Reliability of automatic sprinkler systems - An analysis of available statistics

Abstract: In this report statistics concerning the reliability of sprinkler systems from seven countries has been analysed. The objective of this report has been to determine the reliability of sprinkler systems in Sweden and to present suggestions on measures to increase the reliability. The main conclusion that has been drawn is that the reliability of sprinkler systems in Sweden is 92 percent according to the analysis of Swedish statistics, and that this figure finds support in statistics from other countries. Further results are that the quality of design, installation, maintenance and inspection of sprinkler systems has to be improved and that the Swedish incident report has to be revised.
