Hotel / Restaurant, Restaurant Yuma, AZ – Fire at downtown eatery contained by sprinkler system February 11, 2015 viking210 For the second time in as many months a sprinkler system had mostly extinguished a fire in a commercial building — this one in historic downtown Yuma — by the time firefighters arrived on scene. Yuma Fire Department spokesman Mike Erfert said that just before 2 a.m. Monday, a water flow alarm was received, indicating the fire sprinkler system had activated at the Prison Hill Brewing Company, 278 S. Main St. Erfert explained that once firefighters made their way inside the building they found that the fire had been contained and mostly extinguished by an activated sprinkler head. Firefighters ensured the fire was completely out and assisted with cleanup. Damage from the fire was limited to a small area around a container of rags where the fire was believed to have originated.
