On July 10, 1995, 30 CFR Part 11 certification procedures were replaced by 42 CFR Part 84 procedures. Under the 30 CFR Part 11 approval system, manufacturers were required to mark cartridges and filters with an abbreviated label that included a NIOSH/MSHA approval number (“TC number”). Under the 42 CFR Part 84 approval system, cartridges and filter are no longer marked with a “TC number.” Instead, they are marked with “NIOSH,” the manufacturer’s name and part number, and an abbreviation to indicate the cartridge (e.g., OV, CL) or filter (e.g., N95, P100) type.
All cartridges and filters are to be supplied with a matrix approval label, usually as an insert in the box. This label shows the NIOSH approved configurations and includes the “TC number,” component parts, and cautions and use limitations.
Nonpowered particulate respirators that were approved under 30 CFR Part 11 and use the “old” labeling can be manufactured and sold until July 10, 1998. Distributors will be able to sell them and end–users will be able to use them until their inventories are depleted.
