Nashua, NH – Factory fire held in check by sprinkler system; Firefighters extinguish blaze

Fire officials credited the sprinkler system in a large Crown Street factory with holding a smoky fire at bay until firefighters were able to get inside and attack the source of the flames late Saturday night. Capt. Karl Gerhard said crews responded shortly after 10 p.m. to Greenerd Press & Machine Co., 41 Crown St., after an activated sprinkler head triggered the building’s fire alarm system. At first, Gerhard said, firefighters found no indication of smoke or fire on three sides of the building. However, upon entering a secured fenced-off portion of the property and checking the fourth side, they cold see heavy smoke inside and water flowing from the sprinkler.

Crews forced their way in, and were met with “a heavy smoke condition” that caused “near-zero visibility,” Gerhard said. Due in large part to the size of the building, Gerhard said officials called for a working-fire response, which brought an additional engine and ladder truck to the scene. Meanwhile, firefighters, operating a hose line, made their way to the fire, which, Gerhard said, was being kept in check by water from the sprinkler.

Crews promptly extinguished the fire, which was declared under control 19 minutes after the first dispatch. Gerhard said crews spent an hour setting up large fans to remove smoke from the building. Nobody was inside at the time of the fire, and no injuries were reported. Gerhard said it appears the fire damage is minor, and that Greenerd employees will be able to conduct business as usual.

He said fire officials, after investigating the scene, ruled the fire accidental. Its likely cause, Gerhard said, was the improper disposal of rags containing chemicals used for staining, which resulted in spontaneous combustion. He pointed out the importance of reading and following manufacturers’ instructions regarding the proper disposal of cleaning rags, and cloths and rags used to apply finishing products.
