Gas Safety At Home

What is carbon monoxide?

Carbon monoxide is an odourless, colourless gas that causes the accidental deaths of about 50 people and seriously injures nearly 200 people in the UK each year. Poisoning by carbon monoxide is almost certainly under-diagnosed, so many people may be suffering from symptoms without realising. Children, pregnant women and their babies and people with cardiovascular diseases are the most at risk.

Because carbon monoxide has no smell, you may wish to install carbon monoxide detectors in your home as a safety measure. These detectors immediately let you know when there's a high amount of carbon monoxide in the air. Be sure to install detectors that meet the British or European safety standards.
