Graphical Symbols and Abbreviations for Fire Protection Drawings

Architects have their own abbreviations, symbols and drawing conventions to enable all persons in their profession to understand drawings produced for their use. Drawing Conventions are subject to BS 1192 : 2007 Collaborative production of architectural, engineering and construction information. Clicking on the above link will provide you with some information on this standard. I am not sure if British Standards Institute has produced Standards to cover all the professions however there is a British Standard to cover Fire Engineering. The current standard is BS 1635:1990 “Recommendations for graphic symbols and abbreviations for fire protection drawings” and clicking on this link will provide you with some information on this standard. 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. Depending on the reason for the drawing, Means of Escape for instance you may use the symbol to show an area to be covered , in accordance with the current British Standard, not the exact location and the symbols below would be acceptable. Other times an emergency lighting engineer for instance would require to show the exact location of a luminaire to enable the electrician to fit it, in accordance with the current British Standard. In this situation BS 1635 : 1990 would be more useful for the purpose.

AutoCad Fire Symbol Block Library

If you have AutoCad you could download a symbol block library for Fire Certificate Symbols (older standard). You may have to scale them up or amend them. The font used for the symbols was Bold Courier New 100 mm (0.1) and the descriptions are Txt 70mm.(0.07)

You could also try this interpretation of a few of the BSI Current Symbols you may find them useful. Because of the large number of permutations, I have only include the ones that I feel are best suited to Fire Safety and not fire engineering (mechanical or electrical) drawings. On your legend you could use the term ” Area covered in accordance with the current British Standard ” when you cannot identify an exact location.The font used for the symbols was Bold Courier New 200 mm (0.2) and the descriptions are Txt 100mm.(0.1).

The Autocad symbol libraries can downloaded below:

Fire Symbols (Both Libraries) –  Download
Fire Certificate Symbols (older standard) – Download
BSI Current Symbols – Download

I would appreciate any feedback from anybody who is competent with AutoCad and has downloaded the symbols. I would like to know if they are functional and do they work, this will enable me to improve the block libraries.
