Massive fire tears through Orange County Fire Authority station in Buena Park

BUENA PARK, Calif. (KABC) -- Firefighters on Thursday morning battled a stubborn fire that erupted at an Orange County Fire Authority station in Buena Park.

The blaze began about 3:40 a.m. at Station 61 in the 8000 block of Western Avenue, according to the agency. News video showed firefighters dousing massive flames burning inside the structure.

No injuries were reported in the fire, which was apparently brought under control by 7:30 a.m. but was still smoldering.

Five personnel were inside the station and four others were out on a call when the blaze began, according to OCFA Capt. Larry Kurtz. It was unclear how many of those in the building were asleep when a loud noise came from the garage area.

Witnesses said they heard an explosion. The fire department said it was unknown if an explosion ignited the inferno.

Several vehicles that had been parked inside the building were destroyed, according to the fire authority. They included a 100-foot ladder truck, a battalion chief's SUV, an OCFA pickup truck and a swift-water rescue boat.

Part of the structure was deemed unstable following the incident, whose cause was under investigation.
