SHERMAN OAKS ( — Two Los Angeles City firefighters became trapped and injured while battling a three-story house fire in Sherman Oaks early Saturday.

A crew was called to 4008 Sumac Drive, off Beverly Glen Boulevard, shortly after midnight, according to Erik Scott of the L.A. Fire Department.

Narrow, winding roads made it difficult for firefighters to reach the home.

A crew immediately requested additional resources upon arrival.

Conditions quickly became unsafe and firefighters were ordered out of the structure.

Two firefighters found themselves trapped in a segment in the home but found their way to safety.

One of the firefighters was initially hospitalized in serious, but stable, condition and the other in fair condition. They were both released Saturday afternoon.

Approximately 100 firefighters spent more than an hour to put out the blaze.

All three floors of the home sustained extensive damage. Officials estimate the fire caused $180,000 in damages to the structure and an $80,000 loss to its contents.

Arson investigators are combing through debris to determine what sparked the fire.
