By nature, propane is clear and contains no scent at all. For safety purposes propane. companies add a substance known as ethyl-mercaptan to the propane fuel. Ethyl-. mercaptan has a strong rotten egg, or skunk-like scent, which allows the consumer to. smell it in the case of a leak.
Natural gas is odorless, but it is a common practice to add a distinctive chemical odorant called mercaptan. SÂ·CÂ·UÂ·D has done this so that you can more easily recognize the presence of natural gas, should you have a leak. The chemical odor is frequently compared to the smell of rotten eggs. If you smell something like this, please call us immediately. In the event of an emergency, call the SÂ·CÂ·UÂ·D 24-hour emergency line at 865-453-3272.
