How can a certified respirator be recognized?
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 40 CFR Part 84 approval system, cartridges and filters 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 were allowed to be manufactured and sold until July 10, 1998. Distributors were able to s

Another good source for learning more about managing indoor air quality is Midwest Planning Service documents that can be purchased at the MWPS website. Q: I have heard that agricultural operations do not need to comply with OSHA 29 CFR 1910.134. Is that correct? A: When federal OSHA proposed the standard for respiratory protection, they did not propose to cover agricultural workplaces. However, the safety principles imbedded within the OSHA standard should be viewed as a set of “best practices” to be followed by employers even if they are not directly covered by the standard. Your state may have regulatory requirements for agricultural operations that are simila
