Fire Extinguisher Colours as Well as Their Definition

Various fire extinguisher colour codes are employed between Europe, Australia and America. Also, there are variations within each location. For instance a number of the older extinguishers use different colour codes.

Colour coding evolved in 1997 for The European Union as a result of the introduction of BS EN 3. Before BS EN 3 solid colours were utilised, but BS EN 3 introduced coloured bands instead.

Throughout Australia yellow halon fire extinguishers are against the law to possess or use. An exception to this is if a necessary use exemption has been granted.
There is not any formal standard in the States for fire extinguisher colours.

Nevertheless, they commonly use colour coded geometric shapes and pictograms depicting the types of fires which the extinguisher is approved to combat.

Given all the variants in fire extinguisher colours, what follows is easily the most common convention for today's fire extinguisher colours/pictograms in each geographical area.

When deciding on the proper fire extinguisher to use for any given situation the colour coding is made to make the different types of extinguisher simple to identify.

It's really a shame there isn't an international standard for extinguisher colour coding but like most things, it is difficult to keep consistency across the world. This is mainly as a consequence of historical reasons.

Nonetheless, the colour coding shown above is a good guide and there are similarities between the various countries and continents so that it is easier to understand them.
