Know any danger signs on your boat

Any of the following could be signs that CO is filling your boat:

• Staining, sooty smears, or discolouration on surfaces around an appliance or its flue
• Appliances that are difficult to light or keep lit, burn weakly
• Burners with yellow or orange or 'floppy' flames that threaten to go out

• An unfamiliar, or burning smell when an LPG or oil appliance is on
• Smelling or seeing smoke escaping regularly into the cabin when running your wood-burner or coal stove

• Smelling engine exhaust fumes regularly inside the cockpit or cabin
