difference between carbon dioxide & monoxide
Carbon Monoxide is produced from gas appliances in your home. Carbon Dioxide is produced from the exhaust fumes from your automobile. Either of these gases can be harmful to a human. These gases can be even more harmful to small animals in your home. Depending on the size of your home you should have a carbon monoxide detector on every level of your home.
carbon monoxide is the dangerous one. carbon dioxide is complete combustion, monoxide incomplete. you exhale carbon dioxide when you breathe out. i would repair the glass myself but don't know where to buy the stuff.
