  • Make sure you know of all exhaust outlet locations and confirm they are not obstructed
  • Confirm that water flows from the exhaust outlet when motors or generators are running
  • Educate all passengers about the symptoms of CO poisoning and where CO may accumulate
  • Test the operation of each CO detector for proper functioning by pressing the test button
  • Open hatches or canvas enclosures if CO accumulation is suspected
  • When rafted to another boat, ensure that both boats are able to ventilate their exhaust away from themselves and eachother
  • Avoid swim platforms, or swimming, around or near a boat when the engine is running
  • Periodically examine the exhaust fixtures on your boat to be certain of proper performance
  • Always maintain your boat’s engine and exhaust system to reduce the risk of CO buildup
