Centro de Documentacion de Fundación MAPFRE - A Feasibility study of quantitative respirator fit testing by controlled negative pressure

Notas: Sumario: The feasibility of using a direct measure of respirator leakage flow rate as a quantitative index of respirator face seal fit has been explored through the use of a new controlled negative pressure method. The method is based on exhausting air from a temporarily sealed respirator facepiece at a rate sufficient to generate and then sustain a constant negative pressure inside the facepiece while the wearer holds his breathRegistros relacionados: En: American Industrial Hygiene Association journal. - Akron, Ohio. - Vol. 52, nº 4, April 1991 ; p. 172-176Materia / lugar / evento: Higiene industrial Contaminantes químicos Equipos respiratorios Mascarillas autofiltrantes Máscaras Métodos de control Tests Otros autores: Eroh, Martin P.
