LPG (propane) smells because an odourant - Ethyl Mercaptan - is added to the gas to make it easier to detect a leak. In their natural state, LPG (Propane and Butane) and Natural Gas (Methane) are all odourless gases. The distinctive smell that people associate with these gases is actually added to them as a safety measure.
Natural gas is odorless in its natural form. Before it arrives at your home, an odorant called mercaptan is added to it, so you can smell the gas immediately if a leak occurs. Mercaptan makes the gas smell like sulfur or rotten eggs. Everyone in your family should learn to recognize this smell.
