US experience with sprinklers / John R. Hall. — Quincy : NFPA, 2011

Sumario: Automatic sprinklers are highly 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. In 2009, 4.6% of occupied homes (including multi-unit) had sprinklers, up from 3.9% in 2007, and 18.5% of occupied homes built in the previous four years had sprinklers. When sprinklers are present in the fire area, they operate in 91% of all reported nonconfined structure fires large enough activate sprinklers, excluding buildings under construction. When they operate, they are effective 96% of the time, resulting in a combined performance of operating effectively in 87% of reported non-confined fires where sprinklers were present in the fire area and fire was large enough to activate sprinklers. In homes (including multi-unit), wet-pipe sprinklers operated effectively 92% of the time. When wet-pipe sprinklers are present in homes that are not under construction and excluding cases of failure or ineffectiveness because of a lack of sprinklers in the fire area, the fire death rate per 1,000 reported structure fires is lower by 83%, and the rate of property damage per reported home structure fire is lower by 71%. When sprinklers fail to operate, the reason most often given (65% of failures) is shutoff of the system before fire began
