What is the focus of NFPA 54 8.1.1.2 regarding inspection?

NFPA 54 8.1.1.2 emphasizes the importance of visual examination in the context of inspections related to gas piping systems. This focus on visual examination is critical for identifying any visible signs of issues such as corrosion, leaks, or physical damage to the system that might compromise safety. A thorough visual examination serves as an initial assessment, allowing inspectors to determine if more detailed inspections or tests are necessary. This foundational step is crucial in maintaining safety and ensuring that the gas piping system operates effectively without hazards that could lead to accidents or failures.

The other choices pertain to aspects of inspection that are either more specific or broader in scope than what NFPA 54 8.1.1.2 addresses. While some may involve pressure testing or contractor responsibilities, the key focus of this specific section within the NFPA guidelines is centered around visual examination as a primary means of ensuring safety in installations and maintenance.
