Elevators may be used during a fire if the Fire Warden is informed by whom that one bank is unaffected?

The correct answer highlights the critical role of communication in emergency situations, particularly regarding the use of elevators during a fire. The Fire Command Station is responsible for coordinating responses during an emergency, including evaluating the safety of various building systems, such as elevators.

For safety protocols to be followed, the Fire Command Station obtains real-time updates about the conditions in different areas of the building. If they confirm that one bank of elevators is unaffected by the fire, they can officially inform the Fire Warden, allowing the use of those elevators for evacuation or other emergency purposes.

Using information from the Fire Command Station ensures that decisions are made based on up-to-the-second assessments of the situation, mitigating the risk of using elevators that may be unsafe due to the fire conditions.
