CARBON MONOXIDE IN THE WORKPLACE 19 365-BSA-01-IMOT © 2024, Workplace Safety & Prevention Services (WSPS) 1 877 494 WSPS (9777) | 905 614 1400 | WSPS.CA Controlling process emissions depends on maintaining performance standards. The most efficient means to achieve this is a program of regularly scheduled maintenance that includes documented procedures and performance records. This permits prompt diagnosis of problems prior to breakdown of equipment. The ventilation system plays an essential role in controlling exposure to carbon monoxide. For this reason, repairs to this equipment should be carried out when carbon monoxide is not being used or generated (i.e., during off-shifts and weekends, if possible). Exposure of maintenance workers must be considered. Exposure may arise from solvent or gases trapped in equipment under repair, or from emissions produced by equipment operating nearby. Written procedures that identify the appropriate protective equipment are necessary. Controls at the Worker Respiratory protection Carbon monoxide provides no warning of its presence or concentration. This limits the selection of respiratory protection. For example, the use of a chemical cartridge respirator is NOT recommended because there is no way of knowing when the cartridge is saturated. Canister-type respirators (gas masks) are permitted in some areas but are NOT recommended for the same reason. Those which are recommended are supplied air respirators, including: self contained breathing apparatus airline respirators Figure 4: Self Contained Breathing Apparatus Figure 5: An Airline Respirator WSPS.CA
