OAKLAND -- A three-alarm fire early Monday in East Oakland heavily damaged three structures, including a vacant carpet warehouse, left a firefighter injured and displaced four residents from a home, officials said.
Officials said the fire erupted about 4:50 a.m. in an empty camper shell next to the carpet warehouse at 10115 San Leandro St. in the Stonehurst area, not far from the San Leandro border.
The fire quickly spread to the warehouse, which contained some carpet as well as cabinets and other wood items, officials said. When firefighters arrived, large flames were coming from the warehouse, power lines were falling and a gas line had ruptured, making efforts even more hazardous and causing outages in the area, officials said.
Battalion Fire Chief Lisa Baker said the fire spread to an adjacent empty warehouse on Pippin Street and a house next to that warehouse, prompting four residents there to evacuate. The Red Cross was helping them.
More than 60 firefighters responded to the scene. One firefighter suffered minor injuries and was treated and released at a hospital, officials said.
The fire was contained more than two hours after it started and was announced under control about 8 a.m., Baker said. She said firefighters remained on the scene until early afternoon to make sure there were no flare-ups.
Baker said the cause remains under investigation. She estimated damage to the three structures to be at least $900,000.
There have been reports of squatters inside the carpet warehouse, and officials are trying to determine if they played a role in the fire.
The downed power lines left 5,701 PG&E customers in the area without power, officials said. More than half had power restored by 7:20 a.m. All but 29 customers had power restored shortly before 8 a.m., a PG&E spokeswoman said.
Several streets in the area were closed while firefighters were on scene.
Elevated BART tracks run adjacent to San Leandro Street, but there was no disruption in service.
