Outdoor Signs
Look outside the home as well for evidence of a gas leak, including:
Visible air movement: A gas leak from an underground pipe can cause dirt to be thrown into the air or plants to be blown, as if by a breeze. Unusual air movement from the ground near the home is a possible sign of a gas leak.
Bubbles: A leak in a gas pipe can sometimes cause bubbling in moist ground areas around the home. A water puddle that bubbles may be hiding a leaking underground gas pipe.
Dying plants: Plant life near a gas leak will become sickly and eventually die. While plants can certainly wilt and die due to a variety of reasons, plants that die without an obvious cause can indicate a gas leak. A natural gas leak blocks a flower's source of oxygen and fruits and vegetables will change color when they come in contact with natural gas. If you see dead or discolored plants surrounded by healthy green plants, it is worth investigating.
Dry spot inside an area of moist ground. A gas leak can dry out moist ground, so if you see an unusual spot of dry earth within a moist area, it may mean that leaking gas from an underground pipe is drying out the soil.
Ground on fire. A clearly defined blue or yellow flame coming from the ground, or a flame appearing to hover above the ground, is a clear sign of a gas leak in an underground pipe. Move far away from the area and call the authorities immediately.
