Hi Brando,

Have a look at the free-to-download guide from the government. (Page 102)

Escape sign design:

For a sign to comply with safety signs and signals regulations it must be pictographic. The pictogram can be supplemented by text if this is considered necessary to make the sign easily understood (BS-type sign), but you must not have a safety sign that uses only text. Either type of sign can be used but different types should not be mixed. Appropriate signs should take into account the needs of those who may need to use them.
The legibility of escape signs is determined by the size of the sign, its level of illumination and the distance over which it is viewed. The use of signs within the same premises should follow a consistent design pattern or scheme. You should not rely on a few outsized signs which may encourage people to travel to a particular escape route when other more appropriate routes should be used.

In multi-occupied premises, co-operation between the respective ‘responsible persons’
should be sought to ensure that, as far as possible, all signs in the building conform to a single pattern or scheme. Signs should indicate non-automatic fire safety equipment if there is any doubt about its location, e.g. fire extinguishers that are kept in cabinets or in recesses. A notice with the words ‘Push bar to open’ should be permanently displayed immediately above the push-bar on all doors fitted with a panic bolt or panic latch. A notice with the words ‘Fire escape – keep clear’ should be permanently displayed at about eye level on the external face of all doors which are provided as a means of escape in case of fire and which, because they are not normally used, may become obstructed.

Hope that helps.
