A fire totally destroys an unsprinklered room during a live, side-by-side demonstration at NFPA headquarters in Quincy, MA, on November 3, 2011. In the room outfitted with a single sprinkler head, the sprinkler activated after 20 seconds and quickly brought down the flames. Learn more at http://www.firesprinklerinitiative.org
