Graphical Symbols and Abbreviations Standard BS 1635:1990

Introduction

The current standard is BS 1635 : 1990 and has been produced with the agreement of the Fire Standards Policy Committee and replaces BS 1635: 1970. During preparation the international standard ISO 6790 “Graphical symbols for fire protection plans”, was considered and those symbols have been used wherever possible, with consideration of the content of BS 1635 : 1970. The format uses the style as recommended in BS 1192 Part 3: 1987 and ISO 6790, and incorporates precedents that exist in best British drawing practice. The names given to symbols have wherever possible been derived from BS 4422 and the wording used in group 9, Fire safety signs, complies with BS 5499: Part 1. BS 1635:1990

The rationale they have used, is to produce simple icons that representing one piece of fire engineering and are called element. 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 symbol for a hose reel is a semicircle, with the water element inserted, add an outlet which is an arrow, and the element for length of hose in meters and you have an application.

The application for a hose reel shows the length of the hose in metres in the upper right hand corner and although contrary to the standard I believe it should be also apply to portable extinguishers.

The above is only a very brief introduction and the symbols are simple sketches produced by me consequently you need to research the British Standard by purchasing a copy or use the local reference library who may have copies.
