Merely there'due south another gas that is possibly even more than deadly because you lot can't come across it, scent it or taste it.

How to choose the all-time carbon monoxide alarm for you lot
What is carbon monoxide poisoning?
Carbon monoxide is known as the silent killer considering you tin can't smell it, taste it or come across it. Once it enters your bloodstream, it invades the red blood cells (haemoglobin), preventing them from carrying oxygen effectually the torso. Symptoms of carbon monoxide poisoning include a influenza-similar headache, dizziness and nausea followed by tiredness, confusion, breathlessness, weakness, loss of muscular coordination and – cartel I mention information technology – decease. CO is and so odourless that even dogs can't detect it.
How exercise CO alarms piece of work?
The wellness effects of CO depend on the concentration and length of exposure (carbon monoxide concentration is measured in parts per meg). According to respected CO alarm manufacturer Kidde, "a carbon monoxide detector is a time-weighted alarm that measures the buildup of carbon monoxide in a business firm.
"For a person to begin feeling the effects of carbon monoxide poisoning, they would demand to be exposed to a carbon monoxide level of 50 parts per million (ppm) for eight hours. An alert's response fourth dimension volition vary depending on the level of carbon monoxide in the air. For example, an alarm will sound after three and a half hours of continuous exposure at a level of 50ppm, nevertheless volition sound afterward eight minutes of continuous exposure at a level of 400ppm."
Carbon monoxide sensors accept a finite lifespan of between five and seven years, although a few manufacturers now claim that their sensors will last a full ten years. Mostly speaking, it's worth playing information technology safe and replacing your warning a twelvemonth or two before its life is supposed to run out. Tests in the US take shown that alarms over eight years old tin fail to detect CO at levels of higher up 400ppm.
It's also worth noting that the test push button on these devices doesn't actually test the sensor – it only makes sure that the circuit's working.

What levels of CO are considered dangerous?
Most people will not feel whatsoever symptoms from prolonged exposure to CO levels of under, say, 40ppm. It depends on the length of exposure, but the real danger level starts at around 400ppm (two to three hours of exposure at this level can be life-threatening). To requite you some idea of how dangerous higher levels of concentration tin exist, 1,500ppm could result in expiry inside an hour and vi,000ppm within 15 minutes.
All of these concentrations are bad enough when you're awake and realise that something isn't quite right – especially if others are feeling a similar event – but if you lot're asleep, you may wake upwardly with a severe headache and nausea and be incapable of even crawling for fresh air. Worse, yous might not even wake up at all.
Why should I be concerned?
According to the NHS, 25 people die every year in the United kingdom of great britain and northern ireland from accidental CO poisoning. For actress peace of mind, you're advised to have your boiler, gas burn or wood/coal fire'due south flue checked at regular intervals. And never utilise a gas-powered lamp or cooker inside a tent.
Where should I install my CO alarm?
Most manufacturers propose locating your alarm side by side to or most a gas appliance, and it's worth having ane in the same room as whatever burn down or woods-called-for stove. It should be around 1.5m from the ground and at least 30cm abroad from any ceiling, and most tin be mounted on a worktop, shelf or table – or merely mounted on the wall.
Don't think that CO alarms are only for your habitation, either. They're essential for caravans and motorhomes, and yous might even want to accept one on vacation if you're staying in a cottage or self-catering accommodation.
Are there any features worth looking out for?
Mostly speaking, CO alarms are pretty basic devices. Only the new and more expensive smart or app-continued alarms have any real features to speak of. The most important thing to look for is British Standards certification. CO alarms should exist kitemarked to EN50291-1:2018 for use in domestic premises, and BS EN 50291-2:2010 for use in the dwelling or a boat or caravan. The second standard more often than not ensures that the alert is tough plenty for use on the move.
Otherwise, the key features come down to whether in that location's a brandish and how the alarm is powered. A growing number of CO alarms now have a display which gives yous the sensor's current reading on CO particulates in the air, though – to save batteries – you'll but see this afterward a exam or if the reading goes to a higher place safety levels.
Until recently most CO alarms ran from a set of removable AA or AAA batteries, which may need to be replaced every three to five years. Nonetheless, many now employ a sealed-in Lithium bombardment designed to last for the same lifespan every bit the sensor; y'all buy the unit and just replace information technology when the lifespan's upwardly. This is arguably safer, and a new Scottish police force volition crave from 2022 that homeowners and landlords either fit tamper proof alarms with a long-life Lithium battery or a mains-wired CO alarm if there's a carbon-fuelled apparatus – like a boiler, woodburner or open up fire – on the property.
