Abstract
The feasibility of using Use Test protocols proposed by the US Bureau of Mines for the human testing of self contained breathing apparatus (SCBA) was evaluated. Recent studies on the physical characteristics of SCBA users and metabolic rates of SCBA users were reviewed. Proposed SCBA Use Test protocols were described. Four different 60 minute closed circuit self contained self rescuers and a 4 hour closed circuit rescue apparatus were used in the study. Subjects included seven men, ages 18 to 35 years. They were placed into three body weight groups, and different treadmill grades were used for each category. For Test 1, an oxygen consumption (VO2) of 1.35 liters/minute (l/min) was used. For Test 2, four of the respirators were tested for 1 hour and one was tested for 4 hours. Test 2 was also performed without wearing a respirator for 1 hour. Using the multiple work rate Test 2, there was no difference in duration for the body weight categories. The authors conclude that the use test protocols could be used as a basis for a revision of the current Man Tests for SCBA performance evaluation.
