When a power outage occurs, the appropriate pipeline personnel should contact _______.

When a power outage occurs, it is essential for pipeline personnel to contact the power company. This is because the power company has the responsibility for the electrical infrastructure and can provide the most accurate information regarding the outage, including its cause, estimated time for restoration, and any necessary safety measures that may need to be taken while the power is out. Additionally, the power company can dispatch repair crews to restore electricity, which is crucial for the safe and effective operation of pipeline systems that may rely on electric power for their monitoring and control systems.

While contacting other entities might have relevance in specific circumstances, such as the one call notification system for digging activities or local authorities for public safety, in the immediate context of a power outage affecting pipeline operations, the most direct and useful action is to reach out to the power company. They are equipped to handle the situation effectively and can coordinate any necessary actions related to the power outage.
