Who uses "Bypass" settings to service an elevator during emergencies?

The use of "Bypass" settings during emergencies is primarily the responsibility of elevator mechanics. These professionals are trained specifically to understand the operational functions and safety protocols associated with elevators. In emergency situations, such as fires, elevator operations may need to be altered to ensure the safety of both individuals and emergency responders.

When elevators are set to "Bypass," it means that the normal control system is overridden, allowing the elevator to operate independently of its usual automated controls. This can help in moving personnel safely to different floors or returning the elevator to a specific location for safe evacuation, while preventing it from stopping at floors where emergency conditions exist.

Elevator mechanics are knowledgeable about the technical aspects and potential hazards of elevator operation, making them the appropriate personnel to handle such settings. Firefighters and safety officers focus on overall emergency response and safety management, and dispatch operators handle communication and logistics, rather than directly interfacing with the elevator systems.
