THINK YOU SMELL NATURAL GAS? If you SMELL a ROTTEN EGG- OR SULFUR-LIKE ODOR, you may have a gas leak. Natural gas is naturally colorless and odorless. We add an odorant called mercaptan to natural gas, which gives it a DISTINCTIVE SMELL, SIMILAR TO ROTTEN EGGS OR SULFUR. In some cases, you can also identify natural gas by sight or sound. If you see blowing dirt, bubbling water or dead vegetation, or hear a hissing or roaring sound, that could be caused by natural gas.
