Firefighters were called to a Safeway store on the 1700 block of Forest Drive shortly after 5 p.m. Saturday, Cpt. Phil Morris said. Crews were responding to a “water flow alarm” at the grocery store, Morris said. But when firefighters arrived, they found the fire in the adjacent nail salon, Vy Nails. The fire, located in a storage room at the rear of the salon, set off a single sprinkler head, Morris said. That contained the fire, but fire crews had to use their hoses to extinguish it. No injuries were reported.
