The purpose of this paper is to discuss the development of an innovative self-contained self-rescuer (scsr) donning method, and to assess the impact of differing instructional strategies used to teach this method. The method is a generic procedure that is applicable to the four scsr models currently being marketed in the United States. It consolidates the procedural tasks into three critical steps and three secondary steps. The "3 + 3" method has been shown to cut donning times in half and to significantly reduce errors made by trainees. The strategies used to teach this method were a live demonstration, a structured lecture, and a computer- based format. It was found that delivery strategy makes little difference as long as the content is presented thoroughly and systematically and followed up with hands-on experience. The question of how often, and at what level, miners should be retrained has not yet been answered.
