Print this article Share

Carbon monoxide is known as the silent killer as it has no smell, taste or colour, thus giving no warning of its potentially fatal presence. Our guide will help you tell if carbon monoxide is present in your home, and show you how to prevent it.

Carbon monoxideCarbon Monoxide, also known as CO, is a colourless and odourless gas that is highly poisonous. About 40 people die every year in Ireland from accidental CO poisoning in the home. Carbon monoxide is formed when organic fossil fuels such as oil, gas, turf or coal do not burn fully. When it is inhaled into the body it prevents the blood in your system from absorbing oxygen. If a person is exposed to carbon monoxide over a long period of time, it can cause serious illness or death.

Did You Know?

Up until the late 80’s, canaries were used in coal mines to detect the presence of dangerous gases such as carbon monoxide. If the bird showed any signs of distress, it was time to get out of the mine. Thankfully, the introduction of carbon monoxide alarms has retired the canaries from the mines
