3M use limitations
may be used in contaminant concentrations up to 10 times the Permissible Exposure Limit (PEL) with approved 3M cartridges and filters, and up to 50 times the PEL with approved 3M supplied air systems (3M 6000 Series half facepiece user instructions use limitations)
Do not use with beards or other facial hair or other conditions that prevent a good seal between the face and the faceseal of the respirator. (3M 6000 Series half facepiece user instructions)
NOTE: Not NIOSH or Brazil Ministry of Labor approved for use against methylbromide, radioiodine, or ozone. (3M 6000 Series half facepiece user instructions Table 6)
