About LPG

What is LPG?

LPG stands for liquefied petroleum gas, which describes propane and butane gases. When stored under pressure, they become a liquid and take up much less space, making it easy to transport.

Why does LPG gas smell?

As a safety feature, a strong, distinctive odour is deliberately added to LPG gas for the detection of even minor leaks.

How does leaked LPG gas dissipate?

Because LPG gas is heavier than air, any leaked gas will always flow downwards, collect in low spaces and be slow to dissipate without ample ventilation and air movement.

Is LPG gas toxic?

All LPG gas is non-toxic, non-corrosive, clean burning, and non-polluting. However, if inhaled in sufficient volumes it can cause suffocation.

Can I use propane in my car?

Yes, you can use propane in your car; however, most places do not sell straight propane because it is slightly more expensive than blend (propane/butane mix). It is thought that straight propane is better for your car (in both environmental and in performance terms). Some locations in Victoria, South Australia and Tasmania sell straight propane for your vehicle, so next time you’re going past pull in, fill up, and judge for yourself.

How long should a forklift cylinder last?

Approximately 6-10 hours of operational use, depending on the size of the forklift motor and other variables.

How do I get my industrial/forklift LPG gas cylinder changed over for a full one?

If you currently have a Supagas cylinder and account, simply call your local Supagas location and they will come and change it over for you, on the next day guaranteed and often on the same day.

LPG Safety

What are the basic safety rules I should be aware of?

  1. Ensure that fixed LPG gas installations are carried out and serviced by a licensed or authorised gas fitter. This includes work on premises, caravans and boats.
  2. Keep LPG appliances and fittings in good condition. Make sure they are checked regularly for any deterioration, including corrosion or minor leaks.
  3. Use only equipment and parts specifically manufactured and approved for LPG.
  4. Use the correct type of hose. Do not make up temporary connections.
  5. Keep cylinders secure during transport.
  6. Shut off cylinder valve before disconnecting cylinder from the appliance. Conversely when replacing an empty cylinder make sure the appliance isolation cocks are turned off.

How can I tell if my LPG gas cylinder is leaking?

Spray the fittings on the top of a cylinder with a bottle of soapy water when the line is pressurised. If your cylinder is leaking the gas will create bubbles in the soapy water. If this is the case you must turn off the gas supply and contact your gas supplier.

Can I substitute a 8.5kg BBQ cylinder if my 45kg LPG cylinder is empty?

No, you cannot as it is extremely unsafe! The house appliances (eg. hot water system, heater, etc) either will stop working or function very poorly. This poor functioning may lead to improper combustion and the generation of carbon monoxide. Carbon Monoxide is tasteless, colourless, odourless and highly toxic to the home occupants.

Cold Burns

  • Liquid LPG is extremely cold. It is for this reason we must ensure all PPE is strictly adhered to. LPG contacting the skin can cause severe cold burns.
  • Always take care when working with LPG.
  • To treat a a cold burn injury:
    1. Remove contaminated clothing
    2. Gently flush the affected area with tepid water for 15 minutes
    3. Seek immediate medical attention

    LPG for BBQs

    Is LPG the gas used in BBQs?

    Yes, and it is straight propane gas. This gas is also used in heaters, water heating systems, cookers and other applications.

    What can I do if my BBQ gas cylinder is out of date (more than 10 years old)?

    Government regulation requires BBQ cylinders to be tested every 10 years. Supagas can have your cylinder re-tested so that it is good for another 10 years. Just drop in and see us or call your local branch for pricing and other details.

    How can you tell how much gas is left in an LPG gas cylinder if there is no gauge?

    There is no perfect way to tell, but for a general idea, just pour a cup of warm/hot water on the side of the cylinder and because LP Gas is so cold, a condensation line forms and you will be able to clearly see the level of liquid. You can also place your hand at the bottom of the cylinder and it will fill cold due to LP Gas being inside. As you move your hand up the cylinder the coldness will disappear where there is no gas inside the cylinder.

    How can I tell if my LPG gas cylinder is leaking?

    Spray the fittings on the top of a cylinder with a bottle of soapy water when the line is pressurised. If your cylinder is leaking the gas will create bubbles in the soapy water. If this is the case you must turn off the gas supply and contact your gas supplier.

    Do I need a regulator for my 8.5kg BBQ cylinder?

    Yes, every BBQ should have one as regulators control the pressure of the gas available to the BBQ and allows it to come through at a usable flow rate. The control knobs are only used to adjust the actual volume of the gas to the burners.

    How do I get my BBQ gas bottle filled?

    Come into one of our convenient Supagas locations and we can fill it for you. Because we fill from high-pressure tanks it takes only a quarter of the time it does at a service station.

    LCC27 Valve

    Why is the change happening?

    The Type 21 POL connection is an older, basic, valve connection design. There are some more modern safety features which exist in other valves, so authorities legislated that these features should be made available in LPG cylinders under 25L water capacity. State legislation and Australian Standards were changed to make the new valve and connector a legal requirement. Supagas ensures all its activities comply with legislation and standards, therefore, we’ll be changing our BBQ cylinder valves soon.

    What cylinders are involved?

    LPG cylinders under 25 litres water capacity. For Supagas, that means our 8.5kg and 3.7kg SupaSwap cylinders, plus our Heatagas cylinders. Over the next ten years, as each cylinder’s test date expires, it will have the POL valve removed and a new LCC27 valve installed during the retest process. All new cylinders that Supagas purchases from cylinder manufacturers will come with the LCC27 valve already installed.

    When is the change happening?

    From October 1st, 2021, new LPG appliances like barbeques and patio heaters will begin appearing in stores with the new LCC27 appliance connection on the regulator end of the gas hose. To coincide with the release of the new appliance connection, Supagas will begin to stock SupaSwap cages with a combination of the existing Type 21 POL valve cylinders, and the new LCC27 valve cylinders.

    What changes are happening to the connection?

    The connector on the regulator end of the appliance hose will now incorporate a thermal fuse which will stop the flow of gas if the connection is subjected to a fire. The handwheel will now be a larger plastic, female handwheel, with a righthand thread, making it easier for a consumer to make a connection. The valve itself will incorporate an internal back-check valve that will prevent the outflow of gas from the valve unless an appliance hose has been securely screwed to the valve. The valve spindle and bleed screw will be encapsulated so that a consumer can’t screw them all the way out. A spindle or bleed screw that can be screwed all the way out can cause an uncontrolled release of gas that is extremely difficult to stop.

    If the changes are based on safety, does that mean the existing connection is unsafe?

    No, legislation and Australian Standards support the existing POL connection as a safe connection when used properly. Consumers can continue to use their POL appliances with POL cylinders safely, just as they have for decades.

    Will consumers need to buy new appliances to match the new valve?

    No, there is no need for consumers to rush out and purchase new appliances. Cylinders with the existing Type 21 POL valve will still be readily available from every SupaSwap cage. Also, the existing Type 21 POL connection on the regulator end of their appliance hose will still safely screw into the new LCC27 valve.

    Can a consumer use their existing POL cylinder on a new LCC27 appliance?

    If a consumer purchases a new appliance after October 1st, 2021 and it has an LCC27 appliance connection, the consumer must purchase an LCC27 valve cylinder from their local SupaSwap retailer. If they mistakenly purchase a Type 21 POL valve cylinder, they must take it back to their place of purchase and swap it for an LCC27 valve cylinder.

    How do I avoid confusion when purchasing a SupaSwap cylinder?

    When the consumer purchases a SupaSwap cylinder, they simply need to match the cylinder valve with the appliance connection they have on their appliance at home. Colour-coded guidance material will be made available at the place of purchase to assist them with selecting the correct cylinder.

    If I choose the wrong cylinder, can I use an adaptor to make the connection?

    Attempting to use an adaptor between the appliance connection and the valve is illegal and has led to many more incidents in countries overseas where a similar valve connection change was implemented.

    What do I tell a consumer who claims they need a cylinder with an LCC27 valve now?

    To avoid a rush on cylinder demand, the authorities legislated that gas suppliers should start building their stocks of LCC27 cylinders from April 1st, 2021 (Supagas has been doing this). It’s also legislated that new appliances with the LCC27 connector must not be sold into the market until October 1st, 2021. Therefore, there are currently no LCC27 appliances in the market, so there is no need for a consumer to have an LCC27 cylinder until they purchase a new appliance from October 1st onwards.

    LPG and Bushfires

    Which pieces of gas equipment may be affected by bushfires or extreme heat?

    All of the following may be affected by extreme heat:

    • LPG installations
    • Storage tanks
    • Household cylinders
    • Portable camping cylinders

    What should I do with my LPG storage tank/cylinder before the threat of an approaching bushfire?

    • Ensure that the area around the tank or cylinder is free from all flammable materials
    • Ensure that cylinders are in an upright position and secured on a firm, level, and non-combustible base
    • Ensure that safety pressure relief valves of tanks and cylinders are directed away from the building and each other
    • Ensure that household or portable cylinders are not stored indoors, under buildings or stairwells
    • Ensure that all cylinders are stored away from potential ignition sources
    • Ensure that the tank or cylinder isolating valves are accessible and can be easily turned off

    What should I do with my LPG storage tank/cylinder as a bushfire approaches?

    • Turn off all gas appliances
    • Turn off cylinder or tank supply/isolating valve(s)
    • Don’t forget BBQ, caravan, workshop cylinders, or portable camping cylinders
    • DO NOT disconnect or remove household cylinders from their upright position where they are on a firm level non-combustible base, and ensure the cylinders are secured in place with the retention chain (if fitted)
    • If the cylinders are exposed to heat, AND IF ONLY SAFE TO DO SO, hose them down with water to reduce the pressure building up inside the cylinder

    What should I do with my LPG storage tank/cylinder after the threat of bushfire has passed?

    It is NOT safe to turn on storage tanks or cylinders. They should be checked by your gas supplier.

    • Any damage to tanks or cylinders, such as dents or gouges, will affect the cylinder’s integrity
    • Damage to tanks or cylinders may not be visible or obvious
    • The storage tank or cylinder must be checked for damage by your gas supplier
    • If you have damaged tanks or cylinders contact your gas supplier

    Do I need to have my gas systems and appliances checked after the threat of a bushfire has passed?

    Yes; it is NOT safe to use the gas system and/or appliances. Get a licensed gas fitter to check. The heat from the fire may have damaged gas pressure regulators, pipework, or appliances. Damage may not be visible or obvious. Do not use the gas installation or appliances without first engaging a licensed gas fitter to check the integrity of the installation and appliances

    Natural Gas

    Does Supagas supply natural gas cylinders?

    No, we don’t supply natural gas at all.

    What is the difference between natural gas and LPG gas?

    LPG and natural gas are similar in terms of usage, but natural gas cannot be stored and transported as a liquid and therefore is not widely available.

    Can I use LP Gas in natural gas appliances or vice versa?

    No, each type of gas requires different amounts of oxygen to burn properly, so different burners are needed in the appliances. All gas installations and conversions must be carried out by a licensed gas fitter.

    Other Questions

    What type of signage should I have on the gate if different gases are used on site?

    It depends on exactly which gas you have on your site. LPG gas you will require a metal 2YE sign. Phone 13 78 72 to find out more info.
