Shortly before noon on Tuesday, Burton firefighters were called to Coastal Auto Salvage on Laurel Bay Road when smoke was seen coming from a large metal fuel tank, according to a news release.
The underground fuel tank had been removed from the former Hess gas station on Boundary street to the salvage yard.
Firefighters put out the blaze by climbing on the tank and spraying 200 gallons of firefighting foam inside, they say.
Fire officials think the fire started when heat from workers cutting the tank free heated up the diesel fuel still left in the tank.
When that heated fuel was exposed to oxygen while being transported, it caught on fire.
Officials say all their fire vehicles carry foam specifically for these kinds of fuel fires and spills.
