Fire sprinklers are highly reliable and effective elements of total system designs for fire protection in buildings. They save lives and property, producing large reductions in the number of deaths per thousand fires, in average direct property damage per fire, and especially in the likelihood of a fire with large loss of life or large property loss. Sprinklers are reliable and effective, according to a National Fire Protection Association Fire Analysis and Research Division report entitled "US Experience With Sprinklers, June 2013."
