It is a two sided sword for sure.
Are spriklers systems need, of course they are. Will it save a life, yes.
Will it remove some GLOs from campus, possibly.
When we built our new house, I pushed for sprinkler systems to be put in place then. But, the Alum who was financing it decide no go. Meanwhile, there were many safety factors put into place, receesed basement windows with steps in them. Fire exit in basement, fire escape from the second floor, fire retardent in all rooms, hallways, and stairs along with many smoke detectors, safety lights and alarms.
Older houses, god what an expense for sure.
But the safest factor is using ones head when it comes to using possible fire starting items, candles, overloaded extension cords, old wireing, etc.
