Bloggs, what is the color of your extinguisher? Yellow (a la BCF/carcinogenic/banned) or Red (a la Halon (the non-carcinogenic/approved) one?
I am not certain of the type of halon in our extinguishers, except that it is "approved". What I am certain about (i.e. not befuddled) is that somewhere in the late '90s, the yellow BCF was banned (possibly with the exception of Oz).
