What is the purpose of pressure relief valves in LP Gas storage?

The purpose of pressure relief valves in LP Gas storage is to prevent over-pressurization of the tank. When LP gas is stored, it exists under pressure, and there can be conditions, such as temperature increases or filling errors, that may cause the pressure inside the tank to rise to dangerous levels.

A pressure relief valve serves as a safety measure by automatically releasing gas if the pressure exceeds a certain predetermined level, thereby preventing potential ruptures or explosions. This is essential for ensuring the safe operation of storage tanks and protecting both the equipment and the environment.

The other options do not accurately describe the function of pressure relief valves. While efficiency is important, it is not the primary role of these valves. Similarly, they do not enhance the aesthetic appearance of the tank nor regulate its temperature, both of which fall outside the scope of the valve's function.
