This British Standard gives recommendations and guidance for the design, specification, maintenanceand operation of permanently installed sound systems used for emergency purposes at sportsgrounds, venues and other large buildings/sites that have similar electroacoustic systems, occupancyand occupant-generated sound levels, to convey specific instructions to the public to manage theirbehaviour in a variety of situations.

The standard is applicable to emergencies that require full or partial evacuation and those for whichthere is a need to keep people inside a building, safe from danger outside.

Emergency sound systems in large public buildings, venues and sports grounds are covered bythis British Standard as a specific case because these form a class of building or complex which hascertain parameters which define a particular need in terms of life safety.
