Title Particle release from respirators, Part II: Determination of the effect of tension applied in simulation of removal
Bibliographic information Jan. 2011, Vol.8, p.10-12. Illus. 2 ref.
Abstract This study evaluated the potential for disposable filtering facepiece respirators (hereafter termed masks) contaminated with 1μm particles to release particles as a result of lateral tension applied to the mask. The lateral tension was designed to simulate the removal of a contaminated mask from a user's head. Four brands of filtering facepieces were loaded with approximately 20 million 1.0μm polystyrene latex microspheres. The respirators were then placed in a test chamber and subjected to lateral tension between 17.8-26.7 for 1-2sec. Findings suggest that neither mask type nor loading condition affects particle release. This supports the hypothesis that when filtering facepiece respirators are properly removed from the head they will not release a significant number of particles. See also ISN 111322.
