An explosion in a metal building that injured one in Mississippi could have been worse, had crews not contained the resulting blaze from spreading to a 55-gallon drum of acetone and contained the runoff.

According to the Biloxi Sun-Herald, the barrel of acetone and one-gallon and five-gallon containers of acetone, resin and gel coating were in the metal building that caught fire Monday.

Officials said a worker was taken to a hospital for treatment of second- and third-degree burns, while another worker was treated at the scene.

Acetone is a flammable liquid that also can cause respiratory problems in humans. Direct contact isn't recommended.

The prefabricated metal building explosion happened in a structure used as a trucking facility, and adjacent to a local dealership.

Investigators later Monday were waiting to speak with the injured man to help determine what caused the metal building fire.

Responders temporarily closed the I-10 exit to Canal Road, the service drive and nearby roads, and evacuated neighboring businesses after the incident was initially reported around 11:30 a.m.

The metal building, used to make and repair fiberglass fenders, is one of several steel buildings behind the dealership's offices.

While it wasn't clear what the two workers were doing when the explosion occurred, the Gulfport, Miss., Fire Department responded quickly with a total of 22 firefighters and 11 units.

"Our firefighters were able to saw a hole into the side of the metal building and inserted a hose to keep the drum of acetone from igniting," the Fire Chief said. "It could have been a lot worse."

"In the scheme of things, it was very small quantities, not like a big, above-ground storage tank," he added. "The fire department did a really good job of containing the runoff inside the building."
