Today we were dispatched for a box alarm response for smoke inside the business, Royal Farms on DuPont Blvd. Arriving units found a moderate smoke condition inside and still filling up the store. Both ladder companies investigated the roof and mechanical units to find one malfunctioning. All power and gas was secured, smoke conditions dissipated and used PPV fans to clear out the business. Stations 75, 85, 93 GeorgetownEMS and SCEMS were on the box.
