OSHA's Standard for respiratory protection, 29CFR 1910.134, requires Employers to implement a change schedule for all vapor and gas cartridges when there isn't an end-of-service life indicator on the cartridge.  This schedule must be site specific and take into consideration work site humidity, worker breathing rate as well as contaminant concentrations.
