In the event of a pipeline release, what should pipeline operations personnel do first?

In the event of a pipeline release, the first action that pipeline operations personnel should take is to shut down the originating station. This action is critical because it immediately halts the flow of product through the pipeline, thereby mitigating further leaks and reducing the potential impact of the release on the environment and public safety. Stopping the flow is essential to control the situation and prevent escalation.

While notifying the public, contacting authorities, and ensuring evacuation of nearby personnel are all important steps that follow immediately after securing the release, the priority must be establishing control over the pipeline system itself. By addressing the source of the problem first, personnel can manage the emergency more effectively and reduce the risk of additional hazards.
