Propane, also known as liquid petroleum (LPG), is a hydrocarbon produced during natural gas processing and crude oil refining. Listed by the 1990 Clean Air Act as one of the cleanest burning fossil fuels available, it's virtually odourless and clean burning. Because it's considered nontoxic and doesn't contaminate soil or water, it's considered an ideal "green" fuel. As a fuel source, it's ideal for use with barbecue grills, stoves and fireplaces. While larger tanks are available for home heating purposes, a smaller 20 gallon tank is typically used for the barbecue or fireplace. If the tank is empty, there are certain methods you should employ while filling it.

Things you need
- Propane tank "nanny"
- Propane cylinder plug
Rest the propane tank in a propane tank caddie or "nanny" in the boot of your car. Available through propane tank suppliers such as U-Haul, the "nanny" secures the tank in an upright position and prevents it from falling or rolling during travel.
Close the cylinder valve and seal with a plastic plug. Even if the cylinder appears to be empty, residual propane settled at the bottom of the tank will expand with temperatures and may escape from the tank. A plastic plug, available through propane suppliers, protects cylinder threads and prevents propane from leaking into the car interior.
Transport the propane tank to a refill station. Many gas stations and garden centres have filling stations where a trained attendant will refill the propane tank. Never attempt to fill or modify the propane tank yourself.
Ask the attendant to inspect the propane tank. If it's damaged, rusted or doesn't have an overfill protection device (OPD), exchange it with the refilling station. Most stations have replacement tanks that are inspected and up to code. According to the National Fire Protection Association, an OPD shuts off the filling device when the tank reaches 80 per cent capacity. As of April 1, 2002, an OPD is required on all propane tanks between 1.81 and 18.1 Kilogram capacity, which helps to prevent propane leaks and potential explosions.
Check the tank for any leaks if you smell propane. While the leak can simply be nothing more than residual from the valve, as additional security, you should check before you hook it up. A soapy "bubble test" is a simple yet effective test for leaks. Before the test, close the valve and insert the plastic plug. Make a heavy, soapy solution with dishwashing soap and pour enough over the regulator, valve and threads to coat. A leak will produce bubbles from the aperture. If you find a leak, call the supplier immediately. Do not transport the tank until you receive instructions from the supplier.
Tips and warnings
- Store propane tanks away from the grill or any heat source.
- Do not store inside a residential dwelling such as a basement or garage.
- If you plan to transport a propane tank to a supplier or filling station, make sure the boot temperature is cooler than 120 degrees Fahrenheit.
