"Go! Go! Go! Go! Go!" the unnamed deputy yells at one point to drivers who are hesitating and moving slowly as they flee.
The video was released Friday by the Sonoma County Sheriff's Office of the community of Mark West, which is lit up orange with flame and so thick with smoke it's difficult to see.
The deputy, wheezing and coughing, runs to several doors shouting "sheriff's office!" for anyone who may be in earshot.
He then comes across another deputy with a woman in a wheelchair right next to a house that is burning and lifts her into an SUV to take her away.
Back in his car, he appears to drive straight through the flames at one point as he tries to help evacuees to safety.
