- Here are the 3 big Southern California fires we're watching closely
Two civilians and 10 firefighters have been injured in the Airport Fire in Orange County, which as of Wednesday afternoon had burned more than 22,000 acres and prompted the governor to declare a state of emergency.
The move by Gov. Gavin Newsom clears the way to approve state and federal funding to deal with the firefight and its aftermath. Newsom also declared a state of emergency in Los Angeles and San Bernardino counties because of the Bridge Fire.
One of the civilians sustained unspecified burns and the other had a "medical issue" according to Kevin Fetterman, a division chief at the Orange County Fire Authority. He did not provide details on the medical issue.
The firefighters' injuries were minor, Fetterman said.
The Airport Fire, which ignited Monday afternoon in Trabuco Canyon near the city of Rancho Santa Margarita, prompted evacuations but so far no structures have been reported destroyed. Some structures off Ortega Highway — known as Highway 74 — have been either damaged or destroyed but the scope of the damage is unclear, Fetterman said. He did not give an exact location.
One family was airlifted to safety from a nearby trail, authorities said.
The basics
- Acreage: 22,376 acres as Wednesday morning
- Containment: 0%
- Structures destroyed: An unknown number off Ortega Highway
- Deaths: None
- Injuries: 12 — three civilians and 10 firefighters
- Cause: Spark from heavy equipment
How the fire started
On Monday at about 1:30 p.m., an Orange County public works employee using heavy equipment to move boulders inadvertently started the Airport Fire in Trabuco Canyon, along Trabuco Creek Road, according to fire officials.
"After placing a load of boulders, the operators began seeing smoke coming from the area of the loaders basket," Orange County Fire Authority Deputy Chief TJ McGovern said during a news briefing Monday night. "The operator and the supervisor used multiple fire extinguishers and the loaders to attempt to extinguish the fire while 911 was being called."
Firefighters rushed to try to contain the fire, fueled by high temperatures and dry brush. Flames threatened homes and infrastructure a little more than an hour after it started.

On nearby Joplin Trail, sheriff's helicopters rescued a husband and wife who were hiking with their 3 year old, airlifting them to the nearby RC Airplane Airport. A Trabuco Canyon resident was rescued along with his cat, according to Capt. Steve Concialdi from the Orange County Fire Authority.
As of late Tuesday, no homes have been destroyed, and crews protected radio infrastructure using back burns.
"When it gets hot and dry and the fuel moisture is extremely low in the vegetation, these fires can happen. And unfortunately it did," said Concialdi. "They were trying to prevent other fires by putting those boulders so that people wouldn't go back in there with off road vehicles, motorcycles, so forth."
I don't have equipment at this site, but as @Poketrevor45 pointed out to me, the Santiago Pk transmitter site in Orange County just burned in the last couple of hours. Insane footage. #AirportFire pic.twitter.com/lLaZwuU0oY
