Total inward leakage requirements for half-mask air-purifying particulate respirators
NIOSH Docket Number 137
On October 30, 2009, the National Institute for Occupational Safety and Health (NIOSH) published a notice of proposed rulemaking to establish total inward leakage (TIL) requirements under 42 CFR Part 84 for half-mask air-purifying particulate respirators, including both elastomeric facepiece and filtering facepiece types (74 FR 56141). The proposed requirements would have specified TIL minimum performance requirements and testing standards to demonstrate that these respirators, when selected and used correctly, provide effective respiratory protection to intended users against toxic dusts, mists, fumes, fibers, and biological and infectious aerosols (e.g. influenza A(H5N1), severe acute respiratory syndrome (SARS) corona virus, and Mycobacterium tuberculosis).
On November 18, 2009, NIOSH announced a public meeting on the proposed rule to be held on December 3, 2009 (74 FR 59501). In response to requests for an extension to allow interested parties additional time for comments, the comment period was extended by 90 days to March 29, 2010.
On April 20, 2010, NIOSH announced that the comment period would be reopened and extended to to September 30, 2010 (75 FR 20546).
On May 27, 2010, NIOSH announced a second public meeting to be held on July 29, 2010 to allow participants to make presentations to NIOSH, share results of any new research on the topic of filtering facepiece or other half-mask respirator inward leakage measurements, and offer any additional comments on the anticipated economic impact of the proposed rule (75 FR 29699).
NIOSH suspended all activity on this rulemaking in 2012. The NIOSH National Personal Protective Technology Laboratory has been collaborating with ASTM since 2015 to prepare a consensus standard establishing a respirator fit capability test for half-mask air-purifying particulate respirators. The scope of this standard will be to define performance requirements that could be used as part of a conformity assessment program to ensure certified respirators/families of respirators are capable of fitting a specified percentage of their intended user population.
Information on the development of concepts that led to this Notice of Proposed Rulemaking can be found in NIOSH Docket number 036 .
