Relief devices shall be tested at least how often to determine that they function satisfactorily?

Relief devices shall be tested at least how often to determine that they function satisfactorily?

• A. Daily
• B. Weekly
• C. Monthly
• D. Annually

Answer: (A)

Relief devices are safety components that must open reliably at their set pressure to prevent overpressure and protect people, equipment, and the environment. To be confident they will work when needed, they need regular confirmation that they will function properly, move freely, and vent as intended. In a bulk oil storage facility, the consequences of a relief device sticking or failing to open can be severe, so the practice emphasizes frequent verification of operability. Testing daily provides the quickest detection of any sticking, obstruction, leakage at the seat, or drift in the opening pressure, so any fault can be addressed before it’s tested by actual overpressure. While longer intervals might reduce the burden of testing, they increase the risk that a fault goes undetected, compromising safety. Therefore, the daily functional check is considered the best answer in this context.
