Additional PortaCount® Quantitative Fit-Testing Protocols: Amendment to Respiratory Protection Standard (12 pages, in English)

OSHA is proposing to add two modified PortaCount® quantitativefit-testing protocols to its Respiratory Protection Standard. The proposed protocols wouldapply to employers in general industry, shipyard employment, and the constructionindustry. Both proposed protocols are variations of the existing OSHA-acceptedPortaCount® protocol, but differ from it by the exercise sets, exercise duration, andsampling sequence. If approved, the modified PortaCount® protocols would be alternativesto the existing quantitative fit-testing protocols already listed in an appendix of theRespiratory Protection Standard. In addition, OSHA is proposing to amend an appendix toclarify that PortaCount® fit test devices equipped with the N95-CompanionTM Technologyare covered by the approved PortaCount® protocols.
