It’s crucial to act quickly in a gas emergency. These are the steps you need to take to stay safe:
Turn off the gas emergency control valve at the meter, unless the meter is located in a basement or cellar or at the LPG bulk tank or storage vessels
Extinguish all naked flames and don’t smoke
Don’t operate electrical switches including turning light switches on or off because this can ignite escaping gas
Get fresh air immediately; make sure you open all doors and windows to ventilate the area
Contact the relevant National Gas Emergency service number. Natural Gas - 0800 111 999 / LPG – contact number on storage vessel or meter
If the attending emergency operative identifies an issue with any gas appliances, follow their advice concerning the use of the equipment. Where advised, contact a Gas Safe registered engineer to fix the appliance and check it’s safe
If you’re feeling unwell, visit your GP or hospital immediately and let them know you may have been exposed to carbon monoxide
Don’t turn the gas supply on again until it’s been checked by a Gas Safe registered engineer
