Expert warns of dangers of carbon monoxide

Apr 19 2006

As parts of the UK continue to experience cold temperatures the lead clinical toxicologist at Guy's and St Thomas' and international poisons expert, Dr Alison Jones, has warned people to be alert to the dangers of carbon monoxide poisoning caused by faulty heating appliances.

Every year around 50 people die in their own homes as a result of inhaling carbon monoxide gas accidentally. These deaths could be prevented by knowing how to avoid exposure to the deadly gas, she warns.

Dr Alison Jones says:

"There are lots of myths surrounding carbon monoxide poisoning, particularly that it is mainly people who live in rented property who are most at risk. In fact more people are killed in owner occupied properties.

"Others think that you can only get carbon monoxide poisoning from gas fires. That is completely wrong, you are at risk from any fossil fuel burning appliance so make sure that you keep all heating appliances including boilers and coal fires in good order and consider getting a British Safety Standard carbon monoxide detector."

She urges people to make sure that their rooms are well ventilated, get all heating appliances checked regularly and make sure that chimneys and flues for fires are swept and kept clear.

Dr Jones says:

"Carbon monoxide can be absolutely deadly and is difficult for people to spot as it is colourless and doesn't smell of anything. However there are some telltale signs which people should look out for.

• Flames that are normally blue turning yellow or orange
• Smoke coming into the room because of a blocked chimney
• Coal or wood fires burning very slowly or going out
• Sooty stains appearing above appliances regardless of what they are burning.

"Most importantly if you feel dizzy, sleepy or sick for no obvious reason you should switch the appliance off, leave the room and see a doctor as soon as possible. Chest pains, nausea, vomiting and headaches can also be signs of carbon monoxide poisoning."
