A fail-safe lock is designed with safety considerations in mind, particularly in terms of emergency situations. During a power failure, a fail-safe lock typically unlocks to ensure that individuals can exit a building or secure area without being trapped. This feature is particularly critical in environments where safety is paramount, such as hospitals, schools, or public places, where rapid evacuation may be necessary.

Fail-safe mechanisms prioritize the safety of individuals over the security of the premises, allowing for automatic unlocking when power is lost. This design principle ensures that in the event of an emergency, such as a fire or other hazardous situation, people can access exits without being impeded by a locked door.

In contrast, a fail-secure lock would remain locked during a power failure, potentially creating a dangerous situation if individuals needed to exit quickly.
