Yes, fire sprinkler systems are hugely effective. In fact, they’re the most widely used fire prevention system today on account of just how effective they are.
The reason they’re so effective is because they can douse the fire at the place and time of breakout, before it has chance to escalate and grow to a dangerous size. It can do this on account of the automatic activation which is triggered when it reaches a certain temperature. Usually, one or two sprinklers is all it takes to control and douse a fire.
They also only use the minimum water needed to control the fire, which means there is less damage to the property in the process.
So to summarize, yes. There are lots of fire prevention systems that are effective, but fire sprinklers such as those provided by fire sprinkler companies like AMSCO
are the best there is.
