Gas leaks | WorkSafe

Never operate any electrical switches when a gas leak is suspected – a flick off or on could cause a spark and ignite the gas. Don't use your mobile phone in the area. Turn off all valves to gas appliances if this can be done safely. Turn off the gas supply at the meter or LPG cylinder. Open doors and windows to ventilate the area.Get price
