Most Irish people are unaware of the connection between burning fossil fuels and the risk of carbon monoxide (CO) poisoning, new research has found.

CO is a poisonous gas, however, it is colourless and odourless. It is produced when fossil fuels, such as oil, gas and coal, do not have enough oxygen to burn completely.

If inhaled into the body, CO combines with the blood, preventing it from absorbing oxygen. If a person inhales CO over a period of time, they are at risk of becoming seriously ill or even dying. Around six people die every year in Ireland as a result of accidental CO poisoning.

However, a survey of 1,000 adults released as part of Carbon Monoxide Awareness Week, revealed low levels of consumer awareness when it comes to the connection between CO and the burning of fossil fuels.

For example, just one in three people are aware that oil and gas can produce CO when burned, while only one in four are aware that coal, kerosene and bottled gas can produce it.

Meanwhile, just one in five people know that charcoal, peat and turf can produce the poisonous gas, while only one in seven know that burning wood and wood pellets can produce it.

In order to prevent CO, fuel burning appliances, such as gas boilers, should be serviced on an annual basis and chimneys, vents and flues should be kept clear.

According to the research, almost three in four people are aware of the importance of regular servicing of these appliances, however for almost six in 10 people, the cost of such a service is a prohibiting factor.

Furthermore, when asked when was the last time they had their heating appliance serviced, 8% said that to their knowledge, it had never been serviced, while 15% said they did not know.

"This research shows that everyone needs to be more aware that every fossil fuel when burned has the potential to produce CO. CO poses a very real threat to people's lives. Regular appliance servicing and keeping vents, flues and chimneys clear are extremely important to ensure the safety of family members and loved ones," commented Dr Paul McGowan of the Commission for Energy Regulation (CER), which organises this event.

As part of Carbon Monoxide Awareness Week, which runs until September 29, people are being reminded of the importance of installing a CO alarm in their homes.

Symptoms of CO poisoning can include cold-like symptoms, headaches, dizziness, chest pains, diarrhoea and lack of energy. For more information on CO, click here
