All unattended exits should be locked to bar exit.

• A. True
• B. False
• C. Not defined
• D. Depends

Answer: (B)

The concept here is life safety and how it interacts with security controls. Exits that people rely on to evacuate must be readily opened from the inside without needing keys, special tools, or prolonged actions. Locking all unattended exits would slow or block people during an emergency, creating a dangerous situation and often violating fire and building codes. The proper approach is to use exit hardware (panic bars) or security devices that release during an alarm or power loss so authorized entry remains possible, while ensuring immediate egress for occupants. So, locking every unattended exit is not correct.
