| Abstract |
Equations that predict the magnitude of the effect of lung retention and respirator dead space on average inhalation concentration and other related quantities were developed, tested and applied. The equations were validated by numerical simulation and experimental measurement with a respirator on a mannequin connected to a breathing machine. Experimental data verifying the applicability of the equations are presented, as are applications of the equations and procedures to various types of respirator performance measurements and to a predictive respirator performance model. Graphs give correction factors, which in all cases were less than 2. Under typical conditions of workplace protection factor measurement with half-mask respirators, average inhalation concentration will be 105% to 125% of full-cycle average concentration. |
