Fire investigators were trying to figure out Saturday what caused a fire to burn a Sherman Oaks house and that left two firefighters wounded while trying to put it out.
The fire broke out in the 4000 block of Sumac Drive just after midnight Saturday, said Erik Scott, a Los Angeles Fire Department spokesman.
Firefighters were challenged in getting to the location as they had to make their way up a narrow, windy road to get to the three-story home, Scott said.
Once they arrived, they saw a house fully engulfed in flames.
It took almost 100 firefighters just over an hour to put out the fire, Scott said.
Both unidentified firefighters suffered burns and were taken to a hospital.
One of them was a fire captain. He was listed in serious but stable condition. The second firefighter was in fair but stable condition, Scott said.
