Manufacturing, Manufacturing Plant Merrifield, MN – Sprinklers contain fire at metal stamping business to front entry March 25, 2015 viking210 Five fire departments quickly mobilized Tuesday night to tackle what could have been a commercial structure nightmare, but a sprinkler system did its work. Flames were visible out the front entrance of a two-story vestibule at Clow Stamping. The fire was reported at 9:04 p.m. Tuesday. Twyla Flaws, Clow Stamping personnel manager, said at least 70 employees were working in the plant at the time and evacuated without incident. The fire call came between shifts as another crew comes in for the 10 p.m. to 6 a.m. shift. Flaws said it’s not unusual for the 10 p.m. crew members to arrive early and she thought one of those early arrivals may have been the one to spot the fire.
