SANTA FE — A man who apparently was welding a cooking oil tank died Friday in an explosion outside an automotive repair shop.
The man, whose name was withheld until his family could be notified of his death, was apparently a customer of the business, authorities said. A business partner of the auto shop owners knew the victim, saying he had worked for him as a welder.
Authorities said the man was welding a sealed tank in a box truck outside Brake Stop, 12301 state Highway 6, shortly before noon.
Santa Fe Fire Chief C.T. Tommy Anderson said the tank was used to store cooking oil. Pressure from the heat likely caused the tank to rupture, and a small fire broke out. Firefighters quickly extinguished it.
Shorty and Carol Kershaw of Santa Fe said they were in the shop’s waiting room, which is enclosed by glass, while having their car inspected. They felt the concussion, which rattled the building.
“It knocked me out of my chair, and glass blew on me,” Carol Kershaw said. “Smoke filled the whole place, and they told us to leave. My husband was sitting right next to me. We were about 20 feet from the explosion.”
Shorty Kershaw said he had a headache from the shock and the hint of an acidic-type smell that enveloped the room.
Biodiesel Plans
Anderson said the shop is owned by the Cortez brothers, who were among a group of business partners who approached city officials earlier this year asking permission to build a biodiesel plant near city hall.
The group, which includes Cortez Brothers Enterprises and Jerry Fariza of Fuel and Lube Biodiesel in Richmond, plans to sell biodiesel from the automotive shop soon.
Anderson said he saw no indication that the group was producing biodiesel at the automotive shop. He said the explosion was not the result of anyone making the product.
“This accident involves the equipment but not the process, and I don’t see anything that the tank was connected to,” Anderson said.
Collecting Oil
The business uses the box truck, which was parked between the automotive store and a liquor store, to collect cooking oil. The oil is used in the production of biodiesel.
Heat from a welding torch apparently produced enough pressure in the sealed tank, which could have contained cooking oil, to cause the tank to rupture, Anderson said.
Police Chief Barry Cook said the death appears to have been an accident. “He forgot to vent the tank and paid the ultimate price for it,” Cook said.
Fariza, who arrived after the explosion, said the man was a Houston resident and had worked for him as a welder and performed other jobs.
It was unclear why the man picked up the torch and began welding, apparently without telling anyone.
“He was a good man,” Fariza said. “I understand he was getting his car worked on. He was just known to take care of things without asking.”
Officials with the Occupational Safety and Health Administration and the Galveston County Health District are investigating, Anderson said.
