Show Editor’s Note: This blog post was originally published in October 2018 and has been revised to reflect industry updates. Installing a carbon monoxide (CO) detector in residential and commercial buildings is extremely important, as it indicates the presence of this odorless, colorless, tasteless, and potentially fatal gas. An effective detector will sound a beeping or chirping noise to warn those inside to quickly leave the premises. According to the most recent 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 agency adds that of those, more than 430 will lose their lives. To ensure a properly functioning CO detector, homeowners and business owners must periodically perform tests and inspections. The first indication of a potential issue is a beep or chirp—occurring anywhere between every 30 seconds to five minutes. This could be one of two things. Below we’ll discuss how carbon monoxide detectors can protect your loved ones and property, and why it’s important to conduct regular device inspections, testing, and maintenance.
How Do CO Detectors Work?Powered by batteries or connected directly to residential and commercial electrical systems, CO detectors function via a silicon microchip, sensors, and semiconductors. Upon detecting this potentially fatal gas, they sound a beeping or chirping noise indicating potential danger. Detectors equipped with LCD screens also display CO levels and system statuses to indicate inspection deadlines. CO detectors also signal noxious gas buildup, even before occupants experience symptoms. For example, low CO levels of approximately 50 parts per million (ppm) won’t trigger beeping for several hours, while 150 ppm sound detectors almost immediately. CO Detector Beeping & Chirping SignalsIt’s important to reiterate: Carbon monoxide can be fatal. Because CO detectors protect people from this dangerous gas, incessant chirping should signal occupants to immediately leave the residence or place of business. This deadly gas may be present, and fire emergency professionals should be contacted, immediately. When listening for CO detector beeps or chirps, there are differences between patterns. Note the following:
CO Poisoning Symptoms & ExposureAccording 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:
The American Association of Poison Control Centers is also available for medical advice on this and other potentially fatal situations.
