L.A. County firefighter killed in explosion in Antelope Valley

One Los Angeles County firefighter was killed and another injured Friday in an explosion that ripped through an Antelope Valley quarry as fire crews responded to a burning front loader, officials said.

Authorities identified the firefighter who died as Andrew Pontious, a nearly two-decade veteran of the fire service who was most recently assigned to a four-member fire engine at Station 93 in Palmdale.

“A wonderful man. He was married. He was a father. It’s just such, such a tragedy,� said county Fire Chief Anthony Marrone.

As of Friday evening, officials hadn’t released any details about what caused the explosion, which occurred in the early afternoon in the 6500 block of East Avenue T in the Palmdale area.

Speaking to reporters Friday evening, Marrone said the firefighters were battling flames that hadengulfed “a very, very large articulated front loader that was working in a quarry� when the blast occurred.

“And I don’t know what exploded,� Marrone said during a news conference at Antelope Valley Medical Center.

Los Angeles County Sheriff’s Department Cmdr. Mark Reyes said the agency’s homicide bureau andarson unit had started a death investigation, but it was too early to say what caused the explosion.

Hours after the blast, a KTLA-TV Channel 5 helicopter showed firefighters continuing to spray water on the front loader.
