A fire at a San Francisco recycling warehouse was extinguished after burning for more than nine hours overnight from Monday to Tuesday.
The two-alarm fire was reported by a building security guard at 8:33 p.m. Monday at the Recology recycling warehouse at 401 Tunnel Ave. It was put out around 6 a.m. Tuesday, acting fire Capt. Jeff Covitz said.
The fire started in one building and spread to another connected facility, he said.
“Because it’s a trash collection facility, there’s just a lot of fuel,” Covitz said.
The material that caught fire was construction and demolition debris dropped off by residents and small contractors. Items are inspected to make sure they do not include toxic materials, according to Recology.
The fire produced a thick white-gray smoke and a lot of steam from the sprinkler system, Recology officials said.
One firefighter suffered a minor injury tackling the blaze, Covitz said.
Covitz said the fire caused $75,000 in property damage and $2,000 of damage to items in the buildings.
The cause of the fire is under investigation.
