Early Tuesday morning, E811 was dispatched to the 9300 block of Cherry Hill Rd for an automatic fire alarm. While en route, dispatch advised that residents were reporting smoke in the building and filled the box. E811 crew found smoke conditions on multiple floors and advanced a hose line to flow water down the trash chute, which was determined to be the source of the smoke. Crews found and extinguished fire in the basement-level trash room. E811 operated for approximately 2 hours and helped companies set up ventilation before returning to service.
