Propane Facts


Propane is a hydrocarbon (C2H2) 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.  It is nontoxic, colorless and virtually odorless.  As with natural gas, an identifying odor is added so the gas can be readily detected.

Propane has a narrow range of flammability when compared with other petroleum products.  In order to ignite, the propane-air mix must contain from 2.2 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.

Propane  won't ignite when combined with air unless the source of ignition reaches at least 940 degrees F.  In contrast, gasoline will ignite when the source of ignition reaches only 430 to 500 degrees F.

If liquid propane leaks, it doesn't  puddle but instead vaporizes and dissipates into the air.

Propane is one of the lightest, simplest hydrocarbon in existence, and, as a result, is one of the cleanest burning of all fossil fuels.

Because propane is nontoxic, propane does not endanger the environment, the placement of propane tanks either above or below ground is not regulated by the Environmental Protection Agency EPA.

Propane is a Good Value
Propane is used in 48 million households as well as many businesses for water and space heating, indoor and outdoor cooking, clothes drying and backup power.

Propane autogas is an approved clean alternative fuel under the Clean Air Act of 1990 and the third most popular vehicle fuel worldwide

Propane is easy to transport and can be used in areas beyond the natural gas mains.  Because it is 270 times more compact as a liquid than as a gas it is economical to store and transport as a liquid.
