What is the primary function of a sprinkler system in fire safety?

The primary function of a sprinkler system in fire safety is to automatically extinguish fires. Sprinkler systems are designed to detect heat from a fire, and upon activation, they release water to suppress flames, directly addressing the fire at its source. This responsive action can significantly reduce the intensity of a fire and potentially prevent it from spreading, thereby protecting lives and minimizing property damage. While sprinklers may also help cool adjacent areas during a fire event, their main purpose remains the immediate suppression of the fire itself.
