What is required about exit fastenings?

• A. Fastenings or hardware can be opened from the inside by pushing against a single bar or turning a single knob or handle.
• B. They must be operable only with power.
• C. They must be padlocked from the outside.
• D. They must require a key from inside.

Answer: (A)

Exit fastenings must be readily operable from the inside to allow immediate egress in an emergency. The best answer describes a device that can be opened from the inside by a simple action—pushing against a single bar or turning a single knob or handle—without needing keys, power, or special knowledge. This ensures occupants can exit quickly even in stressful situations or if power is out. Devices that require power, that are padlocked from the outside, or that require a key from inside would hinder or prevent safe egress, which is why they are not acceptable.
