Which statement about exit door hardware is true?

• A. A standard exit shall have fastenings or hardware that can be opened from the inside by pushing against a single bar or plate or turning a single knob or handle.
• B. Exits shall have locks that require a key from inside.
• C. Exits must have doors that swing inward only.
• D. Exits must have electronic access with a code.

Answer: (A)

The main idea is that exit doors must be easily and quickly opened from inside during an emergency, without needing keys or special effort. This is why the described hardware—a single bar or plate that can be pushed, or a single knob or handle that can be turned—best fits. It allows immediate egress with one simple action, which is the essential safety feature for exit doors. Locks that require a key from inside would hinder quick escape, which is why that option isn’t correct. Exits swinging inward only isn’t a universal requirement and can be impractical in many situations. Requiring electronic access with a code isn’t mandatory either; such access can be allowed as an option, but it’s not the standard that ensures immediate, inside-originating egress.
