Search for the word "extinguish." Here are a few quotes.

1. The next step in the process (outlined in Chapter 2) is to calculate the hydraulics of the system in order to properly size the piping so that it will carry the necessary volume of water to extinguish a fire typical of the hazard being protected.

2. However, in most classes of occupancy, and especially those of light and moderate hazard, dry pipe systems have shown generally good results and, when properly maintained, can be relied upon to satisfactorily extinguish or control fires” [4].

3. It must be realized that by completing our calculation successfully, we are simply proving that the system’s pipe sizing will be of sufficient diameter to deliver the required volume of water to the area of fire origin, at the minimum required pressure, in order to extinguish potential fires in their early stages.

4. Fire sprinklers have a proven track record of controlling and extinguishing fires, using a small fraction of the water needed to fight the same fire with hose lines.


Most of the time, when extinguishment occurs, there is no need for an investigator. The exception is when there is major water damage, but even in those cases, cause determination is often straightforward.
