Carbon Monoxide – British Standard BS EN 50292:2013

What is the British Standard BS EN 50292:2013?

Carbon Monoxide is a silent killer, you can’t see it, smell it or taste it. This is why having Carbon Monoxide alarms installed throughout a property is so important. The British Standard BS EN 50292:2013 offers recommendations on the installation and maintenance of Carbon Monoxide alarms.


The standard states that a Carbon Monoxide alarm should be fitted in:

Rooms that have any fuel burning appliances – such as an open fire, gas cooker or boiler

Rooms where people spend the most time – such as a living room

Rooms where people sleep

Any room that has a flue running through it

This means that a Carbon Monoxide leak can be detected from all the potential sources and heard throughout the property.



If you have a limited number of alarms then you should look to cover the areas that are at highest risk including:

Rooms with a flueless or open-flued appliances such as an open fire, gas cooker or portable heater – these would leak carbon monoxide directly into the room producing the greatest risk

Rooms where the occupants spend the most time – this is to ensure that they are protected to any carbon monoxide exposure in these areas and also hear the alarm as soon as possible



What else should I consider?

You should look for a product that has been manufactured and approved (e.g. Kitemarked) to standards BS EN 50291-1:2010 (for domestic premises) and/or BS EN 50291-2:2010 (for caravans and boats). These standards show that the alarms have been extensively tested to ensure their quality including sensor reaction times, minimum alarm sound levels and temperature resistance.
