NIXON, Texas (AP) - Emergency officials say a fiery explosion at an energy company site in South Texas has left two workers with burns.
The Gonzales County Sheriff's Office says the explosion happened early Wednesday at a Vann Energy location near Nixon.
A sheriff's dispatcher says the workers were hurt during the fracturing process known as fracking. Chemically treated water is used to crack shale and release natural gas.
The dispatcher says both men suffered second-degree burns and have been airlifted to a San Antonio hospital. Their names and further details on their conditions weren't immediately available.
The cause of the accident has not been determined. Some nearby homes were evacuated for about two hours, as a precaution.
Company officials declined comment Wednesday.
Nixon is about 50 miles southeast of San Antonio.
