What is carbon monoxide

Carbon monoxide is a colourless, odourless and tasteless gas that can kill, so don’t be complacent.

Carbon monoxide is produced when some fuels – such as LP Gas, diesel, petrol or natural gas – don’t burn properly. These fuels need a lot of air and the right gas supply pressure to burn safely.

Carbon monoxide is generally not produced in harmful concentrations when fuels burn properly. But faulty or poorly maintained appliances, may produce carbon monoxide. The burning process can be affected by:

  • poor ventilation
  • an appliance flue or exhaust not located correctly
  • the wrong supply pressure
  • dust blocking gas ports

Symptoms of low level carbon monoxide poisoning

  • headaches
  • nausea
  • dizziness
  • breathlessness
  • collapsing
  • losing consciousness
