Propane is a hydrocarbon (C3H8) and is sometimes referred to as liquefied petroleum gas, LP gas or LPG. Propane is produced from both natural gas processing and crude oil refining.
The propane industry has developed numerous methods to make the transport and use of propane safe:
- Propane equipment and appliances are manufactured to rigorous safety standards.
- Propane has a narrow range of flammability when compared with other petroleum products and has the lowest flammability range of any fossil fuel. In order to ignite, the propane/air mix must contain from 2.2 percent to 9.6 percent propane vapor. If the mixture contains less than 2.2 percent gas, it is too lean to burn. If it contains more than 9.6 percent, it is too rich to burn.
