What is the maximum length of time a fire hose may be used in service without a service pressure test?

• A. Six months
• B. Twelve months
• C. Eighteen months
• D. Twenty-four months

Answer: (B)

Periodic service pressure testing is used to verify that a fire hose remains safe and capable after exposure to use, heat, abrasion, and chemicals. Because hoses can develop weak spots or leaks over time, they must be checked regularly rather than left in service indefinitely. The maximum time a hose can stay in service without a service pressure test is twelve months; annual testing helps catch hidden damage before it leads to a failure on scene. Failing to test for a full year increases the risk of sudden rupture under pressure, which is why once a year is the standard practice. Shorter intervals may be more protective but are not the typical requirement, and longer intervals risk undetected deterioration.
