Carbon Monoxide Can Kill You
by Captain Alan Stopko

This is the time of year when we have the nicest boating. Few people on the lakes, beautiful fall leaf colors and cool, clear stars at night are just a few reasons. Many boaters – pontooners and cruisers alike -- out this time of year have their canvas up to protect them from the elements.

This is a time when we have to remember about the danger, the killing effects of carbon monoxide poisoning. It is not something that should be taken lightly. A friend of mine had a bad CO experience involving a boat-load of people. Back at the dock, the fire department arrived expecting a major emergency. On that occasion major problems were averted.

What is carbon monoxide (CO) poisoning?

CO is a colorless, odorless, tasteless potentially deadly gas. You cannot see it or smell it. When inhaled, CO reduces the oxygen in the blood, and basically asphyxiates blood cells. It is a byproduct of combustion: boat engines, car engines, generators, cooking ranges, and space and water heaters. Cold or poorly tuned engines produce more carbon monoxide than warm, properly tuned engines.

What causes CO leaks?

Corrosion or rusting coming from prolonged exposure to exhaust gases and moisture is a major cause. Vibration in the up and down motion of pistons, and general wear and tear on engines are also causes. In addition, lack of proper engine maintenance and regular inspections by experienced and trained engine and generator mechanics will create CO problems. The leading cause of carbon monoxide poisoning, however, is exhaust leaks.

What are the symptoms of CO poisoning?

CO symptoms are many times confused with flu symptoms. Some experience shortness of breath, mild nausea, mild headaches, dizziness, disorientation, and diminished coordination.

What to do when you think someone has suffered CO poisoning?

• Evacuate the victim from the area into clear air immediately.

• Ventilate the location. Open all doors and windows.

• Turn off all engines and combustions sources.

• Take those subjected to CO poisoning to the hospital emergency room. The effects are cumulative. A simple blood test will indicate if CO poisoning has occurred.

• Investigate what caused the problem and take corrective action.

How can I prevent or reduce the chance of CO poisoning?

The best precaution against CO poisoning is to keep air flowing through the vessel. Educate family and friends as to the symptoms or signs of CO poisoning and how to handle it. When in the water while a generator or engine is running nearby, assign an adult to watch anyone swimming or playing in the water. Keep forward facing hatches open, even in inclement weather, thus allowing fresh air to circulate. Install 1 or 2 carbon monoxide detectors.

I use a 120v household detector as well as a battery operated one. Place them where people sleep and exhausts are located. Also regularly check the detectors verifying that they are working correctly. Test the operation of each carbon monoxide detector regularly.

Make sure the battery is installed properly and is in good condition. Never remove the battery unless replacing it with a new battery. Make sure engine room bulkheads are sealed against leaks into accommodation areas. Also make sure you keep your engines and generators in good repair. Never teak surf from the swim platform.

Lastly, just because you have not experienced a problem with CO before don’t become complacement. Take no chances. If you experience any symptoms listed above get all people to fresh air and take corrective action. Visit www.carbon-monoxide-poisoning.com for more symptom and treatment information.
