Which statement is NOT among the four requirements of a standard exit?

• A. Shall be level with the floor
• B. When open, it shall not block any part of the required exit width of any other exit.
• C. Shall swing outward or toward the natural means of egress (unless under 50 patrons)
• D. Must have a sign indicating 'Fire Exit'

Answer: (D)

Understanding how an exit door must function during an emergency is the focus here. The four standard requirements describe practical, safe operation of the door and its placement to ensure unobstructed and efficient egress: the door should be level with the floor to avoid tripping, when opened it must not block the width of any other required exit so multiple paths remain usable, and it should swing outward or toward the natural means of egress (with some small-occupancy exceptions). These criteria are about how people move through the doorway under emergency conditions. Having a sign indicating "Fire Exit" is important for locating an exit, but it isn’t part of those four functional criteria governing how the exit door operates. Signage is a separate life-safety requirement, not a defining feature of the standard exit’s operation.
