When engines are running carbon monoxide can gather causing a hazard to those onboard.
- Operators of vessels fitted with a rear vented exhaust system (common with inboard engines) should remind passengers and swimmers to avoid the rear deck and swim platform areas when engines are running.
- Swimmers should not approach the area until the engine or generator has stopped running for at least 15 minutes.
- Be aware that carbon monoxide can remain in or around your boat at dangerous levels, even if the engine is no longer running.
- Carbon monoxide can accumulate inside the cabin, cockpit and bridge due to blocked exhaust outlets, or the effects of back drafting when operating at both high and low speed.
Symptoms of carbon monoxide poisoning include irritated eyes, headaches, nausea and dizziness.
Following is a list of things to do if you suspect a person has been affected by carbon monoxide.
Remember to proceed with caution. The victim may be in an area that has high exposure to carbon monoxide, placing you and others in danger.
- evaluate the situation and ventilate the area if possible.
- evacuate the area and place the affected victim(s) in fresh air.
- observe the victim(s) and administer oxygen if possible.
- contact medical help. If the person is not breathing perform cardiopulmonary resuscitation (CPR) until help arrives.
- shut off the potential source of carbon monoxide if possible. Correct ventilation problems and/or repair exhaust problems as appropriate.
