How do carbon monoxide detectors work?/A carbon monoxide detector or CO detector is a device that detects the presence of carbon monoxide (CO) gas to prevent carbon monoxide poisoning. In the late 1990s, Underwriters Laboratories changed the definition of a single station CO detector with a sound device to carbon monoxide (CO) alarm. This applies to all CO safety alarms that meet UL 2034 standard however for passive indicators and system devices that meet UL 2075, UL refers to these as carbon monoxide detectors.
The worrying trend was also witnessed in other parts of the globe, and this has led to governments and other organizations encouraging people to install detectors and alarms to stop death. In fact, Forbes, in an earlier article has also described carbon monoxide as “A Silent Killer”

The Installation Of Carbon Monoxide
It’s important that you have installed the detector properly. Failure to do so may affect the functionality and precision of the unit. If you aren’t very conversant with the device or aren’t confident about the installation, you should seek help from an expert. The below YouTube video should help you with the installation.
How do carbon monoxide detectors work?
Carbon monoxide detectors sound an alarm when they sense a certain amount of carbon monoxide in the air over time. Different sensors set off different types of alerts.
- Biomimetic sensor – a gel changes color when it absorbs carbon monoxide, and this color change triggers the alarm.
- Metal oxide semiconductor – When the silica chip’s circuitry detects carbon monoxide, it lowers the electrical resistance, and this change triggers the alarm.
- Electrochemical sensor – Electrodes immersed in a chemical solution sense changes in electrical currents when they come into contact with carbon monoxide, and this change triggers the alarm.
Once the alarm sounds, the carbon monoxide detector must be in a carbon monoxide-free environment to reset itself.
10 Steps to Prevent CO Poisoning
OSHA and the CDC say that CO poisoning can be prevented if you follow these steps:
- Install battery-powered CO detectors on every floor of your home.
- Change the batteries every 6 months.
- Schedule a qualified technician to annually service your heating system, water heater, and any other gas, oil, or coal-burning home devices.
- Keep air vents and flues free of debris that can block ventilation lines.
- Never run a generator, or any gasoline-powered engine inside your home, garage or basement, even if the windows and doors are open.
- Never run a generator, motor vehicle, pressure washer, or any gasoline-powered engine, even if outdoors, if it’s less than 20 feet from an open window, door, or vent. Exhaust can enter into your home.
- Never use an oil lantern, charcoal grill, hibachi, or portable camping stove inside your home, camper or tent.
- Use tools and heating appliances powered by electricity or compressed air instead.
- Never leave your vehicle’s motor running in the garage or any partially enclosed space.
- If you suspect CO poisoning, call 911 and go outside for fresh air while you wait.
How can I prevent carbon monoxide poisoning?
Carbon monoxide poisoning is a serious risk, but fortunately, it’s very preventable. In addition to installing sensors throughout your home, here are a few tips for avoiding a dangerous situation.
- Never heat your home with a gas range – Gas stoves produce carbon monoxide and can fill your home with the dangerous gas.
- Don’t run your car in the garage – If you want to warm up your vehicle in the winter, pull out of the garage first. Carbon monoxide is a common byproduct of vehicle exhaust, and it can build up quickly in a closed (and open) garage.
- Always have proper ventilation – Running your generator, pressure washer, or any gas-powered engines in an enclosed area like a basement or garage without adequate ventilation can be extremely dangerous.
- Always cook safely while camping – You should enjoy the wilderness safely. Don’t use a charcoal grill, hibachi, or camping stove inside your home, tent, or camper.
- Install a carbon monoxide detector – The best carbon monoxide detectors are affordable, easy to install, and can save your life. We recommend installing one on every level of your home, near each bedroom, and near your garage
Final Word
After looking at the above statistics and learning about carbon monoxide, you are certainly worried if you haven’t installed a CO detector. As you have seen, the cases of deaths have risen globally. This may be attributed to rising use of heating devices and fuels that emit poisonous gas. The most worrying thing is that the gas is odorless, tasteless, and colorless. You may even be inhaling it now as we speak.
The good news though, is that you, your family and other people in your home or even office can stay safe. You only need to install the right CO detector to alert you of any presence of the gas. We have picked the best carbon monoxide detectors and alarms in 2019 that guarantees you the best service and improved safety.
