What is the maximum operating pressure for extra hazard storage in a sprinkler system?

The maximum operating pressure for extra hazard storage in a sprinkler system is set at 175 psi. This standard ensures that the system can effectively deliver water to suppress fires in areas deemed as extra hazard, which require a higher level of fire protection due to the nature of the materials stored or the activities conducted there.

Extra hazard areas might include locations with flammable liquids, high-pile storage, or similar conditions that can significantly escalate the fire risk. A pressure of 175 psi is necessary to achieve the effective distribution and reach of water through the sprinkler heads in these scenarios. Higher pressures allow for greater distances to be covered and more robust performance overall, ensuring that the fire-fighting capability of the system meets the demands of these environments.

Understanding the specific requirements for extra hazard storage is critical for compliance with fire safety codes and the effectiveness of fire suppression systems.
