    They are not all propelled by Nitrogen. As I said, in the ones we did the gas used was CO2.
    For every link you produce saying it's Nitrogen, I could provide a link saying O2. But, I don't want to go down that road so let's just leave it.
    BTW, you have just joined the list of members that I choose to ignore.

    I bought a water-mist extinguisher for domestic use as it's suitable for all types of fire, even electrical fires, and unlike water, foam and dry powder, doesn't cause a mess!

    How does it work with electrical fires? I'd be a bit concerned using that type on one as electricity can flash across banks of mist. (Think of sky lightening across the clouds, which when all said and done, are banks of mist).

    Bit of a difference in lightning and mains voltage I would have thought but not heard of mist extinguishers
    Edit: Just looked them up and good to 1000volts

    I haven't tried ours yet, Conny, but I feel confident of using it on an electrical fire if need be.
    I think that because the droplets are so fine and dispersed, any electrical potential would be insufficient to keep jumping across from one to the other.
    Anyway, ours has a plastic handle and I wear rubber soled slippers, so I'll be OK! :LOL:
