A Continental Carbonic tanker out of Decatur, Ill., hauling carbon dioxide caught fire Monday morning at the eastbound rest area on Interstate 40.
The Sallisaw Fire Department responded to the fire at 8:16 a.m. and used foam to extinguish the blaze. Firefighters continued to spray the tanker with water for about 20 minutes to cool it down, Sallisaw Fire Chief Anthony Armstrong said.
The cause of the fire was the brakes on the tanker locked up and caught the back tires on fire, Armstrong said.
The pressurized tanker consisted of two layers. The fire burned through the outside layer, but none of the gas was released, Armstrong said.
The Oklahoma Highway Patrol closed both eastbound lanes from 8:20 to 8:35 a.m. while firefighters put out the fire.
