To meet the U.S. National Institute for Occupational Safety and Health (NIOSH) requirement for
minimum (4 CFM/115 lpm) and maximum (15 CFM/424 lpm) air flow, the air control valves approved
for use with the 3M 7500 Series Respirators must be operated within the correct supply pressure
ranges and hose lengths. Failure to do so may result in sickness or death.
OSHA standard 1910.134 requires that employers provide breathing air which shall “meet at least
the requirements of the specification for Grade D breathing air as described in Compressed Gas
Association Commodity specification G-7.1-1997.” This air must come from a suitable external
source (e.g., breathing air compressor or bottle with breathing quality air). Failure to do so may
result in sickness or death. The 7500 Series respirator itself DOES NOT provide Grade D
breathing air or air that meets CSA Standard CAN3-Z180.1-00.
