All fuel containers must be clearly marked. Red coloured bottles are commonly available, and adhesive flammable liquid labels can be obtained. There have been many instances of burn injuries caused by mistaking fuel bottles for water bottles. Make sure yours is labelled, specifying the type of fuel (do not just label it ‘fuel’, specify the type). Operating methylated spirit stoves on Shellite or kerosene, or kerosene stoves on Shellite can cause explosions and severe flare ups. Fuel bottles should be made from aluminium or tin plated steel. The washer or gasket in the filler cap should be neoprene, and not natural rubber as this perishes rapidly from contact with petroleum fuels.
