Carbon monoxide intoxication may occur if you are working with:

• A. Type C respirators
• B. Open flame heating systems outside the work area
• C. A compressor in a parking lot
• D. Electric heaters in the area

Answer: (B)

Carbon monoxide exposure comes from burning fuels and builds up when ventilation is poor. An open flame heating system uses combustion to produce heat, so it can emit CO into the surrounding air, and if that space is not well ventilated or if the CO can drift into the work area, intoxication is a real risk. The other options aren’t sources of CO in typical use: Type C respirators are protective equipment and don’t create carbon monoxide; a compressor outdoors in a parking lot would only pose CO concerns if it’s gas-powered and the exhaust were confined, which is less likely outdoors; electric heaters don’t burn fuel, so they don’t produce CO.
