The class of filter will be clearly marked on the filter, filter package, or respirator box. The three categories of resistance to filter efficiency degradation are labeled N, R, and P. The three levels of filter efficiency are 95%, 99%, and 99.97%. The new Part 84 regulation provides for nine classes of filters (three levels of filter efficiency,† each with three categories of resistance to filter efficiency degradation‡). Under Part 84, NIOSH is allowing manufacturers to continue selling and shipping Part 11 particulate filters as NIOSH-certified until July 10, 1998. Until further notice, the Occupational Safety and Health Administration (OSHA) is allowing the continued use of Part 11 particulate-filter respirators. Certification requirements for all other classes of respirators (e.g., chemical cartridges, self-contained breathing apparatus, airlines, gas masks without a particulate filter, powered air-purifying respirators equipped with high-efficiency particulate air filters, etc.) have been transferred to Part 84 without change. The new Part 84 respirators have passed a more demanding certification test than the old respirators (e.g., dust and mist, dust, fume and mist, spray paint, pesticide, etc.) certified under 30 CFR 11 (also referred to as “Part 11”).Ĭhanges in the new regulations involve only nonpowered, air-purifying, particulate-filter respirators. NIOSH has developed a new set of regulations in 42 CFR* 84 (also referred to as “Part 84”) for testing and certifying nonpowered, air-purifying, particulate-filter respirators. This summary presents a brief overview of what the respirator user needs to know about the new categories of particulate respirators certified by the National Institute for Occupational Safety and Health (NIOSH). Thanks to all the workshop participants and many reviewers who helped in completing this document. NIOSH thanks the American Industrial Hygiene Association (AIHA), particularly Anna-Marie DiPasquale, John Meagher, and Tom Nelson, for providing the facilities and organizing the joint AIHA/NIOSH technical workshop (July 1995). We thank Judy Hudnall and Dick Carlson for art work and cover design, Anne Hamilton for editing, and Diane Manning for preparation of the manuscript and the camera-ready copy. Technical review and assistance were provided by Roland Berry Ann, Nancy Bollinger, Donald Campbell, Bryan Hardin, Linda Martin, Richard Metzler, Ernest Moyer, Robert Mullan, and Laurence Reed. This document was initially drafted by Jeff Bryant and Walter Ruch. Occupational Safety and Health Administration National Institute for Occupational Safety and Health workers who wear particulate filter respirators.ĭirector, National Institute for Occupational Safety and HealthĬenters for Disease Control and Prevention Abbreviations Abbreviations APF We believe this information will help protect the health and lives of U.S. We greatly appreciate the assistance of respirator manufacturers and others in making this information available to all employers and respirator program managers. This guide was designed to explain the new regulation and to provide valuable information for selecting and using the new respirators certified by NIOSH. These new respirators also provide significant cost savings: Estimates indicate that the health care industry alone will save millions of dollars as a result of this new generation of practical and efficient respirators. The respirators certified under this new regulation are tested under much more demanding conditions, and they provide increased worker protection. In June 1995, the National Institute for Occupational Safety and Health (NIOSH) updated and modernized the Federal regulation for certifying air-purifying particulate respirators.
