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

Using "Bypass" settings to service an elevator during emergencies is primarily the responsibility of elevator mechanics. They are trained to handle the technical aspects of elevator systems and can safely ensure that the elevator operates efficiently during critical situations, such as when power is lost or there is a fire.

Elevator mechanics have the expertise necessary to manipulate the bypass settings to allow for movement of the elevator cars, ensuring that trapped occupants can be freed or allowing emergency personnel access to specific floors. They also understand the safety protocols needed to protect both the occupants and the rescue teams during emergency operations.

While firefighters, safety officers, and dispatch operators play vital roles in emergency responses, they do not typically have the specialized training required to service or reconfigure elevator systems in a crisis as elevator mechanics do. Their focus is more on rescue operations, ensuring the safety of individuals, or managing communications rather than the technical servicing of the elevator itself.
