What is the relief pressure set for a propane cylinder?

250 psig
300 psig
375 psig
400 psig

The correct answer is: 375 psig

The relief pressure set for a propane cylinder is typically around 375 psig. This pressure is established to ensure safety and prevent the cylinder from bursting due to overpressure. The relief valve is a crucial safety feature that allows gas to escape when the internal pressure rises beyond a safe limit, thus preventing possible hazards such as leaks or explosions. Propane, being a liquefied gas under pressure, requires careful management of pressure to maintain its stored state and ensure safe handling. Setting the relief pressure at 375 psig allows for a margin of safety since normal operating conditions should not approach this pressure threshold. Understanding the significance of the relief valve setting is essential for a gas fitter, as it relates directly to safety standards and regulations governing the storage and handling of propane tanks.
