Final answer:
The correct answer is option 2, Inspecting for leaks, which is not generally part of a rough gas piping inspection. Rough inspections include checking pipe sizing, support/bracing, and testing gas pressure.
Step-by-step explanation:
The correct answer is option 2: Inspecting for leaks. During a rough gas piping inspection, it is customary to check for the correct pipe sizing to ensure the system will function properly under normal operating conditions. Additionally, verifying proper support and bracing is essential to maintain the integrity and safety of the gas piping system. A critical step in this process is also to test gas pressure to confirm that the system can handle the typical pressures of operation without failure.
However, inspecting for leaks is typically not part of a rough inspection but a final step after the gas system has been completely installed and is ready to be put into service. The rough inspection focuses on the system's physical attributes and installation compliance, whereas leak tests are performed to ensure the functionality and safety of the completed system.
