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. The current fire protection drawings standard is BS 1635: 1990 Recommendations for graphic symbols and abbreviations for fire protection drawings . 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 can use 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.
