A STUDY OF THE EFFECTIVENESS OF THE XM-41 FILTER FOR USE WITH HAZARDOUS CHEMICALS

The XM-41, a carbon adsorbent-containing filter, is to be used as part of a butyl rubber suit to protect personnel in a cleanup operations of hazardous chemical spills. The filter was developed at the Aberdeen Proving Grounds, MD for protection against toxic chemical agents, but its effectiveness against commercial chemicals was not known. In this study, criteria were developed by theoretical and experimental means to evaluate its effectiveness against 900 chemicals when the vapor concentration was 2 volume percent or saturated vapor, whichever was lowest. Stipulated service time was 120 minutes. The determining factor was the vapor pressure. Those organic chemicals with vapor pressures less than 0.25 mm Hg gave service times longer than 120 min and those with vapor pressures more than 1.1 mm Hg gave service times less than 120.
