- Abstract
- This report addresses risk vs benefit issues associated with the installation of residential fire sprinkler systems. A primary objective of this assessment is to rate the risk of potble water contamination from a residential sprinkler system, and consequently to evaluate the need for installing backflow prevention devices. Statistics and assumptions outlined in this report show that the present risk from fire (death and/or injury) is 11.1 times higher than the present risk of waterborne disease (illness). This finding alone demonstrates a significant benefit from installing residential sprinkler systems.
