What is Carbon Monoxide?

Carbon monoxide (CO) is a poisonous gas. You can't see it, taste it or smell it. It's produced when carbon-based fuels like gas, oil, wood and coal don't burn properly.

These fuels are safe to use. The danger comes only when a fuel doesn't burn as it should, producing excess CO. When CO gets into the body, it stops the blood from carrying oxygen to your cells, tissues and organs. It can kill quickly, without warning.

If you have appliances that run on fossil fuels, make sure they're serviced and maintained regularly by a competent person. You can find a registered Gas Safe installer here.
