Carbon Monoxide (CO) Alarms and CO Poisoning
Never Ignore an Alarming CO Alarm!
It is warning you of a potentially deadly hazard.
A working smoke and carbon monoxide alarms are the most important device you can have in your home. They provide essential early warning of a problem so you and your family can safely escape.
Requirements for carbon monoxide, or CO, detectors (alarms) went into effect in 2005 for all buildings where people sleep. Carbon monoxide (CO) is a deadly, colorless, odorless, poisonous gas. It is produced by the incomplete burning of various fuels. Carbon monoxide poisoning can mimic flu symptoms such as headaches, dizziness, nausea and fatigue. Higher levels of exposure result in disorientation, drowsiness, unconsciousness and death.
Common sources of carbon monoxide include heating appliances, water heaters, clothes dryers, emergency generators, temporary cooking appliances or space heaters and motor vehicles running in attached garages or adjacent to a building
