Other / Not Specified, Other Business Merrimack, NH – Fire at century-old mill building controlled by sprinkler system March 14, 2015 viking210 On Friday, March 13, 2015, at 4:52 p.m. the Merrimack Fire Department was dispatched to 33 Elm St. The crew found a fire in an area of the building being used as a furniture repair and refinishing shop. The building sprinkler was keeping the fire from spreading but suppression crews were needed to fully extinguish the blaze as the sprinklers were being blocked by furnishings. The building is an approximately 135,000 square foot three story mill building built in 1900. The building now houses multiple tenants including warehouse, retail store and light industrial uses. The fire was declared under control at 5:49 p.m. and an extensive overhaul and ventilation of the building was begun. Damage to the building was moderate, with fire damage to a wall and contents of the shop as well as water damage to several areas. Crews ensured that all fire was extinguished and debris cleared from the area, and an investigation into the cause of the fire was conducted by the Fire Marshal. The building was turned back over to the owner and all fire personnel cleared at 8:02 p.m. The fire cause was determined to be electrical, due to overloaded circuits and improper use of extension cords. Mutual aid was received from a Nashua Fire Department Engine and Ladder, who assisted at the fire scene and a Manchester Fire Department Engine who covered Station 1.
