Emergency Lighting

Emergency Lighting: For Industrial, Commercial and Residential Premises concerns itself with the provision of emergency lighting to facilitate exit routes for people in industrial, commercial, and residential areas. The book covers important topics such as the objectives of emergency lighting systems; the identification of safe routes under low lighting in different areas; and related devices such as luminaires, emergency signs, and way-guidance. Also discussed are the applications of emergency lighting; factors to consider in the design of emergency lighting; electrical installations; and testing and servicing. The book has appendices that serve as guides to UK emergency lighting equipment, names to be contacted, and a short guide in case of fire. The text is recommended for building planners, engineers, and architects. The book is also applicable to those who would like to know about emergency lighting but do not have any specialist knowledge on the subject, as the book avoids the use of jargon.
