| Learn to Recognize Gas Pipeline Markers |
|
| Natural gas pipeline markers are usually bright yellow and display our name and 24-hour emergency phone number. If you see one, you’ll know a high-pressure natural gas pipeline is nearby and extra precautions are necessary. |

| Where You’ll Find Them |
| Natural gas pipeline markers are placed near our pipelines but not necessarily directly on top of them. These markers are usually found where a pipeline intersects a street, highway, railway or waterway and at other prominent points along the pipeline route. |
| For security purposes, pipeline markers do not show the exact location, path, depth or number of gas pipelines in the area. In addition, pipelines may not follow a straight course between markers. So while these markers can help you identify the general location of our gas pipelines, you cannot use them to determine a pipeline’s precise location. |
| A more reliable way to locate gas pipelines in your response area is to register with the National Pipeline Mapping System (NPMS). State and local government officials (including first responders) may apply there for access to the specific locations of transmission pipelines via the Pipeline Information Management Mapping Application (PIMMA). |
| Pipeline Markers Call for Extra Care |
| Pipelines can be damaged during accidents, emergency response and/or cleanup activities in an accident’s aftermath. Damage to a high-pressure natural gas pipeline can cause a gas leak that results in a catastrophic fire or explosion. |
| • |
Once a high-pressure natural gas pipeline’s location is established, take care to park emergency vehicles where their weight will not damage the pipeline. |
|
| • |
Additionally, be sure emergency cleanup and excavation equipment, such as backhoes, are operated a safe distance from the pipeline. |
|
|
| To help reduce the risk of excavation-related damage, a NIPSCO representative must be on-site to supervise any excavation near a high-pressure natural gas transmission pipeline. If you see excavation occurring near a pipeline marker with no utility personnel present, call the number listed on the marker. |
