What information do Permanent Marking Signs that indicate a nearby pipe typically include?

Permanent Marking Signs are critical for ensuring safety and communication regarding underground pipelines. The correct information they typically include is the type of line, which identifies what the pipeline carries (such as gas, oil, or water), the name of the operator responsible for the pipeline, and an emergency contact number. This content is essential because it provides immediate information to anyone who may need to respond to an emergency or carry out excavation work nearby. Knowing the operator allows for rapid contact in case of a leak or other issues, while the type of line informs personnel about the potential hazards involved.

Although other options might seem plausible, they do not encompass the correct combination of information typically required on Permanent Marking Signs used for safety and operational purposes.
