The UK Health Security Agency has recently published a blog on the invisible danger of Carbon monoxide (CO), a colourless, odourless gas that you cannot see, smell or taste – but it can kill. 

Around 20 people die each year in England and Wales from unintentional carbon monoxide poisoning, with many more hospitalised. 

Smaller rooms containing CO sources, such as fuel-burning cookers and fireplaces, are particularly at risk, as the pollutant concentrates more quickly in confined spaces. 

Because carbon monoxide is invisible and has no smell, recognising the symptoms is crucial. Watch out for: 

• headache / dizziness
• feeling or being sick
• feeling weak
• confusion
• chest and muscle pain
• shortness of breath

There are several straightforward steps households can take to protect themselves: 

• Install CO alarms
• Use ventilation wisely
• Service your appliances annually
• Watch fro warning signs

Individuals who think that a gas appliance is leaking carbon monoxide should call the free National Gas Helpline immediately on 0800 111 999. The service is available 24 hours a day, 7 days a week.
