**Millions at Risk from Silent Killer: Symptoms to Watch Out For**
Experts are sounding the alarm on the dangers of carbon monoxide poisoning, as a new study reveals that millions of people are unknowingly at risk of being silently poisoned by their gas appliances in the UK. The independent charity CO-Gas Safety has estimated that as many as one in five homes in Britain have dangerous levels of this colourless, odourless gas. Shockingly, even less than 2% of carbon monoxide in the air can lead to death in under three minutes or cause severe long-term health issues.
One of the most concerning aspects highlighted by the study is that one in seven people do not have their gas boilers and appliances serviced annually, with some never having them checked at all. This lack of awareness poses a significant threat, as carbon-fuelled appliances, when not properly maintained, can release carbon monoxide into living spaces without any detectable signs. Although over 80% of people claim to have a carbon monoxide alarm installed, more than half admit they do not check if it is functioning, and a third have resorted to removing the batteries when it beeps.
CO-Gas Safety is calling for the gas emergency service to not only shut off gas appliances but also conduct tests on home emissions and appliances. President Stephanie Trotter stressed the importance of regular servicing to prevent potential tragedies, especially given the link between rising energy bills and decreased affordability for maintenance. Additionally, Trotter highlighted that carbon monoxide alarms are essential but only effective when operational, and they can only alert to dangerously high levels of the gas.
In the UK, approximately 30 individuals die from carbon monoxide poisoning annually, while around 4,000 are treated in A&E departments. However, the actual figures are likely higher, as evidence of carbon monoxide in the body dissipates rapidly. Prolonged exposure to low levels of this toxic gas can lead to lasting health issues such as brain damage and heart problems. Various household appliances, including gas cookers, boilers, and wood-burning stoves, can emit carbon monoxide, resulting in symptoms like headaches, dizziness, and confusion.
Despite the potential dangers, a new study has revealed that nearly three-quarters of Brits would not evacuate their homes promptly upon hearing a carbon monoxide alarm. Furthermore, more than a third believe that low-level exposure to carbon monoxide is tolerable, while two-thirds are unaware of its correlation with heart problems and hearing loss. The lack of understanding extends to the sources of carbon monoxide, with many unaware that wood burners, water heaters, and even barbecues can produce the gas.
Stephanie Trotter from CO-Gas Safety emphasised the severity of carbon monoxide poisoning, reiterating that it is imperceptible to human senses yet can be fatal within minutes. She urged vigilance and stringent testing procedures in homes, particularly as recent studies suggest that 20% of households in Britain may have harmful levels of carbon monoxide. Trotter highlighted the importance of immediate action if any symptoms of carbon monoxide poisoning are suspected, underscoring the need for public awareness and preventative measures to mitigate risks effectively.
If experiencing symptoms or suspecting exposure to carbon monoxide, experts advise not hesitating to seek help by dialling 999. Early detection and swift action are crucial in preventing tragic outcomes associated with carbon monoxide poisoning. Symptoms such as headaches, dizziness, and feeling unwell, especially if multiple individuals in the same household exhibit similar signs, should not be ignored. By raising awareness and promoting proactive measures, the impact of this silent killer can be significantly reduced to safeguard the health and wellbeing of individuals and families across the UK.
