Natural gas is colourless, odourless and non-toxic. As a safety precaution, to enable the speedy detection of a leak of natural gas, a chemical that smells like rotten eggs are added to it. The unusual smell is immediately noticeable.

If you suspect there is a gas leak indoors.

Evacuate and move at least 20m away, leaving doors and windows open.

Don’t turn anything electrical on or off.

Call the fire service on 111.
Turn off any gas appliances that are on.
Do not smoke or use an ignition source.
Do not use your mobile phones, cameras or devices.
Turn the gas meter off, if you know where the gas meter is.
Your gas meter is located outside the house. The valve on the service pipe only requires a quarter turn to move from ‘on' to ‘off'. The gas supply is off/closed when it is horizontal to the pipe. Give the valve a 1/4 turn clockwise (i.e. 12 - 3 o'clock) to turn it off.

Do not smoke.
Evacuate the immediate area.
Leave the damaged pipe to vent, keeping it open and free from any materials or equipment.
Leave any ignited gas fires to burn.
