PREVENTING CO EXPOSURE
Open a forward hatch, porthole or window to help prevent the accumulation of CO in the cabin and enclosed exterior
areas. Creating air circulation allows air to travel through the yacht’s interior. Have a trained marine technician inspect
the exhaust systems when the yacht is in for service, or if the operator notices a change in the sound of an engine or the
generator.
TO PREVENT SERIOUS INJURY OR DEATH BY ASPHYXIATION:
• Keep the engine room hatch closed when operating the engines and generator.
• Never occupy aft lounging areas, including the boarding platform. Never swim near the engine or generator exhaust outlets
while the engines or generator are running.
• Minimize the time spent getting underway; CO production is greater when the engines are cold.
• Maintain the propulsion and generator engines to optimize efciency, which reduces CO emissions.
For more information on carbon monoxide and yachting, contact marine organizations that produce safety publications.

The following chart displays possible situations where CO can accumulate. Become familiar with the following examples
and the suggested precautions to help prevent CO poisoning.
Blockage of exhaust outlets
can cause carbon monoxide to
accumulate in the cabin and
cockpit area – even when the
hatches, windows, portholes, and
doors are closed.
WARNING
NEVER OPERATE THE GENERATOR
WHILE THE YACHT IS MOORED
AGAINST ANOTHER YACHT, DOCK,
OR WALL STRUCTURE THAT COULD
BLOCK THE EXHAUST OUTLET.
