• Carbon monoxide is known as the 'silent killer' due to it being colourless, tasteless and odourless. Early symptoms of carbon monoxide poisoning are similar to flu and may be ignored for what they truly are. If not detected carbon monoxide can kill. Over 40 people a year die due to carbon monoxide poisoning.
  • 1. If your carbon monoxide alarm sounds or you suspect a leak:
    • Stop using all appliances, switch them off, and open doors and windows to ventilate the property
    • Evacuate the property immediately; stay calm and avoid raising your heart rate
    • Call the Gas Emergency number on 0800 111 999 to report the incident, or the Health and Safety Executive (HSE) Gas Safety Advice Line on 0800 300 363
    • Donʼt go back into the property; wait for advice from the emergency services
    • Seek immediate medical help; you may not realise youʼve been affected by the carbon monoxide and going outside into fresh air wonʼt treat any exposure by itself
