Abstract : This report describes the results of an investigation to evaluate, by means of chamber tests, the effect of concentration of H vapor and the effect of time of exposure on the protection afforded by 1-1/2 layer CC-2 impregnated clothing. As a result of this investigation it has been concluded that: (a) within the range of 10-100 gamma H/1., the protection is relatively independent of the concentration of agent, and (b) the protection is primarily a function of the time of exposure. It was indicated that, for successive daily H vapor exposures, men wearing 1-1/2 layer CC-2 impregnated clothing are capable of tolerating a total of 4 to 8 exposure hours, irrespective of agent concentration within the range of 10 to 100 gamma H/1. This time of exposure may be incurred as a continuous exposure or as intermittent daily exposures of any duration from 1 to 4 hours. It was also indicated that under the most adverse conditions studied in these series of tests (i.e.; low concentration of H vapor and long time of exposure), a CT of approximately 3000 is the upper limit for which 1-1/2 layer CC-2 clothing may be expected to provide adequate protection.
