United States of America (USA/497: Respirators (HS 9020))
The Centers for Disease Control and Prevention ("CDC") proposes to establish total inward leakage (TIL) requirements for half-mask air-purifying particulate respirators approved by the National Institute for Occupational Safety and Health ("NIOSH") of CDC. The proposed new requirements specify TIL minimum performance requirements and testing to be conducted by NIOSH and respirator manufacturers to demonstrate that these respirators, when selected and used correctly, provide effective respiratory protection to intended users against toxic dusts, mists, fumes, fibres, and biological and infectious aerosols (e.g., influenza A (H5N1), severe acute respiratory syndrome (SARS) coronavirus, and Mycobacterium tuberculosis).
