In evacuation design, which rule helps ensure people can exit quickly and safely?

• A. Doors to Open in the Direction of Escape
• B. Sliding or Revolving Doors Should Be Used
• C. Emergency Routes and Exits
• D. Exit Routes Require No Signs

Answer: (A)

In evacuation design, how a door behaves at an exit directly affects how quickly people can get out. Doors that open in the direction of escape prevent the door from becoming a barrier as crowds push through, which reduces delays and bottlenecks. Outward-opening doors and those with panic hardware let occupants push through quickly even in a crowded, stressed situation, supporting a smooth, continuous flow to safety. Revolving or sliding doors can trap people or slow them down during an evacuation, making them less reliable in emergencies. While having clear emergency routes and exits and proper signage is important, the specific rule that directly improves exit speed and safety is ensuring doors open in the direction of escape.
