When responding to a leak from the Buckeye pipeline, what is the correct number of turns for the manual shutoff valve?

The procedure for shutting off a pipeline leak, particularly from infrastructures like the Buckeye pipeline, involves specific operational standards. In this case, the correct number of turns for the manual shutoff valve is 24 full turns clockwise. This standard is established to ensure that the valve is fully closed, preventing any further leakage of hazardous materials.

Turning the manual shutoff valve clockwise effectively tightens the valve, which is a critical safety measure in response to a leak. It is essential for personnel to follow these guidelines accurately and consistently to maintain a safe environment during emergency response situations. Understanding the precise action required—such as the correct number of turns—serves both to protect responders and to mitigate further environmental risks.
