Six oilfield workers are being treated for burns suffered on their job site late Tuesday morning in Karnes County.
Karnes County Sheriff Dwayne Villanueva said four of those workers appeared to be the most severely hurt.
Villanueva said when the call first came in, he thought they had been burned in a fiery explosion, but it wasn’t that.
He said it was “an explosion of ... hot boiling water while they were checking the site,” Villanueva said.
He said three medical helicopters from San Antonio took them to San Antonio Military Medical Center with what appeared to be second- and third-degree burns.
The other two workers were transported by private vehicles, but Villanueva said it's unclear where they were taken.
Villanueva said the workers were checking a pressure gauge on a pipe when it blew, releasing the powerful blast of steam and hot water.
An investigation is likely to confirm exactly what happened.
Meanwhile, it appeared as work continued Tuesday afternoon. Several vehicles were seen entering and leaving the site.
Villanueva said it was the latest incident in Karnes County related to the Eagle Ford oil and gas boom.
“It’s something we see every day. Every other day, something happens. We’re seeing more and more accidents,” Villanueva said.
