Lehi Fire Chief Ricky Evans said a 40-year-old decided the fire in his briquette barbecue Monday evening was not large enough, so he poured white gas, most commonly used in lanterns, directly onto the grill. White gas is most commonly used in lanterns.
The vapors from the gas caught on fire and shot up the stream of liquid gas, exploding and catching the man's arm, hands, face and torso on fire, Evans said.
The man was flown to the burn unit at University Hospital, where he was in critical condition with third-degree burns over 36 percent of his body, Evans said.
Evans said it is better to use light fluid instead of white gas, and that it is not recommended to use anything once the fire starts going.''
A 42-year-old Salt Lake City jeweler suffered second- and third-degree burns on 50 percent of his body Monday night in a fire at his store. He was in serious condition at University Hospital. His 11-year-old daughter had minor burns on her face and hands, said Scott Freitag of the city fire department.
The man told fire investigators that he was working with a torch in the rear of the store when an explosion occurred. He said his daughter was at the front of the store at the time.
Two Crossroads Plaza security guards saw him trying to crawl out from under a metal door at the front of the store and got him out. He had been able to get his daughter out, fire spokesman Dennis McKone said.
The fire was confined to the work area in the back of the store. Smoke, water and fire damage was estimated at $45,000 to $50,000.
