What to do in an emergency
Make sure you know what to do and who to call in an emergency. If you suspect a Carbon Monoxide leak, stop using the appliance until it has been checked by either a CORGI registered installer if it is a gas appliance or by another relevant professional (contact OFTEC or HETAS for further details).
You should open windows to ventilate the area, leave the room to get some fresh air and seek medical attention.
If someone is seriously ill from Carbon Monoxide poisoning it is vital that they are removed immediately from the contaminated area, placed into the open air and given pure oxygen, if available. Victims should be kept at rest, avoiding exertion. You need to call for medical help urgently.
If you receive medical attention, be sure to state that you suspect Carbon Monoxide poisoning to ensure you receive appropriate treatment, such as a breath or blood test.
If you smell gas then call:
0800 111 999 for England, Scotland and Wales
0800 002 001 for Northern Ireland
01624 644 444 for Isle of Man
01481 749000 for Guernsey
01534 755555 for Jersey
If you are calling from a mobile phone then go outside first. Do NOT smoke, do NOT turn light switches on or off and do NOT do anything to create a spark. Turn off the supply at the meter. If you do not have to switch on a light to do so, open doors and windows and wait outside for the emergency engineer to arrive.
