Home Fire Sprinklers – Good for Communities

Fire sprinklers have been saving lives and protecting property for more than 100 years. Home fire sprinklers and commercial sprinklers are similar because they both respond quickly to a fire. Yet the systems have significant differences, and water supply is chief among them.

Fire sprinklers offer the ultimate fire protection for homes, where people are at greatest risk of fire injury and death.

Sprinklers make up for human error. And they operate automatically, even if residents are asleep when a fire starts.

Sprinklers react while the fire is still small, controlling the flames and smoke with 90% less water than the fire service would use if sprinklers weren’t installed. They reduce fire damage by 97% and reduce greenhouse gas emissions by 98%. Sprinklers also reduce wastewater pollution. (FM Global)

Fire sprinkler systems improve community infrastructure and protect residents and firefighters for generations to come.

Nine out of every 10 structure fire deaths happen at home. Fire sprinkler systems provide fast and automatic protection that prevents injuries and saves the lives of residents as well as firefighters. Sprinklers also protect property.

  • Sprinklers are connected along a network of piping, typically hidden behind walls and ceilings.
  • Each sprinkler operates individually – they do not flow water all at once.
  • Sprinklers operate in response to the high heat of a fire, not to smoke or smoke alarm activation.

In the majority of home fires, only one sprinkler controls the blaze. In this video: Water purveyors and members of the fire service discuss their experience with home fire sprinkler systems:

  • Life safety and property protection
  • Water connections, supply and usage
  • Community improvements
  • Environmental benefits of fire sprinklers
