What is not permitted between the pressure relief devices and containers?

• A. Pipes
• B. Shutoff valves
• C. Expansion tanks
• D. Hoses

Answer: (B)

The answer involves understanding the function of pressure relief devices and the safety regulations surrounding them. Pressure relief devices are essential for preventing excessive pressure buildup in storage containers or systems by automatically venting gas or fluid when needed. Having shutoff valves installed between pressure relief devices and the containers is not permitted because these valves can obstruct the flow and prevent the release of pressure. If a pressure relief device activates and there is a shutoff valve in place, it can lead to dangerous situations, including the risk of an explosion, because the pressure cannot escape as intended. In contrast, pipes, expansion tanks, and hoses may be utilized in conjunction with pressure relief devices, as long as they do not interfere with the operation of the relief mechanism. Pipes can conduct fluids or gases safely, expansion tanks accommodate fluctuations in pressure without restriction, and hoses can be flexible conduits under controlled circumstances. Therefore, the presence of these other components does not pose the same risks as a shutoff valve would.
