Panic Hardware is defined as a door-latching assembly that releases the latch bolt upon the application of a force in the direction of egress travel. Which option best reflects this definition in practice?

• A. Panic Hardware. A door-latching assembly incorporating an actuating member or bar that releases the latch bolt upon the application of a force in the direction of egress travel.
• B. A door-latching assembly that releases the latch bolt upon the application of a force in the direction of egress travel and provides fire protection.
• C. A locking device that requires a key to exit.
• D. A hinge-based mechanism for emergency egress.

Answer: (B)

Panic hardware is a door-latching assembly that unlatches the latch bolt when pressed in the direction of egress travel, enabling rapid and easy exit. In practice, this means a push bar or similar actuating member across the door that releases the latch when people push, and the hardware is listed for use on fire-rated doors to maintain fire protection while allowing quick egress. The option that mentions both releasing the latch bolt under egress force and being suitable for fire-protection doors best reflects how panic hardware is used in real buildings. The other descriptions either omit the fire-protection aspect, describe a locking mechanism requiring a key, or specify a hinge-based mechanism, which does not capture the intended hardware function.
