At what psi does a typical sprinkler head operate effectively for fire suppression?

A typical sprinkler head operates effectively for fire suppression at around 15 psi. This psi level is sufficient to ensure that the water is dispersed at an optimal rate and pressure, allowing for effective suppression of fire. At this pressure, the water can create a fine mist that cools the flames and reduces the heat, simultaneously covering a wide area to suppress fire effectively.

Higher pressures may not necessarily improve performance and could cause excessive misting or unintended water damage, while lower pressures may not provide enough force to reach the flames efficiently. Understanding the appropriate pressure for sprinkler systems is crucial for firefighters and those in charge of fire safety to ensure effective fire suppression while minimizing potential collateral damage.
