What is the primary purpose of the Object-Free Area at Midway Airport?

The primary purpose of the Object-Free Area at Midway Airport is to serve as an emergency evacuation walkway. This area is crucial for ensuring safety by providing a clear and unobstructed space around runways and taxiways. In the event of an emergency, having an Object-Free Area allows for quick and safe evacuation of personnel and passengers away from aircraft incidents or unforeseen situations.

This area is specifically designed to minimize the risk of accidents and improve response times during emergencies. The clear space helps in facilitating the movement of emergency responders and equipment, allowing them to access and manage an emergency situation effectively without obstacles in their way.

The other options do not reflect the primary function of the Object-Free Area, as it is not designed for recreational space, equipment storage, or concession activities. Each of these functions is important in its own right but does not align with the critical safety objectives that the Object-Free Area is meant to fulfill.
