Which component must be tested yearly according to the procedures?

• A. Gauges
• B. Check valves
• C. Pressure relief valves
• D. Shutoff valves

Answer: (C)

The important idea is that safety devices designed to prevent overpressure must be verified every year. Pressure relief valves are there to vent excess pressure from the storage system and prevent tank rupture. The yearly test confirms the valve opens at the correct set pressure, has adequate relief capacity, and reseats properly after venting. If this valve isn’t functioning, overpressure could develop and lead to a dangerous release or failure. Gauges, check valves, and shutoff valves are maintained as well, but the procedures specifically require annual testing of the pressure relief valve because its proper operation is critical to preventing overpressure events.
