3.Replace cartridges in accordance with an established change schedule or earlier if smell, taste or irritation from contaminants is detected.

NIOSH Cautions and Limitations

The following restrictions may apply. See NIOSH approval label.

A– Not for use in atmospheres containing less than 19.5 percent oxygen. B– Not for use in atmospheres immediately dangerousto life or health.

C– Do not exceed maximum use concentrations established by regulatory standards.

D– Air-line respirators can be used only when the respirators are supplied with respirable air meeting the requirements of CGA G-7.1 Grade D or higher quality.

E– Use only the pressure ranges and hose lengths specified in the User’s Instructions.

F– Do not use powered air-purifying respirators if irflowa is less than four cfm (115 lpm) for tight fitting facepieces or six cfm (170 lpm) for hoods and/or helmets.

G– If airflow is cut off, switch to filter and/or cartridge or canister and immediately exit to clean air.

H– Follow established cartridge and canister changeschedules or observe ESLI to ensure that cartridges and canisters are replaced before breakthrough occurs.

I– Contains electrical parts which have not been evaluated as an ignition source in flammable or explosive atmospheres by MSHA/NIOSH.

J – Failure to properly use and maintain this productcould result in injury or death.

L– Follow the manufacturer’s User's Instructions forchanging cartridges, canisters and/or filters. M– All approved respirators shall be selected, fitted, used, and maintained in accordance with MSHA,

OSHA, and other applicable regulations.

N– Never substitute, modify, add, or omit parts. Use only exact replacement parts in the configuration as specified by the manufacturer.

O– Refer to User’s Instructions, and/or maintenanc manuals for information on use and maintenance of these respirators.

P– NIOSH does not evaluate respirators for use assurgical masks.

S– Special or critical User’s Instructions and/or use limitations apply. Refer to User’s Instructions before donning.

S-Special or Critical User’s Instructions

3M™ Mercury Vapor Cartridge (6009 and 60929) are eq uipped with passive 3MTM End of Service Life Indicators (ESLI). The color change indicator must be readily visible when wearing the respirator without manipulation. If you cannot readily see the ESLI, do not use. Mercury vapor cartridges must be discarded when the ESLI changes color; or within 30 days of opening packaging; or when the ESLI becomes dirty or damaged; or when odors of vapors or gases become noticeable, whichever

occurs first. Mercury vapor has no odor.

3M™ Nose Cup Assembly 7881S or 7981S must be used i n all 7000 Series Full Facepiece applications except for Face-Mounted Power Air-Purifying Systems.

U.S. OSHA Standard 29 CFR 1910.134 requires that employers provide breathing air for supplied air respirator systems which shall “meet at least the r equirements of the specification for Grade D breathing air as described in the Compressed Gas Association Commodity Specification ANSI/CGA G-7.1-1997.” Testing of output air from a compressor against this standard is required prior to using with a supplied air respirator. In Canada, breathing air systems must be supplied with air which meets at least the requirements in Table 1 of CSA Standard Z180.1-00. Failure to do so may result in sickness or death.
