The failsafe principle is a design concept employed in engineering and technology to ensure a system or device defaults to a safe state in the event of a failure or malfunction. This safe state is typically one that minimizes harm to people, equipment, or the environment. The core idea is to anticipate potential failure modes and design the system so that when such a failure occurs, it automatically transitions to a pre-determined secure condition rather than continuing to operate in a potentially dangerous manner.

Implementing a failsafe mechanism often involves redundant components or systems. If a primary component fails, a backup takes over. Another common approach is to use mechanisms that require continuous input or energy to remain in an operational state. If this input or energy is lost due to a failure, the system reverts to a safe, inactive state. Examples can be found in many areas, from industrial control systems and medical equipment to automotive safety features like airbags. The objective is to prevent catastrophic outcomes by ensuring that any deviation from normal operation leads to a controlled and secure shutdown or reset.
