Having each year during the SEP refresher seen the effectiveness of Halon I was disappointed when British Waterways removed Halon (BCF, bromodicholinefluridemethane??) from the waterways.
All our BCF's (having been replaced with dry powder) were then brought home where (illegally I am told) they sit in the kitchen etc as the very best extinguisher when (and if) that fire breaks out.
So far so good, no fires, no effect on the Ozone layer, but if.....
PS what about the channel tunnel, will they be replacing all their Halon extinguishers?
