Airports combine the complexities of open atriums with compartmentalize secure spaces. Therefore, the ability to securely section off smoke and fire in the case of an emergency is a necessity.
Within an airport, it is not only necessary to allow for the evacuation of current patrons, but to also allow for emergency procedures to commence prior to important staff evacuating. An air traffic control tower, for example, can’t be evacuated immediately considering the safety of those in the air rely on the air traffic controllers.
Airports will need an elaborate system of smoke containment and management in order to allow for varying evacuation times depending on location. Furthermore, by segmenting airport concourses, the effects of an emergency will be controlled as much as possible.
