Total Inward Leakage Program for Respirators

The Program to add Total Inward Leakage requirements for all types of respirators as part of the NIOSH certification was begun in 2004. A public meeting to discuss the Concept, the half-mask air-purifying respirator benchmark testing results, and proposed requirements was held on June 26, 2007. The docket items related to that public meeting and the subsequent comments are listed below.
