More than 500 Americans die each year from carbon monoxide (CO) poisoning and thousands more are treated in hospitals for related symptoms. This odorless, colorless and tasteless gas is often referred to as “the silent killer” and can cause sudden illness or death if inhaled.
When a person breathes air containing carbon monoxide, it soon replaces the oxygen in their blood. This quickly kills off cells and starves vital organs of oxygen, according to silentshadow.org.
Common symptoms of poisoning include headache, dizziness, weakness, nausea, vomiting, chest pain and confusion. High levels of carbon monoxide ingestion can also cause loss of consciousness, coma or even death. A majority of deaths occur when people are asleep, as they inhale the CO, lose consciousness and never wake up.
The gas can be emitted from common household items such as furnaces and car exhausts, even refrigerators. Therefore, it’s likely everyone has an item in their home or office that can cause carbon monoxide pollution.
Other sources of CO leaks are non-electric furnaces, gas water heaters, generators, fireplaces and wood stoves, space heaters, gas dryers, charcoal grills, lawnmowers and cars. Carbon monoxide is a by-product of incomplete combustion. Any fuel-burning device has the potential to produce dangerous levels of CO gas.
Carbon monoxide can only be detected with a carbon monoxide detector, such as an alarm. These are available in plug-in, battery-operated, or hardware models. As a precaution, it’s best to place a carbon monoxide alarm on each level of your home.
Twenty-five states have laws requiring carbon monoxide detectors in residential buildings. To learn what your state requires, visit:
