Some 100 firefighters battled a stubborn four-alarm fire Sunday at a commercial building in Irvine.
They were dispatched at 5:50 a.m. to the 1800 block of Kettering Street, the Orange County Fire Authority reported.
No injuries were reported.
“We have gained the upper hand on the fire. There was a very high volume of fire,” OCFA Capt. Tony Bommarito told KTLA.
He said it would be hours before investigators would be able to enter the building to try and determine what caused the fire.
“We still have hot spots in there, we still have roof collapse, so that’s why we haven’t called knockdown yet,” Bommarito said, adding “We’re pretty confident we should have knockdown shortly.”
Bommarito said flights were not affected at nearby John Wayne Airport despite the heavy smoke.
A sign outside the building said “Working Wardrobes,” KTLA reported.
Alton Parkway, between Gillette and Armstrong avenues, was closed and motorists were advised to use alternate routes, the Irvine Police Department said.
