Where Are We In Respirator Quantitative Fit Testing - A Critique of QFT Systems and Their Uses.
NIOSH 1980 Sep:411-434
Respirator quantitative fit testing systems and their uses are discussed. Various types of laboratory and field testing systems developed since 1960 are reviewed. The status of efforts by the Los Alamos Scientific Laboratory, OSHA and others to develop a standard for quantitative fit testing systems is reviewed. Methods used to determine the protection factors for respirators and quantitative fit testing data are discussed. A proposed regulation requiring quantitative fit testing on wearers before a standard testing method is adopted is discussed. Respirator defects and use problems which may be revealed by quantitative fit testing are identified. The author concludes that sufficient data exist to justify the use of quantitative fit testing systems with anthropometric panels and that the required use of quantitative fit testing systems in some OSHA health standards is not justified without adoption of a standard system.
