Canadian Entry To Practice (CETP) Practice Test

The requirement for a leak check when gas service is restored after an interruption is grounded in the safety practices outlined in specific codes that govern gas installations and safety protocols. NFPA 54, which addresses the National Fuel Gas Code, emphasizes the need for safe practices in the installation and maintenance of fuel gas systems, including checks for leaks to prevent hazards when restoring service. Similarly, NFPA 58, which manages the storage and handling of liquefied petroleum gases, also includes guidelines for ensuring safety during service restoration, particularly for preventing gas leaks. Both codes establish comprehensive measures for verifying the integrity of gas delivery systems, thereby ensuring that safety is prioritized across different types of gas services. This alignment affects practices in both natural gas and propane installations. The other options do not represent the same scope of mandates relevant to gas service interruptions. NFPA 56, for example, focuses on the aspects of fluid gas systems but does not specifically mandate leak checks upon service restoration, making the selected answer encompassing and appropriate.
