Safety: Carbon Monoxide Poisoning

Boaters Urged To Understand Hazard

Each year, boaters are injured or killed by carbon monoxide. Most occur on older boats and within the cabin or other enclosed areas. In recent years, federal investigations have focused on a series of accidents involving large houseboats inwhich the exhaust from gasoline generators has injured or killed individuals.

You probably know that carbon monoxide poisoning is a danger when gasoline-powered engines are run in enclosed spaces. What many people don’t know is that severe carbon monoxide poisoning can also occur outdoors and has been linked with houseboats.

The Problem

Since 1994, there have been at least nine carbon monoxide-related deaths on houseboats, and more than 100 non-fatal poisonings in the U.S. Studies indicate that houseboats with on-board electricity generators that vent toward the rear of the boat can pose a danger of carbon monoxide poisoning to people on the rear swim deck or water platform. Carbon monoxide poisonings have also occurred inside houseboats.

Gasoline-powered engines on houseboats, including the houseboat’s onboard generator, produce carbon monoxide, a colorless and odorless gas that can poison or kill someone who breathes in too much of it. Carbon monoxide tends to build up above the water near the water platform. The amount of carbon monoxide that can build up in the air space beneath the stern deck on houseboats can be deadly within seconds to minutes and can also reach life-threatening concentrations on and near the swim deck.

The Effects

The most common symptoms of carbon monoxide poisoning are headache, dizziness, weakness, nausea, vomiting, chest pain, and confusion. High levels of carbon monoxide can cause loss of consciousness and death, or can cause someone to pass out and fall into the water and drown. Unless suspected, carbon monoxide poisoning can be difficult to diagnose because the symptoms seem like other illnesses. People who are sleeping or intoxicated can die from carbon monoxide poisoning before ever experiencing symptoms.

If you think someone on your houseboat has carbon monoxide poisoning, move him or her to fresh air quickly and contact your nearest emergency services.

Prevention

How can you prevent carbon monoxide poisoning on or around your houseboat?

  • Install and maintain a working carbon monoxide detector inside the houseboat (remember, this won’t alert people to dangerous levels of carbon monoxide at locations outside the houseboat cabin, such as the swim deck).
  • Make sure that all fuel-burning engines and appliances are properly installed, maintained, and operated.
  • Educate all passengers about the signs, symptoms, and treatment of carbon monoxide poisoning, especially if the houseboat has a rear swim deck or water platform.
  • Watch children closely when they are playing on rear swim decks or water platforms for signs of carbon monoxide poisoning.
  • Swim and enjoy other activities away from areas where gasoline-powered engines vent their exhaust.
