Short answer: This is a zone or room from which evacuation is carried out and supervised. Safety lighting is implemented so that sufficient illuminance is provided for safe evacuation. The duration of this lighting must be longer than the maximum evacuation time. This is typical for physical and technical security rooms, rooms for fire-protection personnel, gatehouses, etc.
