Carbon Monoxide Alarm | Brief

Carbon Monoxide Alarm are as important as your Fire Alarm, shockingly enough more than two thirds home in The UK doesn’t have Carbon Monoxide Alarm installed. Our Team of expert installers and Emergency electricians have put together this blog. Before we talk about what a Carbon Monoxide Alarm is let’s just brush up on What Carbon Monoxide is, in case this may bring your favourite chemistry teacher’s chemical bonding doodle drawing you may skip this part.

What is Carbon Monoxide, AKA (CO)?

As per Wiki “Carbon monoxide (CO) is a colourless, odourless, and tasteless gas that is slightly less dense than air.

It is toxic to hemoglobic animals (both invertebrate and vertebrate, including humans) when encountered in concentrations above about 35 ppm, although it is also produced in normal animal metabolism in low quantities, and is thought to have some normal biological functions.

In the atmosphere, it is spatially variable and short lived, having a role in the formation of ground-level ozone.”

Carbon Monoxide Alarm | The risks

You cannot see it, taste it or smell it but CO can kill quickly with little warning. Around 50 people die every year from CO poisoning caused by gas, oil and solid fuel appliances and flues that have not been properly installed, Maintained by or that are poorly ventilated. Lower CO levels that do not kill immediately can cause serious harm to health if breathed in over a long period. In extreme cases paralysis and brain damage can be caused as a result of prolonged exposure to CO. Increasing public understanding of the risks of CO poisoning and taking sensible precautions could dramatically reduce this risk.


The HSE strongly recommends the use of audible carbon monoxide (CO) alarms as an important precaution but they must not be regarded as a substitute for proper installation and maintenance of gas appliances by a Gas Safe Registered engineer.
