PREVENTION
Install a carbon monoxide detector on each floor of your home. Place an additional detector near any major gas burning appliances (such as a furnace or water heater).

Many carbon monoxide poisonings occur in the winter months when furnaces, gas fireplaces, and portable heaters are being used and windows are closed. Make sure you have any heaters and gas-burning appliances regularly inspected to make sure they are safe to use.
