Título Particle release from respirators, Part I: Determination of the effect of particle size, drop height, and load
Información bibliográfica Jan. 2011, Vol.8, p.1-9. Illus. 15 ref.
Resumen In late 2001, some United States Postal Service workers and a few members of Congress were exposed to anthrax spores. This led to an increased effort to develop employable methods to protect workers from exposure to anthrax. This study evaluated the potential for several types of half-mask respirators to release deposited particles. Four brands of the most commonly used filtering facepiece respirators were loaded with 0.59μm, 1.0μm, and 1.9μm polystyrene latex microspheres and then dropped onto a rigid surface. The load conditions were 10, 20, or 40 million particles, and drop heights were 0.15, 0.76 and 1.37 m. Results of these tests were inconclusive. Part II (see ISN 111323) addresses the release of particles when simulating removal of a filtering facepiece from a wearer's head.
