Carbon Monoxide – the silent killer

Carbon MonoxideCarbon Monoxide (CO) is an extremely poisonous gas that can be present in the fumes from the combustion of fuel’s which aren’t burnt under the correct conditions. Fuels such as gas, oil,  solid mineral fuel and biomass all have the potential to emit CO. The gas cannot be seen, smelled or tasted making it difficult to detect.

Protect yourself from CO

CO alarms should be regularly tested and should not be regarded as a substitute for regular maintenance of the appliance and chimney.

The symptoms of carbon monoxide poisoning

The early symptoms of CO poisoning are usually similar to common ailments such as upset stomach, tiredness and flu.

The common symptoms can include:

  • Headaches
  • Breathlessness
  • Nausea and/or vomiting
  • Dizziness or Collapse
  • Chest and/or stomach pains
  • Erratic behaviour and/or Visual problems

Actions to take in a CO emergency

If you suspect fumes are escaping from your combustion appliance into your home, or your carbon monoxide alarm goes off.

  • Turn the appliance off.
  • Open doors and windows to ventilate the building.
  • Leave the building immediately and don’t return until your appliance or boiler has extinguished and the air in the room is clear.
  • If you feel unwell go to your Doctor,  or call one of the following:
    • call NHS Direct on 111 (in England)
