Abstract

On a multiple building site, emergency evacuation procedures can lead to dangerous situations in which people are exposed to possible harm when one or more buildings are evacuated in the wrong direction(s) or the wrong exits are used. Certain emergency situations do not call for building evacuations, but movement to interior rooms and corridors. Visitors or persons new to a building are not usually familiar with a building's floorplan and exit routes. Methods of emergency announcement over intercom systems, which are intended to cover a campus of buildings, are not sufficient for many situations.

Emergency and Location Dependent Evacuation and Relocation Notification

      On a multiple building site, emergency evacuation procedures
can lead to dangerous situations in which people are exposed to
possible harm when one or more buildings are evacuated in the wrong
direction(s) or the wrong exits are used.  Certain emergency
situations do not call for building evacuations, but movement to
interior rooms and corridors.  Visitors or persons new to a building
are not usually familiar with a building's floorplan and exit routes.
Methods of emergency announcement over intercom systems, which are
intended to cover a campus of buildings, are not sufficient for many
situations.

      Today's technology has produced many methods of providing
relocation instructions, using both sound and sight, to building
occupants during an emergency.  One familiar method is the use of
intercom systems (i.e., loudspeakers) to produce both siren like
sounds and to relay voice messages to building occupants.  A newer
and mostly unfamiliar method employs light filaments arranged in the
shape of easily recognizable arrows and placed within a porous
surface, such as carpeting or ceiling tile.  These light filaments
are undetectable when not activated.  When activated, they produce a
very obvious indication of intended movement for the occupants of a
building.

      This invention involves the coordination and activation of
priority based, multiple emergency procedures between multiple
buildings of a single site.  Prearranged evacuation and relocation
procedures for every selected emergency are defined, installed,
activated and controlled on a building by building basis from a
single location.  This invention involves the coordination and
activation of priority based multiple emergency procedures between
multiple buildings of a single site.  Prearranged evacuation and
relocation procedures are defined, controlled and activated on a
building by building basis from a single location.  Normally, site
security would provide this control location, and the person at the
helm is referred to herein as the Emergency System Controller (ESC).

      A component of this invention involves predefined and
prioritized emergency types.  Some possible emergency types are fire,
bomb threat, flood, tornado, explosion, internal assault, external
assault, earthquake and hurricane.  These emergency types can occur
for any one or more buildings on a campus.  Other possible
emergencies which are building specific might also be included with
the invention described here.  For instance, one building on a campus
might possibly have radiation equipment or another have highly toxic
chemicals.  Every emergency type has a defined priority relationship
relevant to all other emergency types.  For instance, a fire
emergency would have priority over a bomb threat, and a toxic
chemical leak would override an earthquake.
