NIOSH Docket Number 168

Total Inward Leakage for Respirators Other Than Filtering Facepieces and Halfmasks

The National Institute for Occupational Safety and Health (NIOSH) is working to develop appropriate standards and test procedures for respiratory protective devices (RPD) used to protect workers in hazardous environments. NIOSH has initiated a program to update portions of Title 42 Code of Federal Regulations Part 84 (42 CFR Part 84) to promote improved performance and reliability in the area of Total Inward Leakage (for respirators other than filtering facepieces and half-masks).

The concept paper was presented at the September 17, 2009 public meeting. Comments on this concept paper were accepted through October 19, 2009. Interested persons or organizations were invited to participate in this process by submitting written views, arguments, recommendations, and scientific data. Comments were invited on any topic related to this concept paper.

Official comments provided to Docket Number 168 relating to the draft concept paper for Total Inward Leakage (for respirators other than filtering facepieces and half-masks) will be evaluated and considered in developing the next draft concept, throughout the informal rulemaking process.
