OUPV & 100-Ton Master · Operations — Carbon Monoxide
A particular carbon-monoxide hazard on motor vessels is:
- ACO only forms above 100°F
- BThe 'station wagon effect' and exhaust accumulation around the swim platform/aft deck, which can poison occupants✓ Correct
- CCO is harmless outdoors
- DCO is lighter than air and always rises away
Explanation
Engine and generator exhaust contains carbon monoxide. It can accumulate at the aft deck/swim platform and be drawn into the cabin by the low-pressure 'station wagon effect' when underway. CO is odorless and deadly; detectors, ventilation, and keeping people away from exhaust outlets are the defenses.
