SWG / Safety


	Natural gas pipelines are one of the safest forms of energy transportation in the United States. At Southwest Gas our ongoing safety programs meet or exceeds all federal and state requirements for safe pipeline operation and maintenance. However, natural gas pipeline leaks can occur due to natural disasters, damage by digging, or corrosion. That's why it's important to learn how to spot and react to a pipeline leak.

A leak may be present if you:

SMELL -
An unusual odor, like that of rotten eggs. Because natural gas is lighter than air, colorless, and odorless, an odorant is added to help customers smell gas if a leak occurs.

HEAR -
An unusual noise coming from the ground or an above-ground pipeline. A hissing or roaring sound may indicate escaping natural gas.

SEE -
Discolored vegetation surrounding a pipeline, or water or dirt blowing into the air.

IF YOU SUSPECT A LEAK:

Leave the vicinity immediately.
Warn others.
Do not light a match, start or stop an engine, use a phone, switch on or off lights, or do anything that might create a spark.
From a safe place, call Southwest Gas immediately, day or night; or call 911.
