Naval Research Laboratory Industrial Chemical Analysis and Respiratory Filter Standards Development
Abstract
Presented here is a comprehensive assessment of the high priority chemical list developed by the NRL-ICA. The purpose of this assessment is three-fold. First, the CBA approach, developed by NRL, is tested by examining the filter behavior against a number of chemicals to determine if the NRL approach resulted in the correct selection of the high priority representative chemicals. Second, using this list, as well as analysis of DOT transport regulations for rail cars, and detailed chemical reactivity studies, atmospheric release modeling is performed for each chemical to determine appropriate challenge levels and required capacities at specific distance and for specific durations form the release of an industrial chemical. These results, as well as the results of the CBA, are also compared to both the NIOSH classification scheme, and the NIOSH list of chemicals. Thirdly, using performance curve data, the performance of Impregnated Carbon will be estimated using the new NRL-CA capacity requirements. This will then be compared to single challenge point data for new filter media, ZZAT. Additionally, how these filter materials are expected to perform at different breathing rates is also assessed.
