CO Gas Detectors

[mmitchell]

dose any one know if you can by CO Gas Detectors, that pick up the smell of gas, only my son says he can smell gas in his bedroom from time to time.

we have some one out to try to find the smell, but with no luck

Carbon Monoxide has no smell, if he can smell gas it's the gas that's coming in through your gas main.

Before I start, a disclaimer, as I have no specific knowledge on this subject, but I do have some knowledge on related subjects which I think are relevant. But of course on something that relates to safety, you must be certain of your source of information.

 

Firstly, I doubt that a CO monitor would register natural gas, as there isn’t any (or only a trace of) CO in natural gas. However, I don’t know how specific the sensors are – maybe there is something in Nat Gas that will set off a CO sensor.

 

Secondly, the whole point of the smell in gas is that it warns you of the gas even at very low levels of the gas, well below danger levels. It is therefore likely that you can smell gas long before it becomes a danger, and therefore probably before a sensor would be set off – nobody wants a sensor to alarm at very low levels as you would get false alarms. I would guess that your son’s sense of smell is likely to be better than a detector. However, lots of things can give off smells, which can build up in an enclosed space, which may then remind him of gas – some soft plastic toys such as beach balls, for example. Could it be something like this, with the smell being quickly dispersed when the door is opened and people walk about?

Thanks for the advice Easter sundae, it's only his bedroom what's got the smell now and then, after the door has been closed for some time.

What we will have to do is clear some things out of the room to find out if it's any of his stuff

A monoxide detector will not detect natural gas. What will find natural gas is a smoke detector that works on the hot wire principle, (ones that work on ionisation won't help). You can get this sort of thing modified to act as a combustible gas detector, but they are pricey.

Are there any gas pipes close to the room? eg under the floor or through a cupboard. Is there any route that gas could get into the room if it were leaking from somewhere else - remembering that gas is lighter than air, so would rise to where it can be smelled? If so, try smelling in these areas, to see if it is stronger there.
