The Orange County Fire Authority (OCFA), supported by Los Angeles County Fire Department (LACoFD) and Cal Fire, deployed 28 units, including OCFA Copter 2 and Helitanker 47, to combat the fire.
Tonner Canyon, owned largely by the City of Industry, has a history of wildfires, including a 16-acre fire in 2019 and the 2008 Freeway Complex Fire, which spurred multi-agency drills like the SOLAR exercise.
