What information is typically NOT indicated by Permanent Marking Signs?

Permanent Marking Signs are essential in providing critical information about underground pipelines to ensure safety and awareness among various stakeholders, including construction workers and emergency responders. These signs are designed to communicate important details regarding the pipeline's characteristics and the operator responsible for it.

The depth of the pipe is generally not indicated on Permanent Marking Signs because this information is subject to change due to factors such as soil erosion, construction, or other environmental influences. Instead, the signs primarily focus on conveying more stable and critical data, such as the type of line (whether it is carrying gas, water, etc.), the emergency contact number for immediate assistance, and the name of the operator responsible for the pipeline. This ensures that in the event of an incident, responders can quickly identify the nature of the pipeline and reach out to the appropriate personnel for guidance or information about the pipeline's contents and risks associated with it.

By omitting the depth from these markers, it helps reduce potential confusion and maintains clarity on the more relevant information needed for safety during excavation or emergency situations.
