Why are "interlocks" important for elevator safety?

Interlocks are crucial for elevator safety primarily because they ensure that the elevator cannot operate unless the doors are properly closed. This safety mechanism serves to prevent accidents that could occur if an elevator were to move while the doors are open, which could pose a serious risk to passengers. By requiring that the doors be fully closed and securely latched before the elevator is allowed to move, interlocks provide a vital layer of security and help to protect individuals from potentially dangerous situations, such as falling out of the elevator shaft or being injured as the car ascends or descends.

Interlocks act as a fail-safe to ensure that the elevator's operation is strictly controlled, enhancing the overall safety measures within the elevator system. This is critical in urban environments like Los Angeles where high-rise buildings frequently have large numbers of elevators in constant use.
