What is the maximum pressure specification for supply hoses?

The maximum pressure specification for supply hoses is set to ensure safety and functionality under operational conditions. Supply hoses are designed to operate under certain pressures to prevent failure, which could lead to serious hazards during firefighting operations.

The correct value of 185 psi aligns with industry standards and testing protocols for fire service supply hoses, allowing them to effectively transport water from hydrants or other sources to the pump. This pressure specification accounts for the stresses that hoses endure in real-world scenarios, including temperature variations, wear and tear, and the dynamic pressures experienced when water is flowing.

In contrast, other options provided reflect lower pressure ratings that do not meet the current operational requirements for modern firefighting strategies, which necessitate robust performance capabilities. Understanding these specifications is crucial for firefighters to ensure they are using equipment that can handle the demands of emergency responses.
