What should I do if I smell gas at home?

  • Ensure all gas appliances are switched off
  • Don't smoke or use a naked flame
  • Don't switch anything electrical on or off. E.g. doorbells, switches or appliances
  • Open windows and doors to let the gas disperse
  • Check your appliances to see if the gas has been left on without being lit

If you've taken all these precautions and you still smell gas, you should turn off the gas at the meter and call the Bord Gáis 24-hour emergency number 1850 20 50 50.

What gas safety precautions should I take?

  • If undertaking alterations to your home which may affect the safety or efficiency of your gas installation, get the advice of a competent Registered Gas Technician. A list of Registered Gas Technicians in your area is available on the Register of Gas Installers of Ireland .
  • Never block a ventilator which is there to ensure a safe supply of air.
  • Gas boilers and appliances should be installed in accordance with Irish Standard 813: 2002 'Domestic Gas Installations', by a competent Registered Gas Technician.
  • Use appliances only for the purpose for which they were designed, i.e. do not use a cooker to heat a room.
  • Never use any gas appliance if you suspect it might be faulty. Have it checked.

Where can I find a Registered Gas Installer?

The Register of Gas Installers of Ireland has a full list of gas installers by area.  It is recommended that you contact at least three installers to compare cost.

How do I turn the gas off and back on?

When turning off the gas, you should first ensure that all gas appliances and pilot lights are switched off.  Next you need to turn off the safety shut off valve, which is normally located within your gas meter box, outside the house.  The valve is off when it is at right angles to the pipe.

To turn the gas back on, simply return the safety shut off valve to its original position, which is in line with the pipe.

If you have any difficulty reaching or turning the valve, you should contact Bord Gáis Networks on 1850 200 694.

What is Carbon Monoxide?

Carbon Monoxide is highly dangerous.  It is a colourless, odourless, and tasteless gas that can cause illness and even death.  Carbon Monoxide can be produced by the burning of fossil fuels, including by natural gas appliances, where there is poor ventilation and/or where the appliance is poorly installed, badly maintained or damaged.
