This standard describes the planning, design as well as setting principles and requirements of a safety way guidance system (SWGS) in public building.
This standard is not only applicable to design and arrangement of electric light source element and phosphorescent light element of SWGS in public building but also applicable to the situation that different SWGS elements are determined according to SWGS service environment, materials, design, installation and maintenance.
This standard also does not include the special considerations of possible tactile or audible emergency facilities of SWGS, nor does it include requirements concerning the emergency escape route lighting, especially the design and application of emergency escape route lighting, unless illumination is used to mark safety equipment or special features of the escape route like the emergency exit doors or stairs.
This standard is not applicable to SWGS design and arrangement of ships through waterway and sea transportation.
