Authorities say three workers have been injured in a fiery explosion at a South Texas well site that destroyed an oil tank, reports the Associated Press. The fire about three miles south of Pearsall burned for several hours before being extinguished around 9 p.m. Thursday.
Pearsall Volunteer Fire Department Chief Placido Aguilar said Friday that authorities are trying to determine what started the fire on a fracking tank, as three workers were on top. He says the fire then spread to a 30-foot tall oil tank, leading to an explosion that blew off the lid. Aguilar says nobody was seriously hurt. He had no further details on conditions of the workers, who were transported to hospitals to be checked. Pearsall is 50 miles southwest of San Antonio.
