PREVENTION CHECKLISTS
ALL CARBON MONOXIDE POISONINGS ARE PREVENTABLE!
Checklist for Each Trip
-
Educate all passengers about carbon monoxide poisoning.
-
Make sure all exhaust clamps are in place and secure.
-
Look for exhaust leaking from exhaust system components, indicated by rust and/or black streaking, water leaks, or corroded or cracked fittings.
-
Inspect rubber exhaust hoses for burned or cracked sections. All rubber hoses should be pliable and free of kinks.
-
Confirm that water flows from the exhaust outlet when the engine and generator are started.
-
Listen for any change in exhaust sound that could indicate an exhaust component failure.
-
Test the operation of each marine-rated carbon monoxide detector by pressing the test button. Make sure the battery is installed properly and is in good condition. Never remove the battery unless you are replacing it with a new battery.
-
Move seated passengers around the boat periodically to prevent anyone from continuously being near any fumes.
Checklist for At Least Annually
-
Replace exhaust hoses if you see any evidence of cracking, charring, or deterioration.
-
Inspect each water pump impeller and the water pump housing, and replace them if they are worn. Make sure cooling systems are in proper working condition to prevent overheating and possible burning of the exhaust system. (Refer to the engine and generator manuals for further information.)
-
Inspect each of the metallic exhaust components for cracking, rusting, leaking, or loosening. Pay particular attention to the cylinder head, exhaust manifold, water injection elbow, and threaded adapter nipple between the manifold and the elbow.
-
Clean, inspect and confirm proper operation of the generator cooling water anti-siphon valve (if equipped).
THE ANNUAL CHECKLIST TEST MUST BE PERFORMED BY A QUALIFIED MARINE TECHNICIAN.
