Before working on any potentially hazardous pipeline, what procedure must be completed?

Completing the lock-out procedure before working on any potentially hazardous pipeline is critical for ensuring the safety of personnel and the integrity of the system. This procedure involves isolating the pipeline from its energy sources and ensuring that it cannot be inadvertently opened or activated while work is being performed. By locking out the system, workers mitigate the risk of accidental releases of hazardous substances or sudden pressure surges that could lead to accidents or injuries.

Lock-out/tag-out procedures are standard safety protocols in industrial and maintenance settings. They ensure that everyone involved is aware of the ongoing work and that specific energy sources remain inoperative. This step is essential for compliance with safety regulations and helps to protect workers from serious injuries associated with unintentional equipment operation.

While checking for leaks, performing a pressure test, and reviewing equipment manuals are important tasks that may be part of pipeline maintenance or safety protocols, they do not specifically address the immediate risks associated with working on a potentially hazardous pipeline. Lock-out procedures directly prevent hazardous situations, making them the foremost priority before any work begins.
