Carbon Monoxide – Are you covered?

10 September 2018

Carbon Monoxide (CO) is otherwise known as the silent killer. This is because it is a gas that you cannot see, smell or taste. So this begs the question, how do you know if you have a CO leak?


Finding a CO leak

Due CO being almost impossible to spot, the only way to tell that you have a CO leak is by having a working CO Alarm fitted. Carbon Monoxide standards are taken from BS EN 50292:2002, within which it states that ideally, an alarm should be installed in every room containing a fuel-burning appliance and additional alarms should be installed to ensure that adequate warning is given for occupant in other rooms.

As the image below shows, you should:

  • Locate an alarm on the ceiling where the the appliance is in the room, as seen in the kitchen.
  • Site an alarm on the wall, at breathing height, in a bedroom where an enclosed flue runs through the room. You site this on the wall because the alarm needs to wake you when CO is at breathing height, which would be bedhead height whilst asleep.
  • Site an alarm in the living room as it has a fire place, as well as the rooms above that the flue will run through.


A common misconception of CO regards how heavy it is, it has the same density as air so in the room with the appliance the CO alarm would need to be sited on the ceiling 1-3 meters from the appliance to allow for best protection.



What are the symptoms of CO poisoning?

Many people do not know the symptoms of CO as they are similar to flu, this leads to 4,000 people a year going to A&E with CO poisoning!*

Would you know if you had background CO levels?


It is possible to have some background CO in your home without it being enough to trigger an alarm. The best way to find this out is to do an AuidioLINK Data Extraction report from any Aico CO Alarm via the AudioLINK App on your smartphone. AudioLINK can also tell you things such as the sensor status and battery life, to find out more, visit our AudioLINK page.
