Centro de Documentacion de Fundación MAPFRE - Quantitative respirator fit testing : dynamic pressure versus aerosol measurement

Notas: Sumario: A noninvasive, fast, inexpensive new fit testing method has been invented which relates the slope of the pressure decay inside a respirator during breath-holding to the fit of the respirator on the wearer's face. The dynamic pressure test has been compared with the conventional aerosol test at different leakage levels. The results of this comparison show that the sensitivity of the dynamic pressure test is similar to that of the aerosol test. The pressure test, however, is independent of leak site and probe location and can be performed on respirators before and after their useRegistros relacionados: En: American Industrial Hygiene Association journal. - Akron, Ohio. - Vol. 49, nº 10, October 1988 ; p. 492-496Materia / lugar / evento: Higiene industrial Contaminantes químicos Aerosoles Equipos respiratorios Máscaras Tests Métodos de análisis Estudios comparativos Otros autores: Willeke, Klaus
