Carbon Monoxide Dangers from heating appliances and generators used indoors

Date published: 26 January 2025

With some homeowners continuing to experience electricity issues across the province, we wish to highlight the following guidance.

Carbon Monoxide is a colourless and odourless gas that can kill quickly without warning.

Carbon monoxide is produced by the incomplete combustion of solid, liquid, and gaseous fuels. 

Using equipment such as kerosene heaters, charcoal grills (BBQs) and portable generators in doors can cause CO levels high enough to result in CO poisoning.

Only equipment designed to be used indoors should be brought inside the home.

Where any fuel burning equipment is used indoors there must be good ventilation and in conjunction with carbon monoxide alarm. Always follow the manufacturers guidance.

Symptoms of CO poisoning can feel like every other day illnesses, and include Headaches, Nausea, Breathlessness, Dizziness, Collapse, and loss of consciousness. 

If affected, you should:

• Open doors and windows for ventilation and go outside into the fresh air;
• Go to your GP or nearest A&E department;
• If its urgent call 999 for an ambulance; and
• Call the relevant emergency advice line: Gas Emergency Service (24 hours) 0800 002 001Oil (OFTEC) 0845 65 85 080.
