What is an unsafe practice during fire emergencies?

Using elevators to evacuate during a fire emergency is considered unsafe because elevators can become inoperable or malfunction during a fire. In addition, they may stop at floors where the fire is present, potentially trapping occupants. Elevators can also be affected by smoke, heat, or electrical failure, which increases the risk of injury or death. The safest method of evacuating a building during a fire is to use the designated stairways, which are specifically designed for emergency egress and are typically equipped with fire-resistant features to protect occupants as they exit the building. The other options promote safety and preparedness during emergencies, which further emphasizes why using elevators is not an appropriate action in such situations.
