1 Scope

1.1 This Standard covers the principles governing the design and application of visual components used to create a safety way guidance system (SWGS) and requirements for the installation, inspection, testing and maintenance of SWGS.

1.2 This Standard contains general principles valid both for electrically powered and for photoluminescent components. Special information which is related to the type of component is given to assist in defining the environment of use, choice of material, layout, installation and maintenance of SWGS.

NOTE: This Standard recognizes that a safety way guidance systems may have additional features or functions differing from those detailed in these requirements, if the features or functions enhance the life safety of the occupants of the building.

1.3 This Standard does not provide guidance for egress safety evaluations. Applications with different risks to the occupants typically require different layouts and types of SWGS. SWGS is to be reviewed by qualified persons.

1.4 This Standard also does not include the special considerations of possible tactile or audible components of SWGS, nor does it include requirements for high mounted components of the emergency egress / emergency means of egress lighting, especially the design and application of emergency egress / emergency means of egress lighting.

1.5 The installation of components not covered by these requirements shall be in accordance with good engineering practice and manufacturer's published installation instructions.
