The low location lighting is an unique system that allows all evacuation routes to stay illuminated, thereby communicating a clear, continuous and unambigous 'means of escape' message which lead to a safe place. The locations of fire fighting equipment are also clearly marked as part of the system along the escape routes. This reduces possible confusion and panic, factor that hamper the safe egress from occupied areas.
