What is the maximum pressure that should be used with 5" hose for F.D.C. connections?

• A. 150 psi
• B. 200 psi
• C. 250 psi
• D. 300 psi

Answer: (B)

The maximum pressure that should be used with 5" hose for fire department connections is 200 psi. This standard is crucial because it helps ensure the integrity and safety of the hose system during operation. Exceeding this pressure can lead to potential damage or failure of the hoses, couplings, and fittings, which may compromise firefighting efforts and put personnel at risk. In firefighting operations, particularly with large diameter hose, maintaining a pressure within the recommended limits minimizes the risk of hose bursts or leaks that could hinder water delivery. Fire departments often adopt this pressure limit based on extensive testing and operational experience, ensuring a balance between effective water supply and the physical limitations of hose materials. Understanding these limitations is essential for firefighters and driver engineers to maintain safety protocols and ensure efficient fire suppression operations.
