What is propane?

Propane — sometimes known as liquefied petroleum gas, or LPG — is a gas normally compressed and stored as a liquid. It is nontoxic, colorless, and virtually odorless; an identifying odor is added so it can be detected. When used as vehicle fuel, propane is known as propane autogas. Propane is most commonly used for home and water heating, for cooking, and as fuel for engine applications such as forklifts, mowers, generators, and irrigation engines. However, its applications are rapidly growing due to new technology developments.
