Service Life of Chemical Cartridges and Filters
The useful service life of chemical cartridges will depend upon the activity of the wearer (breathing rate),
the specific type, volatility and concentration of the contaminants and environmental conditions such as
humidity and temperature. The integrity of the respirator should be checked and the cartridges replaced
according to the cartridge change schedule or as soon as the wearer begins to smell or taste the
contaminant(s) or irritation occurs.
Do not use when airborne concentrations of contaminants exceed the maximum use concentration (MUC)
of the respirator. See fit testing section of these User Instructions.
If respirator becomes damaged or breathing becomes difficult, leave the contaminated area immediately
and repair or replace the respirator. When used for non-particulates (eg. hazardous vapors or gases) a
change out schedule regarding the contaminants of interest, for the cartridge, must be established.
Dispose of cartridge after initial use in accordance with applicable regulations.
