Pipelines are, statistically, the safest way to transport energy products like natural gas. However, as with any method of transportation, accidents can happen. In the event of a pipeline emergency, it’s important you know the warning signs and protect yourself.
When natural gas is transported through a transmission pipeline like Alliance, it is odorless. An odor similar to rotten eggs is added when the gas enters a distribution pipeline system to your home, allowing you to detect a leak. Signs of a natural gas leak include:
- An odor similar to rotten eggs, diesel, oil or propane
- A loud whistling or roaring sound
- A steam-like cloud
- Unexpected frost on the ground
- Bubbling in wet areas
- Dying vegetation along the right-of-way
Actions to Take in the Event of a Pipeline Leak
- Operate phones or electrical devices
- Start vehicles or machinery in the area
- Come into contact with leaking substances
- Extinguish/eliminate ignition sources, like cigarettes or machinery
- Alert others in the vicinity
- Leave the area immediately on foot, in an upwind direction
Remember: if it’s too hot or too loud, you’re too close. If you suspect a leak, immediately leave the area on foot. Call 911 and follow their instructions.
SIGNS OF A NATURAL GAS LEAK
Unusual hissing, whistling or roaring
Unlike the natural gas delivered to your home, odorant is not added to gas on the Alliance system. However, a leak on the Alliance system may have a natural petroleum smell.
Steam-like cloud, frost on the ground, dirt blowing from the ground
Bubbling in wet areas
Dead or discolored vegetation
