The Original Safety Messages

» Signs of a Gas Leak Message » For your protection, SoCalGas adds a distinctive odor to natural gas, so leaks can be more

readily detected. However, you should not rely on your sense of smell alone to determine if there is a gas leak.  It’s important to know that any of the following signs may indicate the presence of a gas leak: 

A damaged connection to a gas appliance. An unusual sound, such as hissing, whistling or roaring near a gas appliance or pipeline. Dead or dying vegetation (in an otherwise moist area) over or near pipeline areas. A fire or explosion near a pipeline. Dirt or water being blown into the air. Exposed pipeline after an earthquake, fire, flood or other disaster.

» Special pipeline markers show the general location of most major pipelines, but do not indicate the exact location, depth or number of pipelines in the area.

» *Some persons may not be able to smell the odor because they have a diminished sense of smell, olfactory fatigue (normal, temporary inability to distinguish an odor after prolonged exposure to it) or because the odor is being masked or hidden by other odors that are present, such as cooking, damp, musty or chemical smells. In addition, certain conditions in pipe and soil can cause odor fade – the loss of odorant – so that it is not detectable by smell. For more information on odor fade, please visit socalgas.com/safety.
