Because propane is virtually odorless and colorless in its natural state, a commercial odorant is added so propane can be detected if it leaks from its container.

Propane is an approved, alternative clean fuel listed in the 1990 Clean Air Act as well as the National Energy Policy Act of 1992.

Propane gas is nontoxic, so it's not harmful to soil and water. Because 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).

According to the U.S. Department of Energy, it could cost consumers twice as much to operate their range, water heater, dryer or furnace with electricity than with propane gas.

Overall propane costs for fleet vehicles typically range from 5 percent to 30 percent less than conventional or reformulated gasoline. Many states offer fuel tax incentives to encourage the use of clean fuels, thus further reducing operating costs.

You should always use a gas grill outdoors in a well-ventilated area. Do not bring propane cylinders indoors or into an enclosed space such as a garage or basement.

Propane is used on 660,000 farms for irrigation pumps, grain dryers, standby generators and other farm equipment. It is an essential fuel for crop drying, flame cultivation, fruit ripening, space and water heating and food refrigeration.

Propane-powered forklifts outperform electric forklifts in both indoor and outdoor applications. They have demonstrated the ability to lift, push and pull heavy loads at full capacity, up and down inclines, for longer periods and with improved ground speed when compared with electric forklifts.

Approximately 97% of the propane supply used in the United States is produced in North America, and 88% of that is produced in the United States.
