training. The study included 226 subjects. RESULTS: For both respirator types, video was significantly superior to either print or computer-based training methods. Conclusions were consistent, whether determined by average fit factor (analysis of variance), log-transformed fit factors, or the number of users in the lowest quartile of achieved fit. CONCLUSIONS:Video training for proper respirator use can be effective when direct training from an occupational health professional is unavailable. These methods are particularly relevant to "rapid rollout" situations, such as natural disasters, epidemics, or bioterrorism concerns.
