National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Organic Vapor Respirator Service Life Prediction.

PB82189739

Publication Date	1981
Personal Author	Smoot, D. M.
Page Count	39
Abstract	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.
