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?
- 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.
- Keep LPG appliances and fittings in good condition. Make sure they are checked regularly for any deterioration, including corrosion or minor leaks.
- Use only equipment and parts specifically manufactured and approved for LPG.
- Use the correct type of hose. Do not make up temporary connections.
- Keep cylinders secure during transport.
- 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.
For more detailed safety information, please see our .
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.
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.
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? How about my 45kg 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. The suitable regulator is available from our retailers.
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.
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
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
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.
