WARNING Do not use the data presented in this study as the sole factor in determining the respirator cartridge change-out schedule. An appropriate change-out schedule must be developed by a knowledgeable professional. It should be based on additional factors including the actual workplace conditions, work practices and other conditions which may affect respiratory protection. Failure to determine an appropriate change-out schedule can cause overexposure and result in serious personal injury or death.
