Controlled Negative Pressure REDON Fit Testing Protocol

In this rulemaking, OSHA is approving an additional quantitative fit testing protocol, the controlled negative pressure (CNP) REDON fit testing protocol, for inclusion in Appendix A of its Respiratory Protection Standard. The protocol affects, in addition to general industry, OSHA respiratory protection standards for shipyard employment and construction. The Agency is adopting this protocol under the provisions contained in the Respiratory Protection Standard that allow individuals to submit evidence for including additional fit testing protocols in this standard. The CNP REDON protocol requires the performance of three different test exercises followed by two redonnings of the respirator, while the CNP protocol approved previously by OSHA specifies eight test exercises, including one redonning of the respirator. In addition to amending the Standard to include the CNP REDON protocol, this rulemaking makes several editorial and non-substantive technical revisions to the Standard associated with the CNP REDON protocol and the previously approved CNP protocol.
