What must be done to determine compliance with code requirements before operating newly installed gas piping?

To ensure compliance with code requirements before operating newly installed gas piping, it is essential to conduct both an inspection and a test. Inspection involves a visual examination of the installation to confirm that it adheres to relevant codes and standards, checking for proper materials, connections, support, and overall installation quality. Following the inspection, testing is crucial, particularly for leak detection and ensuring the integrity and safety of the gas piping system. This testing usually involves pressurizing the system and monitoring it for any drops in pressure that would indicate leaks.

By combining both inspection and testing, you create a comprehensive approach to safety, ensuring that all aspects of the installation meet stringent regulatory requirements. This dual process helps to identify not only physical installation issues but also functional reliability, which is critical for safe operation. Therefore, the correct response captures the necessity of performing both actions to ensure compliance and safety in handling gas piping systems.
