Service Life of Chemical Cartridges and Particulate Filters
Failure to properly dispose of spent cartridges or fi lters, or respirators contaminated by hazardous
materials can result in personal exposures as well as environmental harm. Handling, transportation and
disposal of spent cartridges, fi lters, or respirators must comply with all applicable federal, state, provincial
and local laws and regulations.
3M™ Chemical Cartridges 6000 Series must be used before the expiration date on cartridge packaging.
The useful service life of these cartridges will depend upon the activity of wearer (breathing rate), specifi c
type, volatility and concentration of contaminants and environmental conditions such as humidity, pressure,
and temperature. Cartridges must be replaced in accordance with an end of service life indicator (ESLI),
established change schedule, regulations or earlier if smell, taste or irritation from contaminants is detected.
Particulate fi lters must be replaced if they become damaged, soiled or if increased breathing resistance
occurs. N-series fi lters should not be used in environments containing oils. R-series fi lters may be limited
to 8 hours of continuous or intermittent use if oil aerosols are present. In environments containing only oil
aerosols, P-series fi lters should be replaced after 40 hours of use or 30 days, whichever is fi rst.
