A gas leak can be a major cause of concern and tragedy if unnoticed, but what exactly is a gas leak and how does it occur? What are the common signs of an LPG (Liquefied Petroleum Gas) gas leak?

LPG or propane is stored under high pressure. When this stored pressurized gas is released by opening the cylinder tap, it turns into a liquid that immediately vaporizes because of its temperature. As the pressure is released, the boiling point of LPG reduces creating small droplets of liquid.

It's these tiny droplets in gas form that you see coming out from the top of the cylinder or piping equipment when there are signs of a gas leak. These droplets immediately evaporate when exposed to air, leaving no trace of the tiny amount of liquid.
LPG is colourless and odourless; it is not always easy for people to detect the presence of LPG in their surroundings. This makes it all the more important to be aware of the common signs of an LPG gas leak.
Five signs of an LPG gas leak
- Loud roaring sound from the cylinder or pressure vessel
In certain cases, it is possible to hear a loud roaring sound when there is a large leak from the tank in your house. This noise is produced because of air being drawn into the cylinder or pressure vessel due to the high rates of gas leakage.
- Hissing noise from pipelines or appliances
Have you noticed a hissing noise around your cylinder storage area or piping equipment? This sound is indicative of large amounts of gas seeping through very tiny openings (micro leaks). It may also be indicative of LPG boiling at low pressures and emitting the gas.
- Slippery floor near cylinder or appliance area
If you notice your floor becoming slippery in and around areas where LPG cylinder storage and appliances are kept, then it could be because of minute droplets of LPG coming out from the openings when there is a leak. This slippery surface can lead to accidents if not detected early.
- Excess gas coming out of water pipes
If there is a gas leak, it's possible for the gas in your house to seep into the water system and also escape through drains. This may lead to excess bubbles in water or even a build-up of pressure that can open up drain pipes causing excess gas to escape.
- The odour of rotten eggs
LPG is mainly composed of propane and butane. When these components escape into the air, it can produce a strong odour that resembles rotten eggs.
Steps to take when you suspect you have an LPG gas leak
- If you have a leaking gas connection, it's advisable to call the LPG association helpline number 1906 as soon as possible.
- Get everyone out of the house.
- Turn off all possible ignition sources such as gas stoves, room heaters and hot water systems.
- Do not switch on the light switches or call anyone from your home via telephone as you risk igniting a spark that can lead to an explosion.
- Do not smoke or utilize any other source of flame or spark.
- If you suspect a gas leak in your home, make sure to follow the safety precautions that have been outlined above and posted on the LPG cylinder storage area or appliances.
These safety measures must be followed immediately if you suspect LPG gas leaks in your home. It is also advisable to do frequent checks on your gas tanks, as there will most likely be early notification warnings.
