What must occur regarding the visual inspection of an EGT system in a vault?

  1. Inspections must be conducted daily

  2. Inspections must occur every time the system is operated

  3. Inspections are unnecessary if the system is not in operation

  4. Inspections can be conducted less frequently than monthly

The correct answer is: Inspections must occur every time the system is operated

When it comes to the visual inspection of an Electronic Leak Detection (EGT) system in a vault, it is mandated that these inspections occur every time the system is operated. This requirement is crucial because any operational changes in the EGT system could potentially lead to leaks or other issues that might compromise safety and environmental protection. By conducting these inspections at each use, inspectors can verify the integrity of the system, ensuring that all components are functioning correctly and any signs of wear or malfunction are promptly addressed. This practice emphasizes the importance of vigilance in maintaining the system's reliability while safeguarding public health and the environment. Regular inspections serve as a proactive measure to catch any potential problems before they escalate, which aligns with best practices in operational protocols for hazardous materials management.
