Carbon Monoxide (CO) Alarms

Working smoke and carbon monoxide alarms are the most important device you can have in your home. They provide essential early warnings 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. The only way to tell that it is present is to have a working CO alarm.
