What is defined as a "point-of-operation guard"?

A point-of-operation guard is specifically designed to protect workers from the hazards associated with the zone where the machine actually performs its work. This area is often where hands, fingers, or other body parts could become entangled in machinery during operation.

B correctly describes this where it states that the guard removes access to the operational area, effectively preventing personnel from being able to reach into this hazard zone while the machine is running. This type of guard is essential for ensuring that operators are safeguarded against potential injuries caused by the machine's moving parts or operations, reinforcing safe work practices around machinery.

The other descriptions do not accurately convey the purpose of a point-of-operation guard. For example, while a barrier around the machine's outer edges may serve to limit access to the machine overall, it does not specifically address the hazards at the point of operation. Similarly, a protective device for moving parts or a safety shield for electronics does not directly relate to the operational zone where active work is being done. These fail to highlight the specific focus on preventing access to the area where actual operations occur, which is the main function of a point-of-operation guard.
