What is Odorant?

Natural Gas and Propane are nearly odorless and undetectable gases when extracted from the Earth. When undetectable, the flammable and volatile nature of these gases becomes hazardous to anyone near it. In order to warn those exposed to unodorized gas, Mercaptans (odorant) are added to natural gas and propane to give a pungent and easily detectable odor.
