Warning Signs

Warning signs of Carbon Monoxide

Boilers, hobs and fires can fail quickly and without warning. You may not have time to notice any problems or react, as high levels of CO can kill very quickly. There is no substitute for an audible alarm.

However signs which may indicate carbon monoxide emission include:

  • Yellow or orange rather than blue flames (except for ‘coal effect’ fires)
  • Soot or yellow/brown staining around appliances
  • Pilot lights that frequently blow out
  • Increased condensation on windows

Bad ventilation / good ventilation
