Carbon Monoxide (CO) Awareness

What is Carbon Monoxide (CO)?

Carbon monoxide is a colourless, odourless, and tasteless gas. You can’t see, smell, or taste it — which makes it extremely dangerous. It’s often called the “silent killer.”

Where does it come from?

Carbon monoxide is produced when fuels don’t burn properly. Common sources include:

• Gas boilers and cookers
• Open fires and wood burners
• Oil or coal heaters
• Portable heaters and generators
• Blocked chimneys or flues
• Running a car in an enclosed space (like a garage)

Poor ventilation or faulty appliances increase the risk.

Signs and Symptoms of Carbon Monoxide Poisoning

Early symptoms can feel like flu (without a fever):

• Headache
• Dizziness
• Nausea or vomiting
• Tiredness
• Shortness of breath
• Confusion

Severe exposure can cause collapse, unconsciousness, or death.

Important Safety Advice

• Install a carbon monoxide alarm in your home.
• Have gas appliances serviced annually by a qualified engineer.
• If you suspect carbon monoxide, get fresh air immediately and call emergency services.
