Perspiration Poisoning of Protective Clothing Materials. Part I. Experimental Results and Evaluation

Abstract

A protective overgarment material of carbon-impregnated polyurethane foam has been developed by the US Army Natick R&D Command, Natick, Massachusetts. The objectives of the work reported here were to study the dynamics of carbon tetrachloride vapor adsorption, the effect of perspiration poisoning, and methods to alleviate perspiration poisoning for this material. As a reference for further work, a central composite statistical design of experiments was conducted on the carbon-impregnated foam in a vapor test apparatus to study adsorption dynamics. The vapor penetration through the bed was monitored by a gas chromatograph. The work resulted in the development of a mathematical model for the breakthrough time (the time at which the exiting vapor concentration is 5% of the inlet concentration). This model suggests that the breakthrough time varies directly as the number of carbon impregnated foam layers, or bed depth, and inversely as the gas flow rate and inlet gas concentration.
