What is the maximum discharge pressure for LDH according to NFPA 1932?

The correct answer is based on the specifications outlined in NFPA 1932, which governs the performance of fire hose. LDH, or large diameter hose, is designed for the efficient flow of water and must adhere to safety and performance standards set by this regulation.

According to NFPA 1932, the maximum discharge pressure for LDH is established at 200 psi. This limit is put in place to ensure the durability and structural integrity of the hose during operation, preventing failures that could lead to dangerous situations for firefighters and equipment. Exceeding this pressure could compromise the hose's ability to withstand operational stress, increasing the risk of hose rupture or leaks which could lead to a loss of water supply during critical firefighting efforts.

The specified maximum discharge pressure reflects a balance between operational effectiveness and safety, ensuring that the hose can deliver the necessary water flows without compromising the safety of personnel. Following these parameters is essential for maintaining compliance with fire service standards and ensuring optimal performance during emergencies.
