This incident reminds us of the consequences of failing to recognize static electric ignition hazards of containers, piping, and any equipment used to handle flammable and combustible liquids or gases, combustible mists, or combustible dusts. A customer was filling an ungrounded gasoline can in the cargo area of a truck when the vapors were ignited by a static electric discharge. The fire caused severe damage to the truck and the gasoline station. The customer suffered severe burns on both legs, and it could have been much worse if four bystanders had not managed to extinguish the flames using their own clothing.
