Firefighters on Tuesday morning finished battling a two-alarm blaze at a San Francisco public disposal and recycling center after nine hours of getting it under control.
No injuries were reported, but the smoke from the trash caused quite a challenge.
The fire was reported Monday at about 8:30 p.m. at the Recology dump station, 501 Tunnel Ave. where a large trash pile began burning inside a warehouse, causing smoke to pour out of a series of connected buildings.
The burning pile -- which officials describe as about 100 yards long and 8 feet deep -- is made up of mostly building material, such as old lumber and sheet rock. Officials said the blaze is expected to burn for quite some time due to the materials being very dense.
In addition, the heavy smoke is a challenge for fire crews, who took turns to battle the blaze.
Officials said the fire does not pose as a threat to nearby residents.
The San Francisco Fire Department responded to the blaze with 10 engines and three ladder trucks.
The cause of the fire is under investigation.
