Installing a carbon monoxide (CO) detector in commercial and residential buildings is extremely important, as it indicates the presence of the odorless, colorless, tasteless, and fatal gas. An effective detector will sound an alarm or siren alerting those inside and warning them to quickly leave the premises.

According to March 2020 statistics from the Centers for Disease Control and Prevention (CDC):Approximately 50,000 people in the U.S. visit the emergency department each year due to accidental CO poisoning.”

The CDC adds that of these instances, more than 430 will be fatal.

To ensure a CO detector works, consumers and business owners must remember to have the device inspected periodically. The first indication of a potential issue is a beep occurring about every 30 seconds.

This could be one of two things.

A beeping CO detector could signify gas presence, or a low battery. Whether the former or latter, the device itself should be replaced.

According to March 2020 statistics from the Centers for Disease Control and Prevention (CDC): “Approximately 50,000 people in the U.S. visit the emergency department each year due to accidental CO poisoning.”


CO Detector Chirping

As aforementioned, carbon monoxide could be fatal. CO detectors are meant to protect people from this dangerous gas. Incessant chirping should encourage occupants to leave the residence immediately—because carbon monoxide may be present—and contact fire emergency professionals who can assess the property.

According to the New York State Department of Health: "If you suspect CO poisoning, have everyone leave the area to get fresh air immediately. Contact the fire department and the gas company or heating contractor.” 


The agency also recommends scheduling regular inspections of home heating sources, such as furnaces, fireplaces, and chimneys.

Watch for the following symptoms if you think you may have been exposed to CO:

  • Nausea 
  • Chest Pain
  • Dizziness  
  • Shortness of Breath

The national health organization American Association of Poison Control Centers is also available for medical advice on this, and other potentially fatal incidences. 

Batteries & Replacement

Although some CO detectors have replaceable batteries, units with 10-year sealed lithium batteries will also beep due to an end-of-life warning. 

It’s important to keep track of a CO detector’s age and conduct regular testing, inspections, and maintenance.
