1 person critically injured in 2-alarm fire

One person was critically injured in a two-alarm fire at a condominium in San Francisco’s Forest Knolls neighborhood Thursday morning, a fire department spokesman said.

The fire was reported at 8:05 a.m. at a three-story building at 622 Clarendon Ave. and firefighters were on scene two minutes later, fire spokesman Jonathan Baxter said.

Firefighters rescued an adult victim from inside the condo. The person was transported to Saint Francis Memorial Hospital’s burn center in critical condition, Baxter said.

The rescue was dangerous fore fire crews, with one firefighter having his entire leg go through a floor in the condo. He was able to get his leg free and was not injured, according to Baxter.

The blaze was declared under control at 8:37 a.m. after spreading to two adjacent units, causing minor damage, Baxter said.

He said investigators have not yet determined how many people lived inside the building where the fire started and the cause is under investigation.
