Emergency lighting design can be a can of worms especially when you consider that there are differences between the European specs and BS, they have actually made allowances for us

Hopefully, if I work things right there should be a list next of all the regulations etc which have a bearing on the subject:-
Primary UK Legislation 1.The Fire Precautions in the Workplace Act 1997 – Further guidance is available in the HSE book “Fire Safety – an employers guide” 2.Health and Safety at Work Act 1974 3.The Workplace (Health, Safety and Welfare) Regulations 1992 4.Building Regulations Act 200 – Document B 5.The Cinematograph Act 1952 6.Health and Safety (Safety Signs and Signals) Regulations Act 1996 Other legislation dealing with premises licensed or registered for public assembly or residential purposes. e.g. Licensing Act, Local Government Miscellaneous Provisions Act, Theatres Act, Residential Homes Act etc. the guides for which all contain a requirement for emergency lighting. Standards and Codes of Practice BS 5266 Pt 1 1999 code of practice for the emergency lighting of premises other than cinemas and certain other specified premises used for entertainment. CP1007 1955 Maintained lighting for cinemas BS EN 60598-2-22 1999 specification for luminaires for emergency lighting BS 5499 Pt 1 1990 specification for safety signs including fire safety signs BS 5499 Pt 2 1990 Specification for self-luminous fire safety signs BS 5499 Pt 3 1990 Specification for internally illuminated fire safety signs If anybody is interested I can email a seventeen page emergency lighting design guide to them
