Carbon Monoxide or CO Poisoning

carbon monoxide Harborne Edgbaston Moseley Kings Heath
Carbon Monoxide or CO Poisoning 

  • A gas which is odourless, tasteless and colourless. 
  • Can occur where any source of fuel is burnt incorrectly i.e. without sufficient oxygen. 
  • If breathed in it is harmful and sufficient quantities are poisonous. Contrary to popular belief, it is not just old poorly maintained gas appliances that are at risk, coal fires and sealed fires e.g. Rayburn fires are amongst the largest contributors to CO poisoning. 
Despite scares carbon monoxide poisoning is very rare and can be eliminated by regular servicing, testing, CO detector alarms or boiler up-grades/ replacements. Adequate ventilation and correct flue installation/ maintenance is the key to eliminating the problem of carbon monoxide.
