Pipeline Awareness for Emergency Responders and Community Officials (RP 1162) Pipeline Markers—All along the rights-of-way there


are signs and markers to identify the approximate loca- tion of underground pipelines. Markers are required wherever a pipeline crosses under roads, railroads, or waterways. They may also be found at intervals along the pipeline right-of-way, and near buildings and above- ground pipeline facilities. Markers are normally placed within sight of each other. They may look different, but every sign should tell you the same information:


• Pipeline product • Pipeline operator


• 24-hour emergency phone number which responders can call for immediate help


• The word “danger,” “caution,” or “warning.”


WARNING—Markers do NOT tell you the exact location, depth or direction of the pipeline which may curve or angle around natural and manmade fea- tures. If there are multiple pipelines in the right-of-way, a marker sign should be posted for each one.

Pipeline operators use a combination of advanced technology and manage- ment processes to identify and mitigate risks that may damage a pipeline. Pipeline operators address each of the risks in different ways, following industry best practices and regulatory requirements. Most damage to under- ground pipelines is caused by excavators who either fail to call or fail to respect the marks even after calling.
