Why were so many casualties of the fire from 9th floor?

Many casualties from the fire were reported on the 9th floor due to a combination of factors, including the rapid spread of flames and smoke, which can trap occupants and hinder escape routes. Additionally, the design and layout of the building may have limited access to safe exits, and the lack of adequate fire safety measures could have exacerbated the situation. Panic and confusion during the emergency likely contributed to the difficulty in evacuating effectively.
