Carrying portable petrol tanks and transferring petrol can be extremely hazardous if care isn't taken. Petrol and its vapour are highly flammable and can cause serious fires and explosions. Other fuels bring their own risks and should be handled with equal care. This Part complements Part Two (inboard engines) and reflects the additional risks of having portable fuel systems on boats.

By ensuring that fuel doesn't enter your boat, and that all components are suitable (see fixed fuel systems for outboard/power boats and portable fuel tanks & supply lines) for the fuel used, you can minimise the risks associated with escaped fuels. Making sure portable fuel tanks and spare fuel containers are made of a suitable material, are kept in good condition and are securely stored will also reduce the risk of fuel spillage.

The following Standards apply to all boats fitted with, orcarrying, outboard or portable engines, whether or not they are in use.

TAKE NOTE
It is essential, when handling fuel or filling your fuel tanks, that you make sure there are no naked flames around. If you have any appliances on board with a lit flame or automatic ignition systems, e.g. refrigerators, cookers, central heating boilers, etc. these must always be turned off before refuelling. Always fill portable fuel tanks on shore and well away from any sources of ignition.
