Dangers of Carbon Monoxide for Boaters
Carbon monoxide (CO) is a serious danger to boaters because it is a colorless, odorless, and tasteless gas that can quickly build up in enclosed or poorly ventilated areas of a boat. Here are some key dangers of CO for boaters:
1. Poisoning and Fatality
Inhaling CO can cause poisoning, leading to symptoms such as dizziness, headaches, confusion, nausea, and, in severe cases, unconsciousness and death.
2. Confined Spaces Risk
CO can accumulate in enclosed cabins, engine compartments, and below-deck areas, posing a high risk of exposure to anyone inside.
3. Backdrafting & “Station Wagon Effect”
When a boat is idling or moving slowly, exhaust fumes can be sucked back into the boat due to air currents, increasing CO exposure.
4. Blocked or Poorly Maintained Exhaust Systems
A malfunctioning exhaust system can leak CO into the boat, increasing the risk of poisoning.
5. Multiple CO Sources
Engines, generators, heaters, and even nearby boats can all produce CO, making it difficult to detect without proper ventilation and monitoring.
6. “Teak Surfing” or Swimming Near Exhausts
People swimming or hanging onto the swim platform of a boat with an operating engine or generator can be exposed to lethal levels of CO.
Prevention Tips:
- Install CO detectors in enclosed areas.
- Ensure proper ventilation and keep exhaust systems maintained.
- Avoid idling in one place for too long.
- Never swim near an idling boat’s exhaust area.
- Be aware of the symptoms of CO poisoning and act quickly if they appear.
By taking these precautions, boaters can significantly reduce the risk of CO poisoning and stay safe on the water.
