Abstract: This study was a quick assessment of the Mark V CBR respirator for its fit factor and physiological effectiveness using two volunteer subjects. The assessment included tests for fit factor, vision, and carbon dioxide buildup during exercise. Having been manufactured in 1984, the ability of this respirator to provide adequate nuclear, biological, and chemical and hazardous materials protection for civil authorities was questionable. Three of these respirators still in their original packages were supplied for testing. The assessment indicated that the masks should be discarded or used only for training.
