If You Live or Work Near a Pipeline

How can you tell where a pipeline is located?

Since pipelines are buried underground, line markers are used to indicate their approximate location along the route. The markers can be found where a pipeline intersects a street, highway, railroad, and at other locations along the pipeline.

The markers display the material transported in the pipeline, the name of the pipeline operator, and a telephone number where the operator can be reached in the event of an emergency.

If you plan to dig, you are required to call 811, 48 hours prior to any excavation as defined by law. Pipeline representative will mark the location, route, and depth of the pipelines at no charge.

It is a federal crime to remove or deface a pipeline marker sign.

Pipeline marker signs are important to public safety. It is a federal crime for any person to willfully deface, damage, remove, or destroy any pipeline sign or Right-of-Way marker.

Are markers always placed on top of the pipeline?

Markers indicate the general location, not the exact position, of a pipeline. They do not tell the depth or number of pipelines in the vicinity.

How can you recognize a pipeline leak?

  • Sound—Listen for any unusual noise coming from the pipeline.
  • Sight—A spot of dead vegetation in an otherwise green location may indicate a slow leak.
  • Flames (if leak has ignited)—Caution; some products burn with an almost invisible, pale blue flame. If you suspect a fire, do not enter the area.

Note: Not all Air Products pipelines carry flammable products.

What should you do if you suspect a leak?

  • Your first concern should be for your personal safety and that of those around you.
  • Immediately leave the area of the leak.
  • Remain upwind of the area of the leak.
  • Avoid driving in the area near the leak.
  • Avoid direct contact with escaping gas or liquids.
  • Avoid creating sparks or other sources of heat that could cause the escaping products to ignite and burn. If you find yourself in an area where you suspect flammable vapors are present, do not light a match, start an engine, or even switch on an electric light.
  • Turn off any running machinery (engines).
  • Immediately call your local 911 emergency number or notify your local fire department, police department, or other public safety officials. Tell them the location and nature of the emergency.
  • Immediately notify the pipeline operator. Call collect. Give the location, a description of the leak, and your name. (Keep the pipeline telephone number with your other emergency numbers; i.e., fire, police, ambulance. The telephone number is on the pipeline marker sign.)
  • Do not attempt to extinguish a fire on the pipeline Right-of-Way.

Pipeline contents can vary greatly.

  • Air Products pipelines carry both flammable and nonflammable gases.
  • Many pipelines contain colorless and odorless products.
  • Some pipeline gases are lighter than air and will rise.
  • Other heavier-than-air gases will stay near the ground and collect in low spots.
  • Any pipeline leak can be potentially dangerous.

Is there a pipeline on your property?

As a property owner, you may not be aware that a pipeline runs through your property. You can be sure by checking your property drawing or title report for pipeline easements. Rights-of-Way agreements, or easements, are written agreements between pipeline companies and landowners which permit pipeline companies to operate and maintain the pipeline through the landowner's property.

Easements give the pipeline company the right to access the pipeline area or "Right-of-Way." The pipeline Right-of-Way must be clear of any buildings, structures, or other "encroachments" which could restrict access to the pipeline. Right-of-Way easements protect the public and the pipeline.

Always call 811 as before digging as required by law.

About our pipeline Rights-of-Way

Pipelines are constructed on land that the pipeline company either owns ("fee land") or on which it holds an easement. A Right-of-Way agreement is called an easement. Easements provide us with a permanent, limited interest in the land and enable us to operate, test, inspect, maintain, and protect our pipelines.

Please keep our Rights-of-Way clean

Since we must have ready access to our pipelines at all times, it is important that our Rights-of-Way be kept free from obstructions. Don't plant trees or install structures, patios, pools, wells, or septic systems on the pipeline easement.

Review your easement agreement for uses that are permitted on our Rights-of-Way.

Home and landowners are required by law to call 811 prior to any excavation near a pipeline easement. In addition, the pipeline owner can be called.
