In uncritical systems, an unnecessary accident is born through a humdrum failure, or it throws in a human possibility for inadvertent harm. The objective of these systems is so that at the moment of malfunction the system switches to a safe mode without any possibility of damages to equipment or loss of human life.

Nanometer level precision is what aerospace, medical technology, nuclear, and transport engineering demand because at such magnitudes the magnitude of an unspecified error turns into a disaster. Hence, it is of utmost consideration to have Mechanical Safety Features incorporated into the design.

Fail-safe considerations are applicable to ascertain that a critical system is reliable and stable.Thus, in the case of mechanical systems, emergency braking systems, pressure relief valves, and locking systems are designed to act immediately upon the detection of a fault.

These Mechanical Safety Features thus protect against hazardous consequences by containing the failure or isolating the problem before it gets out of hand.

Besides, implementing fail-safe mechanisms would also go towards satisfying regulatory requirements and building confidence in the system by the end user. Indeed, in modern engineering, it is considered a good practice, if not a necessity, to anticipate potential failure points and actively incorporate safety into the design process. Quite enthusiastically, in the end, fail-safe mechanisms in conjunction with mechanical safety devices ensure by their very presence that vital systems operate safely in unexpected situations, providing a secure guarantee on both assets and lives.
