Fire extinguishers have colour codes labelling the type of extinguisher they are. These are represented on a band at the top of the extinguisher. Their purpose is to make identification easier and faster for the user.
Each extinguishing medium is assigned its own colour code:
Red for water, cream for foam, blue for dry power, and black for carbon dioxide. A fifth colour, yellow, is added for the new Wet Chemical type of fire extinguisher.
