Important safety information for gas customers
UES is committed to the safe operation of the pipelines used to deliver natural gas to our customers. By raising public awareness of the potential safety hazards associated with these facilities, we hope to reduce the likelihood and potential impact of pipeline emergencies and accidental releases of natural gas.
This site offers safety information for public officials, emergency workers, excavators and contractors, as well as, members of the general public.
The leading cause of damage to buried pipelines is the failure to identify the location of these facilities before excavation begins. Any contact with a natural gas pipeline that causes a scratch, gouge, crease or dent can lead to a leak.
Excavation activities can be as simple as planting a tree, installing landscaping, building a fence or digging for a swimming pool. So please be safe and call 811 or 1-800-STAKE-IT before breaking ground on any such project on your property.
Aside from accidental contacts, it is extremely unlikely that a natural gas pipeline will leak. Nonetheless, you should be prepared to recognize the signs of a leak and react appropriately if one should occur. Since natural gas is lighter than air, any underground leak can pose a danger at ground level.
Using your senses of sight, smell and sound will help you recognize a leak.
Sight – A dense fog, mist, or white cloud. Also, look for discolored vegetation, bubbling water or dust that is being blown away from a spot on the ground.
Smell – A distinctive odor is added to natural gas to help identify leaks.
Sound – A hissing, whistling or roaring noise can identify a potential leak.
Be careful not to touch, breathe or make contact with leaking gas. Do not light a match, turn light switches on or off, use a telephone or do anything that creates a spark near a potential gas leak. Also, do not attempt to operate any valves yourself – leave that work to a trained UES technician.
UES is dedicated to providing reliable service to our customers and to maintaining the safety of our employees and our equipment.
Before the first boom is lifted or the first spade of dirt is moved, it is imperative to consider if any electrical safety precautions are needed. Call UES before any construction, excavation, demolition or other work is performed at a work site that may involve UES facilities or equipment.
UES field employees will meet at no cost with property owners, builders or contractors at a work site to discuss safety concerns related to UES equipment. UES can implement preventative measures that can help protect against injury and preserve the integrity of UES electrical equipment that serves our community.
When UES determines it necessary, UES can de-energize or reconfigure UES electrical equipment at or near a work site. Calling UES before you begin any construction can help prevent unintended outages, injury, property damage and potential liability.
Natural gas satisfies the public's demand for a safe, reliable energy source. According to the U.S. Department of Transportation, the natural gas transmission and distribution network is the nation's safest energy delivery system.
The natural gas delivery system is operated under strict federal and state safety codes. UES and other utilities continuously monitor and patrol gas pipelines and follow strict pipeline safety procedures. Please call UES at 1-877-UES4YOU (1-877-837-4968) if you see anything out of the ordinary regarding our facilities.
Most natural gas pipelines are located underground, with line markers intermittently placed on the surface to indicate their approximate location. These markers do not indicate how deeply the pipeline is buried. Also, pipelines often take twists and turns between markers, so it's not safe to assume they proceed from marker to marker in a straight line. It is a crime for any person to deliberately damage, destroy or remove any pipeline marker or sign.
Any contact with a pipeline or its coating may cause future safety problems to the line and surrounding area. It is imperative that UES personnel inspect and repair any damage to our pipelines, no matter how minor it may seem. If digging or other activity damages or breaks a gas line, please call us at 1-877-UES4YOU (1-877-837-4968) immediately to report the incident. Call 911 if there is an immediate threat of fire or injury.
UES is ready to help you protect the public during a pipeline emergency. The following steps can help you ensure public safety until a UES representative is available for consultation on a specific incident.
UES shares emergency contact information with state and local agencies including fire departments, police and other first responders. We provide safety training to first responders and work closely with them to prevent and prepare for potential emergencies. Also, our Emergency Plans and Operations Procedures are on file with the Arizona Corporation Commission (ACC).
UES is committed to safe operations in all of the communities we serve. We're working closely with state and local leaders across Arizona to promote awareness of natural gas safety.
We want to be sure local leaders have access to all the information they need to:
Whatever your role in local government, you can have an impact on pipeline awareness and safety. For more information, please call us at 1-877-UES4YOU (1-877-837-4968) and we'll provide you with all the information you need to help keep your community safe.
Don't break ground on a project of any size until you see the distinctive lines marking the location of underground facilities at your job site. Beginning any excavation without first identifying the location of underground facilities can create a deadly safety hazard, not to mention significant liability for you and your company.
To protect the safety of yourself and others, call 811 or Arizona Blue Stake at 1-800-STAKE-IT (1-800-782-5348) at least two working days before you dig so that all underground facilities can be marked. UES and other utilities will mark the locations of their underground facilities at no charge to you or your company. It's not just a good idea – it's the law.
If you see that a pipeline is exposed, shallow or damaged, contact UES around the clock at 1-877-UES-4YOU (1-877-837-4968).
Any contact with a pipeline or its coating may cause future safety problems to the line and surrounding area. It is imperative that UES personnel inspect and repair any damage to a natural gas pipeline, no matter how minor it may seem. If digging or other activity damages or breaks a gas line, call UES to report the incident immediately. Call 911 if there is an immediate threat of fire or injury.
Written right-of-way agreements or easements between landowners and UES allow the construction and maintenance of natural gas pipelines across privately owned property. These pipeline rights-of-way or easements must be kept free from obstructions. To find out whether a UES pipeline is on or near your property:
