To reduce carbon monoxide exposure on board, ensure proper ventilation around which equipment?

• A. Life jackets
• B. Engines and generators
• C. Fire extinguishers
• D. Steering wheel

Answer: (B)

carbon monoxide on board mainly comes from the exhaust of combustion engines and generators. Proper ventilation around those spaces prevents CO from building up in cabins or other enclosed areas, because it helps push the exhaust out overboard and brings in fresh air. When engines or portable generators are running, keep the ventilation system functioning and ensure exhaust outlets are clear and directed outside. The other items listed aren’t sources of exhaust, so they don’t affect CO levels, though they’re still important safety gear. For extra protection, consider having CO detectors in living areas.
