Supply hoses must be tested to what minimum pressure?

Supply hoses are essential components within firefighting operations, tasked with the critical role of transporting water from a source to the firefighting apparatus. The testing of supply hoses is vital to ensure that they can withstand the pressures they will be subjected to in real-world scenarios.

The minimum pressure at which supply hoses must be tested is set to ensure safety and reliability. A pressure of 200 psi is mandated because it exceeds the typical working pressure of most fire suppression systems. This level of testing not only verifies that the hose can handle the stresses of high-pressure situations but also helps identify any weaknesses or defects in the hose. In practice, raising the testing pressure above the daily operational levels ensures that firefighters can rely on the equipment during critical situations.

Testing hoses at 200 psi is consistent with standards set by organizations such as the National Fire Protection Association (NFPA), which provides guidelines that help maintain safety and effectiveness in firefighting operations. By adhering to this minimum pressure, fire departments can ensure that their supply hoses will perform adequately under pressure, reducing the likelihood of equipment failure in emergencies.
