The bomb squad was called to a fire that gutted a home in Yorba Linda on Wednesday after ammunition in the garage started exploding, authorities said.
Approximately 70 firefighters responded just before 1:40 p.m. to a house fire in 17200 block of Chestnut Street, Orange County Fire Authority Capt. Steve Concialdi said.
The two-story home was already fully engulfed in flames when firefighters got there, Concialdi said. Then fire crews reported hearing the sound of explosions.
"Ammunition was going off," Concialdi said. "It's not like a projectile, like shooting from a gun, but it's still loud and scary for everybody involved."
The bomb squad was called in to remove the ammunition and was determining the type of ammunition and how to safely dispose of it.
The primary home was a total loss, Concialdi said. The homeowner was treated for minor smoke inhalation but was OK and remained on scene. He had been trying to put of the flames with a garden hose.
The fire started in the backyard, fire officials said. But the cause was not known.
Fire got into the attic of a neighboring home as well, Concialdi said. Firefighters cut a hole in the roof of that home.
