A fiery explosion injured three workers at an oil and gas well site near Pearsall, Texas on January 19th, 2012. Preliminary information indicates that welders were working near a truck that was unloading saltwater that contained liquid hydrocarbons. Sparks from the welders caused the explosion when they ignited vapors that were created during the truck’s unloading process. Ignited oil from the damaged well spread and burned several nearby trailers. The fire burned for several hours before it was extinguished by the Pearsall Fire Department around 9pm on Thursday night. Further updates on the conditions of the injured workers have not been reported following their transportation to the hospital.
