UPDATE: Oil tank blast sends smoke plume over Bossier City

BOSSIER CITY, LA (KSLA) – An oil tank filling a tanker truck with crude oil exploded Tuesday afternoon, sending a black cloud of smoke into the air over Bossier City.

We now know the cause of the explosion. Fire officials say the explosion was likely caused when the tank's heating system ignited flammable gases inside the tank.

The explosion happened about 1:45 p.m. at Plains Marketing, located on Benton Road near I-220.

Authorities say the truck driver who was loading the oil from the tank into the tanker heard a hissing sound, and then the tank exploded. The driver managed to run from the scene and was not injured.

The tank was blown 40 yards away from its original location.

When the first emergency response crews got to the scene, they noticed a second nearby oil storage tank was signaling a high pressure warning. They were able to fix the problem before anything happened with the second tank.

Firefighters had the blaze under control quickly, according to Bossier City Spokesman Mark Natale. One firefighter did suffer a minor injury when he burned his hand.

Natale also said some of the crude oil did spill. A team from the Department of Environmental Quality will assess any damage from the spilled oil.

Authorities say nearby Willis-Knighton Hospital had to shut down their air conditioning units because of the smoke.
