WHERE DO HIGH LEVELS OF CO COME FROM?
High levels of CO can be generated by appliances that are defective or improperly installed or maintained. CO can also enter a home if an appliance venting system or chimney becomes blocked (for example, by a bird’s nest). CO CAN BE DEADLY! High levels of CO can make you dizzy, give you headaches, or cause flu-like symptoms (see the list below). In extreme cases, high levels of or extended exposure to CO can result in brain damage or death. Young children; the elderly; people with heart disease; and those under the influence of alcohol, drugs, or medication are particularly susceptible to CO poisoning.
