Development of Test Methods for Single Use Organic Vapor Respirators at the Bendix Corporation, Launch Support Division, Cocoa Beach, Florida.
NIOSH 1978 Jul:65 pages
A certification testing program for single use valveless organic vapor respirators is described. The effects of humidity, breathing rate, temperature, type of sorbent, solvent vapor and solvent concentration on respirator performance were evaluated. Fifteen different solvents were tested at concentrations of 100, 250 and 1,000 parts per million. Breakthrough times were determined. In all tests, the maximum breakthrough never exceeded 20 percent of the input concentration. The author suggest that the 20 percent breakthrough limit be used as the basis for a certification test method for single use valveless organic vapor respirators. Further research is suggested to establish equilibrium data for the respirator under all possible conditions of use.
