The firefighters, 26 and 31, were injured while battling the Silverado Fire, which had charred at least 7,200 acres in and around the community of Irvine, southeast of Los Angeles, Orange County Fire Authority Chief Brian Fennessy said.
The firefighters---two of about 500 trying to contain the out-of-control blaze---suffered second- and third-degree burns across 65% and 50% of their bodies, the authority said. Both were intubated.
