Best Answer

Natural Gas itself is colorless and almost odorless - A chemical odorant (t-butyl mercaptan) is added to the Natural Gas so the leak can be detected quickly.

The smell of t-Butyl Mercaptan is distinct, once you smell it you will always know it...sort of a rotten cabbage smell. Sometimes a related Chemical, Thiophane, is used...with a rotten egg smell.
