ESFR heads require a minimum of how many PSI and what water flow rate?

The correct answer is based on the specifications for Early Suppression Fast Response (ESFR) sprinkler systems, which are designed to operate effectively in scenarios where rapid suppression of fires involving high-challenge commodities is necessary. ESFR systems require a minimum pressure of 50 psi to ensure adequate water distribution and effective performance when activated.

Furthermore, a flow rate of 100 gallons per minute (GPM) is the standard requirement for ESFR heads to provide sufficient water volume to suppress and contain the fire promptly. This combination of pressure and flow rate is crucial for ensuring that the sprinklers can deliver an adequate amount of water to extinguish or control a fire quickly, minimizing damage and improving safety.

Understanding these specifications is essential for compliance with fire codes and standards, as well as for ensuring the overall effectiveness of fire suppression systems in various environments.
