Petaluma firefighters responded to a water flow alarm at 1340 Industrial Avenue at 7:30 p.m. yesterday, and arrived to find the odor of smoke and water coming out from under the structure’s
exterior doors. Crews forced their way into several of the building’s units, discovering one to be completely full of smoke with around three inches of water covering the floor.
The sprinkler system had fully extinguished the fire, which appeared to have started in an office area, according to the fire department. The system had caused minor flooding in an adjoining unit.
Crews shut down the system, evacuated the smoke and began removing water to prevent further damage.
