What does gas smell like?

Natural Gas is typically odourless and colourless. It has a chemical added to it called Mercaptan that gives off the smell of rotten eggs. It is quite strong and is purposely added to Natural gas to alert you if there is a gas leak in your home.

Gas leaks are hard to miss as you will definitely know if there is a smell, due to the added Mercaptan. Without this chemical, there would be no way to know if toxic omissions are in the air.

Is it bad if you can smell gas in your house?

It is considered bad if you notice the smell of gas in your house. Gas is meant to be contained in the right piping and not out in the open air to be inhaled. It is a dangerous chemical and is highly flammable. If a flame is ignited in close proximity, then you are at risk of an explosion occurring. Even the slightest leak can silently and quickly fill up an entire room.

A gas leak is considered a plumbing emergency and should be attended to immediately by your Australian gas distributor as well as a licensed plumber who is able to carry out gas works.

What does it mean if I smell gas in my house?

Smelling an odour similar to rotten egg could be an indication of a gas leak. There may be a hole in a gas pipe or a gas appliance or you can find your gas connection could be faulty. The gas supply to your meter may have a leak or you may need to check the pilot lights of the gas burners.

Whatever the reason is for the hissing noise coming from your cooktop or the smell of rotten cabbage that you can't seem to get rid of, it's important to get it checked sooner rather than later.

Can a gas leak make you feel ill?

Smelling something gassy is not a good thing for your life or property. It can also be hazardous to your health and is particularly harmful to those who have respiratory problems, young children and the elderly.

As soon as you suspect an issue with your gas appliance, you need to move away from the source of the gas leak immediately. Keep windows and doors open to provide fresh air inside your home and sufficient ventilation.

What to do if you can smell gas outside your home?

You need to contact your gas distributor and organise an emergency appointment if you can notice a leak coming from the gas meter. Keep safe by staying away from the exposed gas.

Contact a professional Gasfitter

For all gas leak emergencies, you need to call a plumbing service that specialises in gas works.

A licenced gas fitter is able to help with all major gas leaks and installation of appliances. They are able to install and disconnect all gas appliances and pipes and assist you with your gas meter needs whilst keeping your family and home safe.
