How quickly can the hangar bay doors close to isolate fires?

The hangar bay doors are designed to close rapidly in order to contain and isolate fires effectively within the aircraft hangar. The specified time of 18 seconds for the doors to shut is crucial because quick containment helps prevent the spread of fire and smoke, ultimately safeguarding both personnel and equipment. This rapid response reduces the potential for damage and allows firefighters to manage the situation more effectively. The design of these systems prioritizes speed and efficiency in emergency scenarios, thereby demonstrating the importance of maintaining safety standards in aviation environments. The chosen time reflects established protocols for emergency response in hangar operations.
