A machine interlock prevents a machine from operating without the proper __________ in place.

Explanation:
Protective guarding is essential for safe operation. An interlock is a safety device tied to a guard that prevents the machine from starting or running unless the guard is properly in place. When the guard is closed or secured, the interlock allows the control circuit to energize; if the guard is opened, the interlock breaks the circuit and stops the machine. This ensures the hazardous area remains protected during operation. Buttons are used to start/stop, valves control fluid power, and switches are general control inputs, but none inherently ensure guarding like an interlock does.
