Final Report, Organic Vapor Respirator, Service Life Prediction.
The service life of an average organic vapor respirator cartridge was estimated for 231 compounds listed in 29 Code of Federal Regulations (CFR) 1910.1000. The study was requested by NIOSH to aid in determining substances with possible marginal service lives for laboratory testing. Calculations were performed on a computer using the Dubinin equation to determine adsorption capacity and the modified Wheeler equation to estimate service life. A computer print out tabulation provided the threshold limit value, density, vapor pressure, adsorption capacity, and predicted cartridge service life for each compound. Fifty additional compounds are listed for which cartridge service life was not estimated because of insufficient density and vapor pressure data. The author suggests that the estimates of cartridge service life may be helpful to industrial health professionals in administering industrial respiratory programs.
