CHAPTER 6
Carbon Monoxide Detector
If equippped, a carbon monoxide (CO) detector alerts you of
dangerous fumes.
Always avoid exposing your passengers or yourself to carbon
monoxide. Carbon monoxide gas is colorless, odorless and
extremely dangerous. All engines and fuel-burning appliances
produce CO as exhaust. Direct and prolonged exposure to CO
will cause death or brain damage.
Never tamper with the operation of the carbon monoxide
detector.
Never sleep while the engines or generator are running. People
sleeping onboard can easily be overcome by carbon monoxide.

Test the carbon monoxide detector
operation before each trip, at least
once a week and after the yacht has
been in storage. Also have the CO
detector professionally tested at
regular intervals. The detector is
required to be replaced every 5 years.
Refer to the equipment manufacturer's
manual for additional information.
