What Is A Carbon Monoxide Detector And How Do You Choose One?

Carbon monoxide (CO) is an odourless, colourless, and tasteless toxic gas. It is a product of incomplete combustion and can be omitted from almost anything you can burn. Sadly, in 2020, it took 116 lives in the UK.

 A carbon monoxide detector is a simple way to protect yourself against this toxic gas. Here’s a buyer’s guide to help you choose the best carbon monoxide detector in the UK, helping you defend your home and loved ones.

What Does A Carbon Monoxide Detector Do?

A carbon monoxide detector identifies when CO has reached a dangerous level in a particular area, sounding an alarm to alert nearby people. On hearing this warning, they are able to evacuate to a safe space before inhaling too much toxic gas.

How Do They Work?

Your detector’s functionality depends on the type of carbon monoxide monitor you have bought. Three main variations are available that all use different methods of detection.

1. Biomimetic Sensor

These sensors contain a gel that changes colour when it absorbs carbon monoxide. A sensor identifies this change and signals the processor to trigger the alarm. Then the detector should be placed in a CO-free zone to reset itself.

2. Metal Oxide Semiconductor

This detector monitors the resistance in an electrical circuit within the device. When CO is present, the resistance decreases. The processor picks up this drop and triggers the alarm.

3. Electrochemical Sensor

These sensors also detect a change in electrical current. They have electrodes submerged in an electrolyte solution that generates an electrical current when CO is present. 

Choosing A Detector

On 27th September 2022, British Standards introduced a new verification for carbon monoxide monitors, standard EN 50291-1:2018. Look out for this certification when buying a new detector.

Another factor to consider is how you’d prefer your monitor to run. It’s possible to buy variations powered by replaceable batteries, sealed 10-year lifespan lithium batteries or mains AC power. 

Similarly, devices can be standalone or interlinked. An interlinked system will cover the entire house and alert everyone to high CO levels in one area. Some of these models can be connected to a home security system and send alerts to your phone. Whereas, standalone units only operate in their location but are still the most popular and affordable option.

Implementing carbon monoxide and smoke detectors in your fire alert system increases its effectiveness. You can also buy a combined smoke and carbon monoxide detector to identify any gases produced by a fire. These devices provide further coverage in an emergency.

Buyer Tips 

When it comes to weighing up your options, bear in mind our top tips for buyers:

• Choose A Reputable Brand – A brand with a history and good reputation will produce reliable devices
• Buy An Audible Alarm – Some detectors have colour indicators that have to be checked constantly and could be forgotten. An audible alarm omits a more obvious alert
• Consider A Portable Carbon Monoxide Detector – A portable device can be used anywhere, and you can take it with you if you travel to ensure extra safety
• Buy Quality – Take your safety seriously, and don’t look for a bargain. Buy the best quality you can afford

Detector Maintenance

You can take a few simple steps to maintain your device and extend its life span:

• Test the alarm once a week. Most models have a button to test them easily.
• Replace the batteries once a year.
• Listen out for unprovoked beeps, as they could indicate faults, low battery levels or end-of-life. 
• Keep track of your device’s lifespan; most last between five and seven years, but always check your specific model. If your alarm meets the recent British Standard, it will have an end-of-life indicator. 

Sources Of Carbon Monoxide

Any combustion can emit carbon monoxide, no matter what the fuel is. Common household sources include fuel burners like heaters or fireplaces, tools such as generators and kitchen appliances. 

Risks To People 

Without proper ventilation, CO can reach deadly levels. Carbon monoxide poisoning occurs when the gas enters your bloodstream. Your heart unknowingly pumps this poison around your body, damaging your organs in the process. In large enough doses, this poisoning can be fatal.

It is particularly dangerous to young children, the elderly and anyone with existing breathing difficulties or circulatory issues.

Poisoning symptoms include:

• Nausea
• Vomiting
• Dizziness
• Burning Eyes
• Headaches
• Breathing trouble 
• Chest Pain
• Confusion
• Fatigue

If you think someone is suffering the effects of CO poisoning, ring 999 for an ambulance immediately. 

How To Prevent Carbon Monoxide Poisoning

There are a number of precautions you can take to reduce the chance of carbon monoxide leaking into your home or place of work.

• Never heat your home with a gas stove– they produce CO so this action would fill your house with gas
• Don’t run your car in enclosed spaces– CO is found in exhaust fumes and will build up in enclosed areas like garages
• Practice safe cooking– cooking, especially barbequing, can produce CO. Ventilate your cooking area properly to remove toxic gases
• Service heaters and chimneys – combustion devices should be serviced regularly by professionals to ensure they work safely
• Install a carbon monoxide detector – an affordable detector is the easiest way to avoid poisoning as it alerts you when dangerous levels of CO are present

FAQ

Where should I put carbon monoxide detectors in my home?

You should put detectors on each floor of your home, next to bedrooms and by doors that lead to garages. 

How many detectors should I install in my home?

It is recommended that you install a carbon monoxide detector on each floor of your home, and in some circumstances, like rented properties, this recommendation is enforced by UK law. You can have more devices for added protection.

What should I do if the Carbon monoxide alarm triggers?

1. Move to fresh air, most likely by leaving the building, and open doors and windows when possible to ventilate. 
2. Check any inhabitants for flu-like symptoms of carbon monoxide poisoning. If these symptoms are present, call 999. 
3. Do not reenter your home until the alarm has stopped or the emergency services have deemed it safe. 
4. Contact a qualified professional to assess appliances that could release CO.
