PROTECTION FROM CARBON MONOXIDE (CO)
Following these simple steps to help keep CO from poisoning you, your passengers and others nearby:
- Know where and how CO may accumulate in and around your boat. This is particularly important when starting or running engines in boathouses, or near a sea wall. Boats that are moored in close proximity are also potential problems as the fumes from your boat or another boat can affect air drafts on all boats. Back drafting sometimes called the station wagon effect occurs when the fumes curl up over the swim platform and transom and into the boat, especially when canvas or other coverings can trap the fumes. Even in open air, consider wind direction, the boat's speed and trim angles.
- Maintain fresh air circulation throughout the boat at all times. CO concentration is greater when the engine is cold. Ensure the boat is situated to take advantage of maximum dissipation of fumes.
- If your boat is equipped with a generator, know where the exhaust outlet(s) is located and keep everyone away from the area.
- Ensure that appliance, air conditioning, heater, generator, or other on-board function that emits fumes is routinely and regularly provided with maintenance as described by manufacturers. Failure to do so can result in the accumulation of CO fumes.
- Never sit, teak surf, or hang on the back deck or swim platform while the engine is running. Teak surfing is NEVER a safe activity.
- Never move into areas under swim platforms where exhaust out- lets are located unless the area has been properly ventilated.
- Operation of boats at mile-high (5,250 ft.) or higher altitudes may affect CO production. Check with an authorized MasterCraft dealer before operating at higher altitudes to determine whether the engine may require additional tuning to prevent excessive CO.
- Although CO can be present without the smell of exhaust fumes, if you smell exhaust fumes, CO is also present. Take immediate action to dissipate these fumes.
- Treat symptoms of seasickness as possible CO poisoning. Get the person(s) into fresh air immediately. Seek medical attention.
- Install and maintain CO alarms inside your boat. Do not ignore any alarm. Replace alarms as recommended by the manufacturer.
- Follow Coast Guard safety checklists.
- Get a Vessel Safety Check. They are free! Your local U.S. Coast Guard Auxiliary can provide details or check www.uscgaux.org online to locate assistance.
