A brush fire broke out near the 241 Tollway in Irvine Monday, quickly spreading to 155 acres before its spread was halted.
No structures were threatened and only a single firefighter injury resulted from the blaze, which broke out just before 4:50 p.m. near the toll road and Santiago Canyon Road, Orange County Fire Authority Capt. Steve Concialdi.
The injured firefighter was taken to a hospital, Concialdi said.
About 300 firefighters were on the ground battling the fire at one point, aided by crews in eight helicopters and six air tankers, Concialdi said.
Firefighters were concerned the blaze would jump Santiago Canyon Road and worked to head it off before it reached the thoroughfare, OCFA Capt. Tony Bommarito said.
The blaze didn’t threaten the tollway, but northbound lanes were closed nonetheless, Bommarito said.
The fire’s spread was halted about 7:30 p.m., Bommarito said.
About 200 firefighters were expected to remain on scene building containment lines through the night and into Tuesday and helicopters would likely be redeployed after sunrise to hit hot spots within the burn area perimeter, Bommarito said.
Wind wasn’t much of a factor, but the fire was fueled by a great deal of dry brush, Concialdi said.
