BS 5499 covers all safety warning sign, including fire safety signs and is compatable with the Health and Safety (Safety Signs and Signals) Regulations 1996. It is also compatable with the ISO standards relevant to fire signs but in regards to EC Safety Signs Directive 92/58/EEC – fire exit signs there is some confusion. Some manufacturers interpretation of the directive and the Safety Signs and Signal regulations and produced an exit sign (Euro sign) which is in conflict with BS 5499. This is very likely to be rectified shortly and Europe will fall in line with BS 5499 and the ISO. There are many warning signs but I will concentrate on the fire warning signs.

These signs prohibit actions detrimental to safety

Signs that require actions or activities that will contribute towards safety
|White graphical symbol on a blue circle. Because the “Fire Door keep shut” sign doesn’t have a pictogram it is not in accordance with EC directive|
These signs give warning of potential risks
|Black graphical symbol on a yellow triangle that has a strong black border.|
|Safe Condition Signs
These signs indicate exit routes in the event of a fire or emergency
|These signs indicate exit routes in the event of a fire or emergency|
|Fire Equipment Signs
These signs are used to indicate the location of fire equipment
|White graphical symbol on a red square.|
|Supplementary Information Signs||Determined by the appropriate sign.|
BS 5499 Part 4
BS 5499 part 4 is devoted to escape route signing and while good sign design practice is important, the correct application and positioning of those signs is of equal significance in ensuring an effective signing system is in place. The size and positioning of signs within a building should form a major part of the package. It clearly and concisely deals with all aspects of the design of an effective escape route signing system.
Points to consider are
- Sign type, sign size and viewing distance
- Construction durability and suitability
- Servicing and maintenance
- Illustrations (use of safety signs)
- Use of arrows to indicate direction of travel
It also deals with the issues associated with designing a coordinated system of signing throughout any given building. The code outlines items that need to be addressed in considering the overall design, including,
- Results of any risk assessment
- Requirements (if any) of enforcing authorities
- Operational needs of the building’s managers
- Convenience of the users of the building, both workers and Public
The code stresses that it is only through the consideration of these factors that an effective design system for escape route signing can be achieved. It provides clear guidance on how to do this.
Examples of BS 5499 Escape route signing
|Supplementary directional arrow.||The internationally recognised graphical symbol for emergency exits||Supplementary text|
Exhaustive testing both comprehension and judgment testing of graphical symbols conforming to BS5499 and ISO 7010, ISO16069 achieved the highest comprehension credentials. However as it only achieved some 80%, the British Standard requires supplementary text to aid comprehension. This too was tested and achieved 100% comprehension under ISO 9186. (Comprehension Testing Standard) Both International and British Standard Technical committee agreed that Escape Route Location and directional identification should not be left to graphic symbols alone. Consequently escape route signs should normally consist of three elements, the internationally-recognised graphical symbol for emergency exits, supplementary text (Exit or Fire exit) and a directional arrow.
The British Standard should be available from your local reference library.
