"In your home, wherever you have a closed space and there is some form of heating going on," said Ranne, "Anytime you have a closed space you have to be afraid of carbon monoxide poisoning."
Ranne said the silent killer is odorless and doesn't cause symptoms until it builds up in your blood."What happens then is the body cant get enough oxygen as the carbon monoxide replaces the oxygen in the blood cell," said Ranne.
Once carbon monoxide poisoning occurs Ranne said it's vital to get out of the toxic space and into fresh air."The symptoms of carbon monoxide poisoning are nausea, headache, which progresses to dizziness and then at times is can lead to coma," said Ranne.
He said ventilation is key to keep this from happening to you and your family.
"The best prevention for carbon monoxide poisoning is adequate ventilation," said Ranne, "The number two thing is to not let children work with space heaters or to burn in a closed space."
He said a small build up of carbon monoxide can be tolerated with proper ventilation.
