Abstract:

In the battlefield situation, soldiers must don their protective masks when a chemical or biological threat is suspected Figure 1. Once the soldier had donned his mask, proper fit is essential for maximum respiratory, eye, and skin protection in contaminated environments. Therefore, the assurance of proper fit after mask donning is of primary importance. In the laboratory evaluation of the protective masks, the leakage of a challenged aerosol is quantitatively measured using very sensitive detection instrumentation. A study was conducted to determine the feasibility of developing a field expedient method to test the integrity of a face mask. Cursory observation indicates that tobacco smoke odor can provide a protection factor on the order of 3000 which represents a potentially significant improvement over the protection factor provided by isoamyl acetate banana oil, which is of the order 500 or less.
