Natural gas is a very safe form of energy but must be handled with care and respect. The safe and efficient operation of the natural gas system is a public concern. Incidents are rare but may occur, including leaks, ruptures, and ignition. Potential hazards may include construction or excavation near the gas facilities, land movement due to earthquakes, flooding or landslides, and other events that may damage the gas facilities.
Indications of a gas leak or rupture include:
- The smell of unusual odor, like that of rotten eggs. Natural gas is colorless and odorless, but odorant has been added to help customers smell gas if a leak were to occur.
- An unusual hissing or roaring noise coming from the ground or an above-ground pipeline.
- Discolored vegetation surrounding a pipeline, or water or dirt/dust blowing into the air.
