Service life indicator cartridge
3M has launched a new line of organic vapour respirator cartridges with 3M Service Life Indicator technology, an end-of-service-life-indicator (ESLI) that, when used in appropriate environments, visually shows when users should change cartridges. The Service Life Indicator can be used to complement a company’s current respirator cartridge change schedule, and in some cases replace it. Workers simply peel back a removable sensor protector to view the indicator bar and, in appropriate environments, determine when to change the cartridge. The indicator can also help optimize cartridge change schedules across workers because it is designed to indicate service life based on individual exposure and breathing patterns. Using a respirator cartridge beyond its service life can endanger workers and lead to regulatory violations.
