In a liquid hydrocarbon storage facility, fire broke out on a floating roof tank (12-m high) containing 9,300 m³ of unleaded gasoline (filled to the ¾ level). Lightning was the cause of this accident. Since the tank had not been fitted with fire-fighting equipment, the safety team elected to fight the fire with a hand-held hose from the truss atop the tank shell: the fire engulfed approx. 20% of the total circumference yet could not be contained by fire-fighters at the site, who were forced to withdraw. The fire spread over the entire roof, which ultimately sank; the tank was destroyed and damage was estimated at USD 10 million.
