Common Signs of a Gas Leak

Gas leaks can happen in homes or businesses, anywhere where natural gas is used for heating, cooking or a hot water system. Recognising the warning signs of a leak can help you react quickly, reducing the risk of a serious incident. Here are some of the common indicators:

Smell: A Distinctive Odour

Natural gas has no scent, but a chemical is added to the gas we use to give it a strong odour, often said to be like rotten eggs. If you smell what you think is gas, often near gas appliances, gas lines or the meter, then you should seek help from an emergency local plumber immediately.

Sound: Hissing or Whistling

Gas escaping from a fitting, a pipe or an appliance often makes an audible sound. This can be easier to hear when it’s quiet, such as at night.

Visual Indicators: Plants, Discoloured Flames, etc.

A gas leak can cause visible changes. Some signs to watch for include dead or dying plants near a gas line. Also, check if the flames on your gas hob are yellow or orange instead of blue. Unusual condensation on windows near gas appliances can be another warning sign.

Physical Symptoms: Health Effects

Exposure to gas can have serious consequences for your health. Obvious symptoms can include headaches, feeling ill, dizziness or shortness of breath. The symptoms may appear worse in enclosed spaces or areas with poor ventilation.

If a number of people show symptoms at the same time, especially indoors, leave the area right away. Seek medical help and call your emergency plumber.

What to Do If You Suspect an Emergency Gas Leak

If you think you have a gas leak, follow these steps right away. This will help keep everyone safe and ensure the right professionals are called to handle the situation.

First reactions

  • Leave the building right away. Make sure everyone, including pets, leaves too. Open doors and windows to help ventilate the area.
  • Don’t operate any electrical switches or any device that could potentially create a spark. Even turning a light switch on or off can ignite leaking gas
  • Don’t use your phone inside the property. Make emergency calls from a safe place outside the building.
  • Do not try to find or fix the leak yourself. Professional gas fitters have the equipment and expertise to do this safely.

Who to Contact

Depending on the circumstances, you may need to contact the following:

  • You should call emergency services on 000 if you think anybody has been affected by the gas or there is any risk of the gas igniting.
  • Let your neighbours know if there’s a risk of the leak affecting their property.
  • Call your local plumber or a licensed gas fitter for emergency gas repairs.

Regardless of your situation, always make a point of evacuating the premises and getting professional help. Never take risks if you think you have a gas leak.
