Carbon monoxide (CO) is a silent killer – it is colourless, odourless, and tasteless, making it extremely difficult to detect without the proper equipment. This is why having a carbon monoxide alarm in your home is crucial. But do you really need one, and which one is the best for your household?

In this blog post, we will explore the importance of having a CO alarm, who needs one, legal requirements, where to place your alarm, signs of carbon monoxide poisoning, what to do if your alarm goes off, and ultimately, help you find the best carbon monoxide alarm for your specific needs.

Why Have a CO Alarm?

You need a CO alarm to help protect your family from the dangers of carbon monoxide poisoning. It can be hard to detect without one since it’s an odourless and colourless gas. CO alarms are mandatory in rooms with fixed combustion appliances in privately rented properties, social housing, and when installing or replacing gas fires and wood-burning stoves. They’re also recommended for homes, caravans, motorhomes, boats, and camping.

Symptoms of CO poisoning vary, from cold- and flu-like symptoms to severe headaches, mental confusion, nausea, and fainting. If your alarm sounds, open your windows, evacuate the house, check for symptoms, and seek medical help if necessary. 

Stop using the gas fire or stove and switch off other fixed combustion appliances until declared safe by a professional. Ventilate the home and stay outside until the air is clear.

Who Needs One?

Everybody should consider investing in a CO detector if they have a gas boiler, fire or stove, as it’s mandatory in many circumstances. It’s also recommended for homes, caravans, motorhomes, boats, and camping.

Legal Requirements

As of October 2022, legally-mandated CO detectors are required when installing or replacing a gas fire or stove, as well as in privately rented properties and social housing.

It’s important to note that Carbon Monoxide is an odourless and colourless gas, undetectable without a detector. It’s also a good idea to have one in homes, caravans, motorhomes, boats, and camping, to ensure safety.

HETAS is an excellent resource for advice about CO in the home.

Where to Place your alarm

Positioning your CO detector correctly is essential for effective protection against carbon monoxide poisoning, so make sure it’s placed at least one meter away from fuel-burning appliances. Hang it at head height, around 5-6 feet above the floor or on the ceiling, in an area free from furniture, cupboards, ventilation equipment, and condensation.

Remember, the detector won’t be able to do its job properly if it’s not in the right spot. If your CO alarm sounds, quickly ventilate and evacuate the house and check everyone for symptoms. Don’t re-enter until the air is clear and you’ve had the gas boiler, fire or stove switched off by a professional.

We understand that protecting yourself and your family from the dangers of carbon monoxide poisoning is important. That’s why we recommend CO detectors for homes, caravans, motorhomes, boats, and camping. 

Signs of Carbon Monoxide Poisoning

If you’re exposed to carbon monoxide, it can cause symptoms ranging from mild flu-like symptoms to severe headaches, confusion, and nausea. Being aware of the signs of carbon monoxide poisoning is important, so you can take measures to protect yourself and your family.

Early symptoms of CO poisoning include headaches, nausea, dizziness, shortness of breath, fatigue, and confusion. If left untreated, these symptoms can become more severe, including chest pains, vomiting, loss of consciousness, and even death.

If you experience any of these symptoms, getting to fresh air immediately and seeking medical help is important. It’s also important to stop using gas appliances and have them inspected by a qualified professional.

Installing a CO alarm is the best way to detect the presence of CO in the home and keep your family safe.

What to do if your alarm goes off

If you suspect you’re suffering from the symptoms of carbon monoxide (CO) poisoning, it’s important to take the alarm seriously. Evacuate the house immediately and check for symptoms. Make sure everyone in the house is okay and seek medical help if needed.

Don’t forget to switch off all fixed combustion appliances like gas fires, stoves, or wood-burning stoves. Then, make sure your home is well-ventilated and stay outside until the air is clear. 

Remember, CO is an invisible, odourless gas and a detector is the only way to ensure your safety. Make sure you have the right one and it’s properly installed.
