Apr 01, 2011 However many fire engineers do not use the current standard and the symbols below are used. Many of the following symbols are used by the British Fire Service and most probably based on BS 1635:1970. When marking up a drawing you could use any symbols of your own choice providing you create a legend showing what each symbol represents. You then combine a number of these elements into a symbol, for example the element for any type of extinguisher is a triangle, insert into the triangle the element for water, a circle with a vertical line and you have a Water Extinguisher. You can make them more complex and they are then called applications.
The list of abbreviations used in a set of architectural drawings varies from office to office. Be sure to check the front section of the drawing set for the abbreviations used within.
