The correct assertion is that elevators servicing both the floor of the Fire Warden and the fire floor must not be used under any circumstances during a fire emergency. This guideline is critical for ensuring the safety of occupants and emergency responders. Elevators can become unsafe due to the potential for malfunction, power failure, smoke, or flames that can compromise their operation.

When considering the risks during a fire, using elevators may trap individuals inside or lead them directly to a fire floor, which can increase the chances of injury or fatalities. The stairwell provides a safer means of evacuation, as it is designed to remain clear of smoke and enable emergency personnel to access different floors without the hazards associated with elevators. Therefore, it is imperative for the Fire Warden and all personnel to adhere to this protocol for the safety of everyone in the building.
