Carbon Monoxide

Due to several tragic incidents across Cornwall involving Carbon monoxide (CO) poisoning, we have produced some advice and guidance for businesses and members of the public.

What is Carbon Monoxide?

Continue reading

CO is a colourless, tasteless, odourless poisonous gas produced by the incomplete burning of carbon based fossil fuels including gas, oil, wood and coal. Some appliances which can produce carbon monoxide include gas boilers, cookers, heaters, open fires, wood burners and oil fired boilers.

Signs of CO

Look out for gas appliances burning with a yellow/orange flame that’s normally blue. Also look for extra condensation, pilot lights blowing out, soot and/or yellow stains round appliances.


Being mistaken for flu, viruses or even food poisoning, the most common symptoms include:

  • nausea
  • headaches
  • dizziness
  • tiredness and feeling disorientated

If someone is suffering from these symptoms whilst at home but is fine elsewhere, they may be suffering from CO poisoning.

  • Evacuate the property
  • Dial 999 and ask for the Fire Service, stating potential carbon monoxide poisoning
  • Do not re-enter the property at anytime

In response to a number of serious carbon monoxide (CO) incidents nationally involving campers/holiday makers, Cornwall Fire, Rescue and Community Safety Service and the CO Awareness charity continue to work in partnership to provide CO awareness information to all caravan and camping sites across Cornwall.

A CO aware register has been created to allow Cornwall's camping and caravan sites to provide visitors with educational / awareness information on the dangers of this silent killer.

To become a CO aware site, complete the form below or call 01726 72582: 

Once registered, your campsite will be provided with a starter pack containing a window sticker, poster to display in your reception area and a small supply of CO Aware flyers for all new holidaymakers informing them of the dangers of CO and how to prevent being poisoned. 

If you require more flyers to hand out to visitors, we have provided it below for your convienience:

The Service hopes that you take the time to consider this very important safety issue and join us in making Cornwall safer.
