Is there always someone present in your business/facility during working hours who knows how to turn off the sprinkler system should it suddenly open up?
Even just one sprinkler head will put out an enormous amount of water very quickly...and over a pretty good sized area. In a fire, that is exactly what you want.
Sometimes the sprinkler system can go off for other reasons, or a very minor fire. When they do, they need turned off quickly. 15 or 20 minutes to figure out where and how to turn them off will be a soaking disaster.
It is kind of easy to forget who knows, especially if there is some normal turn over in personnel.
Can even happen when the boss, or whoever, is out of the building briefly.
It kind of goes in there with knowing how to cut the water off to the whole place and cut the power off. It is a fine line to be sure the facility is safe from someone using these for harmful purposes and still be sure the utilities can be stopped quickly in an emergency.
It may come down to who also knows where the keys are if locking the utilities is deemed necessary.
Knowing where and how to turn off the water can be a big deal in even small offices/facilities if things go haywire suddenly.
