Introduction
The current standard is BS 1635 : 1990 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.
Note. The symbols taken from ISO 6790 without modification are noted with
an asterisk.
