This procedure serves as a critical framework that outlines the necessary steps and standards to ensure that the system has been installed properly and is functioning safely. A documented procedure typically includes guidelines on how to carry out inspections, what tests need to be conducted, the criteria for compliance, and how to record results.

This structured approach is essential because it ensures consistency in testing and compliance with regulations, thus maintaining the integrity of the gas system. It also provides a reference for all personnel involved in the process, ensuring that everyone understands their roles and responsibilities during the inspection and testing phases. Having such documentation is important not only for compliance with safety standards but also for accountability and traceability in the work performed.
