Which statement about exit doors is correct?

• A. Revolving, sliding and overhead doors are permitted to be used as an exit door
• B. Exit doors must always be locked from the outside
• C. Standard exit doors must be readily operable from the egress side without the use of a key or special knowledge
• D. Doors must be left unlocked during business hours

Answer: (C)

Exit doors must be readily operable from the inside during an emergency, without needing a key or special knowledge. This ensures people can exit quickly and without confusion when time is critical. That’s why the statement about standard exit doors being readily operable from the egress side without the use of a key or special knowledge is the best choice. If a door required a key, code, or unfamiliar procedure to open, it could block or slow people during an evacuation, creating a dangerous delay. Why the other ideas don’t fit: revolving doors are not allowed as required exit doors because they can trap or slow occupants in a panic and aren’t reliably opened from the inside during an emergency. The notion that exit doors must always be locked from the outside contradicts the need for immediate egress. And requiring doors to be left unlocked during business hours ignores security and safety realities where controlled access is needed while still preserving easy egress.
