Eight firefighters were burned Friday night while battling the Lodge Complex Fire in Mendocino County.
Cal Fire said the firefighters' injuries are serious, but not life threatening.
A helicopter arrived at UC Davis Medical Center just after 10:15 p.m. carrying five of the eight injured firefighters. The five are inmate firefighters assigned to hand crews with Cal Fire. The three others are government firefighters assigned to engines.
Cal Fire cannot describe the extent of their injuries yet, nor explain how the injuries happened -- it is still under investigation.
But, the injuries underscore the danger of this fire season.
"It's proving that this year it's a very dangerous fire season. The drought conditions are very tough," Cal Fire spokesperson Lynne Tolmachoff said. "It's scary enough for our firefighters. We urge the public if a wildfire is coming your way, you need to get out."
The Lodge Fire has already consumed 5,400 acres and is currently only 30 percent contained.
