2.5.4 Consider the carbon monoxide hazard
Carbon monoxide (CO) is an odorless but potentially lethal gas! Be aware of and avoid situations in which there is a risk of CO accumulation.
Carbon monoxide (CO) is harmful to your health in higher concentrations, and can even be lethal. Even low concentrations of CO can cause damage with prolonged exposure.
Prevent the accumulation of CO in the first place by minimizing the risk situations.
Act quickly if the CO alarm turns on or if you suspect CO poisoning.
Engine exhausts contain carbon monoxide (CO). High CO concentrations can occur especially when:
- Running the engine in confined spaces in a standstill, for example with the boat close to another vessel or with the engine next to a wall.
- Driving at slow speeds or in a tailwind.
- Driving with the bow high.
Running the engine with the cabin door open may cause exhaust fumes to enter the cabin.
To prevent CO accumulation:
Procedure
- Do not rev or idle the engine unnecessarily, for example when mooring or when there are persons in the water.
- Do not block exhaust outlets and inspect the exhaust system regularly.
- Ensure all areas on the boat are kept well ventilated if you’re using a diesel heater or any other fuel-burning device.
- Keep the cabin door closed when running the engine.
- Leave enough space between the engine and any obstacle.
