OSHA has issued a Notice of Proposed Rulemaking to add two (2) quantitative fit-testing protocols to the agency’s Respiratory Protection Standard. The protocols would apply to employers in the general, shipyard and construction industries. This proposed rulemaking would allow employers greater flexibility in choosing fit-testing methods for employees. The proposed rule would NOT require an employer to update or replace current fit-testing methods, as long as the fit-testing method(s) currently in use meet existing standards. The proposal also would not impose additional costs on any private- or public-sector entity.
