Carbon monoxide (CO) is often called the “silent killer” because it is a gas that is invisible and has no smell. For these reasons, CO often goes unnoticed. CO is a product of combustion, which means that it comes:
- House fires
- broken furnaces
- broken water heaters
- car fumes, or
- gas-powered generator fumes
CO accumulating inside your home can lead to a very dangerous situation for you and your family, which makes it important to have CO detectors installed throughout your home.
Though you may not notice the gas, some symptoms can be the tip-off that something is wrong. These include unexplained headache, dizziness, or the feeling that you want to vomit. Many people in your home may have these symptoms, because CO effects everyone in the household.
Another, much less common way to be poisoned by CO is by ingesting methylene chloride, which is converted in the body to CO. Though uncommon, this ingredient is found in some paint-strippers and bubble light ornaments.
Common methods of exposure
Inhaled? Make sure that everyone leaves the home immediately for fresh air. Call the fire department right away to find the source. They will tell you if and when it is safe to go back inside. Always call the Poison Control Center at 1-800-222-1222.
In the mouth? Do NOT make your child vomit. This can be dangerous. Give water and small snacks to help with an upset stomach. Watch them for coughing or trouble breathing. Always call the Poison Control Center at 1-800-222-1222.
On skin? Remove any contaminated clothing/jewelry and wash the area with soap and water, twice. Call the Poison Control Center at 1-800-222-1222.
