AIR PURIFYING RESPIRATORS Sample Clauses
The AIR PURIFYING RESPIRATORS clause establishes requirements for the use of respirators that filter contaminants from the air in environments where air quality may be compromised. It typically specifies the types of respirators that must be used, the conditions under which they are required, and the responsibilities of both employers and employees regarding their proper use and maintenance. This clause ensures that workers are protected from inhaling hazardous substances, thereby promoting workplace safety and compliance with occupational health regulations.
AIR PURIFYING RESPIRATORS. 3.4.1 Negative pressure - half or full-face mask: Supply a sufficient quantity of respirator filters approved for asbestos, so that workers can change filters during the workday. Require that respirators are wet-rinsed, and filters discarded, each time a worker leaves the Work Area. Require that new filters be installed each time a worker re-enters the Work Area. Store respirators and filters at the job site in the changing room and protect totally from exposure to asbestos prior to their use.
3.4.2 Powered air purifying - half or full-face mask: Supply a sufficient quantity of high efficiency respirator filters approved for asbestos so that workers can change filters at any time that flow through the face piece decreases to the level at which the manufacturer recommends filter replacement. Require that regardless of flow, filter cartridges be replaced after 40 hours of use. Require that HEPA elements in filter cartridges be protected from wetting during showering. Require entire exterior housing of respirator, including blower unit, filter cartridges, hoses, battery pack, face mask, belt, and cords, be washed each time a worker leaves the Work Area. Caution should be used to avoid shorting battery pack during washing. Provide an extra battery pack for each respirator so that one can be charging while one is in use. END OF SECTION - 01562
AIR PURIFYING RESPIRATORS. A. Negative pressure - half or full face mask: Supply a sufficient quantity of respirator filters approved for asbestos, so that workers can change filters during the work day.
B. Powered air purifying (PAPR) - half- or full-facepiece mask: Supply a sufficient quantity of high efficiency (HEPA) respirator filters approved for asbestos so that workers can change filters at any time that flow through the facepiece decreases to the level at which the manufacturer recommends filter replacement. Provide an appropriate flow verification device in the clean room of the Decontamination unit at all times. Require that the HEPA elements in filter cartridges be protected from wetting during showering. Require entire exterior housing of respirator including blower unit, filter cartridges, hoses, battery pack, face mask, belt, and cords to be decontaminated each time a worker leaves the Work Area.
AIR PURIFYING RESPIRATORS. A. Respirator Bodies: Provide half-face or full-face type respirators. Full-face respirators shall be equipped with a nose cup or other anti-fogging device.
B. Filter Cartridges: Provide, at a minimum, HEPA type filters labeled with NIOSH approval for "Radionuclides, Radon Daughters, Dust, Fumes, Mists including Asbestos-Containing Dusts and Mists" and color coded in accordance with ANSI Z88.2. In addition, a chemical cartridge section may be added, if required, for solvents, etc., in use. In this case, provide cartridges that have each section of the combination canister labeled with the appropriate color code and NIOSH approval.
