Never fill the fuel tank of an internal combustion engine inside a building. Petrol fumes are explosive and narcotic. Do not fill the fuel tank of a petrol-engined appliance while the engine is hot. Never use petrol as a fire lighting or fire refreshing medium.
Petrol vapour can flash back and ignite containers and operatives.
Never put or keep petrol in unsuitable containers. Some plastic containers will dissolve when petrol is put in them. Always use secure metal or approved plastic containers which are properly marked. Be careful not to spill petrol onto clothing. Should clothing become contaminated be careful to keep away from any source of ignition and change clothes as soon as possible.
