Fire Hose Pressure Safety

Fire hoses are tested annually for the safety of hoses and their ability to withstand the pressure of water marked as their maximum load. Pressure tests are conducted using engine pumps or a testing machine.

Standard

• The safety of fire hoses under pressure is subject to the National Fire Protection Association's (NFPA's) Standard 1962 for the Care, Use and Service Testing of Fire Hose including Couplings &Nozzles. Hoses undergo a visual inspection before they are pressure-tested.

Pressure

• Hoses can be pressure tested to levels up to 10 percent over the highest pressure they would use during service. Hoses less than 5 inches in diameter are generally tested to around 300 pounds per square inch (psi), while those more than 5 inches in diameter are tested to 400 psi.

Leaks

• Where leaks are detected following fire hose pressure safety testing, a length of hose must be repaired before a second test is completed.
