Odor Fade: Do Not Rely on Your Sense of Smell Alone to Detect Natural Gas
This notice is to provide members and contractors who work on natural gas piping, equipment, and appliances with additional safety information on natural gas and the potential for odor fade.
The Energy Cooperative odorizes the natural gas that is delivered to you. Even though a distinctive odor (smells like rotten eggs) is added to natural gas to assist in the detection of leaks, you should not rely solely on your sense of smell to determine if a gas leak exists or if natural gas is present. You may not be able to detect the odorant because of a weakened sense of smell or because the odorant is masked by other odors. Rare conditions, such as odor fade (loss of odorant), could occur which may cause the odor to diminish so that it is not detectable.
