An evaluation of organic vapor respirator cartridges and canisters against vinyl chloride.
Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, DHEW (NIOSH) Publication No. 75-111, 1974 Oct; :1-29
A study was made of four types of approved organic vapor respirator cartridges and four types of approved front or back mounted organic vapor gas mask canisters. Several concentrations of vinyl-chloride (75014) were used to test the cartridges. The gas was mixed with air and passed through the cartridges and measured downstream until breakthrough occurred. The tests showed that organic vapor respirator cartridges had sufficient life for 20 minutes service at concentrations less than 50 parts per million(ppm). Organic vapor front or back mounted gas mask canisters have sufficient life for 100 minutes service at concentrations less than 100ppm. Facepiece leakage is expected to be 10% for a half mask respirator and 1% for a full facepiece respirator. A final decision regarding the use against vinyl-chloride must be based on the allowable ceiling exposure for vinyl-chloride adopted. Recommendations were made for the use of organic vapor respirator cartridges and gas mask canisters in atmospheres containing vinyl-chloride gas, based on expected service life and facepiece leakage.
