Fit factor studies for an air-supplied blouse (blouse) and an air hood respirator (air hood) were conducted by Lawrence Livermore National Laboratory. Nine test subjects were used to test the blouse. Three subjects were used to test the air hood. Exercises conducted in the test chamber included touching toes, raising both arms overhead, squatting, twisting at the torso while holding a rod, and running in place. Both the air hood and blouse were tested with 8 ft3/min air supply. Both respirators were worn in a test chamber. The blouse provided a fit factor of greater than 40,000. The air hood, for nearly all tests, also provided a fit factor greater than 40,000 when worn correctly. Fit factors were also measured for improperly worn air hoods.
