True or False: An underground gas pipe may be covered as soon as the air test is completed.

An underground gas pipe must not be covered immediately after completing the air test because it requires an inspection to ensure that the test results meet the safety standards and that the installation is correct. It is essential to confirm that no leaks are present and that the system complies with applicable codes and regulations. The inspection is a crucial step in the process, as it ensures the integrity and safety of the gas piping before it is buried. Covering the pipe without this inspection could lead to undetected issues that may cause future problems or leaks, creating hazards for both property and safety. Thus, the requirement for inspection before covering the pipe makes the statement false.
