Yes, quite correct Danny Boy, the UK is similar. I did not bother posting about it before, as there are always people that know it better. I have lost count of the number of fire fighting courses that I have attended, and have the log books to prove it!

Colour coding of Extinguishers
The type of extinguisher is identified by a colour coding as indicated below. The old fire extinguishers standard required the whole of the body of the extinguisher to be painted the appropriate colour. You will find these extinguishers in many premises and these are still legal, you do not need to change them unless the extinguisher is defective and needs to be replaced. New extinguishers are manufactured to the standard BS EN 3.
Water extinguishers are coloured signal red.
Other extinguishers will be predominantly signal red with a label, band or circle covering at least 5% of the surface area of the extinguisher in a second colour indicating the contents of the extinguisher.
Fire extinguishers colour-coded green are vapourising liquids (Halons) and have been illegal, with some exceptions like aircraft and the military, since the end of 2003 as the result of the Montreal protocol. They need to be disposed of legally, for more information go to Phasing out Halons in portable fire extinguishers.
