Gas Information for YOUR Safety
Learn to recognize a natural gas leak
It is important for you to know how to recognize potentially dangerous natural gas leaks, so use your senses:
- Smell: Because natural gas has no odor in its natural state, we add a harmless odorant to it to help you detect a leak. The added odorant, called mercaptan, has a sulfur-like smell, similar to a rotten-egg.
- Hear: Depending on its size and pressure, a natural gas leak may produce a noise that ranges from next to nothing to a slight hissing or blowing sound to a loud roar.
- See: A leak also may cause dust, dirt or debris to fly, or create blowing or continuous bubbling movement in water. It also can cause a spot of dead or discolored vegetation in an otherwise green area.
Know how to respond to a natural gas leak
When an odor is persistent or seems to be everywhere, or it seems to linger longer than normal for your appliance’s operation, these could be signs of a gas leak inside your home or with an outside line.
Upon detecting such an odor, immediately get everyone out of your home or building, move a safe distance away and then call for help. Because an electric spark can ignite an explosion, remember to follow these tips:
- Do not turn on or turn off electrical switches.
- Avoid using electric appliances such as garage door openers or telephones of any type.
- Do not start up or shut down motor vehicles or any other electrical equipment.
- Do not strike a match.
- Avoid open flames or other ignition sources.
- Move to a location a safe distance away from your home when the odor is outdoors.
- Call 911.
- Stay away until the emergency responders have told you it is safe to return.
Keep your gas meter clear and dry.
