Propane Facts

Propane is a nontoxic gas. In comparison, methanol, gasoline, diesel and ethanol are listed by the EPA as toxic liquids. Methanol mixes readily with groundwater and is virtually unremovable once it enters the soil or water supply. Propane is released as a gas and will not contaminate soil or groundwater supplies. Therefore, propane is exempt from the EPA's tough underground storage regulations.

Propane is considered a safe motor fuel by the federal government. School buses run on propane. Propane vehicle tanks are tested to four times the normal operating pressures, and these tanks are 20 times as puncture-resistant as gasoline, methanol or ethanol vehicle tanks. Of methanol, ethanol, CNG or propane, propane has the lowest flammability range--a safety advantage.

Made in the USA:
Over 88% of the current propane use in this country comes from our own sources. Of this, 70% comes from the processing of natural gas. The U.S., Canada and Mexico have extensive natural gas reserves. The majority (75%) of imported propane comes from Canada.

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

Over-filling Precaution:
Since 1984, all new propane tanks are required to have a device that shuts off the filling process when the tank reaches 80% of its liquid capacity. This allows for changes in fuel volume caused by temperature changes such as when a car is driven from a frigid street into a heated garage.

Vehicle Tanks:
Propane vehicle tanks are constructed from carbon steel under a code developed by the American Society of Mechanical Engineers (ASME). A propane tank is 20 times more puncture-resistant than a typical gasoline, methanol or ethanol tank. In addition, a properly installed propane tank can actually add to the structural strength of a vehicle. Propane tanks are tested at four times their normal pressure of 135 psi while CNG tank's normal pressure is 3600 psi.
