The concept of interlocking is based on the idea of impeding an action, movement or event when the existing conditions would make it undesirable or even dangerous or preventing a substance or environmental condition coming in contact with another in a way that could be damaging to the health of people in the area. Interlocking systems are much more present in our daily lives when we deal with any type of automated systems or machinery.

An interlocking system may seem like an obstacle and a loss of time in our frenzied daily lives. More often, it represents an important safety factor. It can prevent an action resulting from inattentiveness or fraudulence from happening.
