Where should Pressure Relief Devices be located in relation to temperature exposure?

The correct choice emphasizes that Pressure Relief Devices (PRDs) should be located where they are representative of the temperature of the fuel supply container. This is crucial because the primary function of a PRD is to relieve pressure in the event of a temperature rise, which could lead to excess pressure buildup in the container.

When PRDs are situated in locations that accurately reflect the temperature of the fuel supply, they can operate effectively to prevent potential failures, such as ruptures or explosions due to overheating. If the PRD is located away from the fuel's actual temperature, it might not activate in time, leading to dangerous situations.

Placing PRDs in a temperature-controlled environment, while it might sound safe, does not necessarily represent the actual temperature condition the fuel is facing, which can lead to a misalignment between the PRD's operation and the real conditions within the fuel container. Additionally, locating them near exhaust systems could expose them to higher temperatures than intended, risking premature activation or failure to activate when necessary. Thus, ensuring that PRDs are representative of the fuel supply container temperature is paramount for system safety and integrity.
