The industrial environment dictates the type of respirator and respirator cartridges needed to protect worker's lungs and/or face. An effective respirator has to fit comfortably with a secure seal and not allow the tiniest particles to enter the breathing area inside the respirators mask. Respirators, surgical masks, n-95 respirators, supplied-air respirators, PAPR, CBRN should keep breathing resistance to a minimum.
Respirators and their cartridges should be NIOSH-approved and should be specific to
the breathing danger. A change-out schedule of the respiratory
cartridges must be implemented by a qualified professional unless the
canister or respiratory cartridge has an end-of-life indicator. The
change-out schedule should take into consideration the work practices
and conditions. Disposable particulate respirators should also protect
against airborne particles and ensure a secure seal and comfortable fit.
