An Evaluation of Organic Vapor Respirator Cartridges Against Vinyl Chloride,

摘要

The service lives of four types of approved organic vapor respiratory cartridges and four types of approved front or back mounted organic vapor gas mask canisters were determined relative to several concentrations of vinyl chloride. Various mixtures of vinyl chloride gas and air were passed through the cartridges and canister,and the downstream concentration was monitored until breakthrough time conformed to adsorption theory. Brief investigations indicated service life increased at low humidities and decreased at high humidities. Recommendations are make concerning 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.
