What is an example of a point of operation safeguard?

A point of operation safeguard is a specific type of safety device designed to protect workers from the hazards associated with the immediate area where materials are being processed or manipulated. In this context, pressure sensing pads are a prime example of such a safeguard because they are installed at points of operation on machinery, helping to detect the presence of a person and automatically halt operations if someone stands on or applies pressure to these pads. This mechanism protects workers from being injured by machinery during its operation.

On the other hand, governors are devices employed primarily to control the speed of machinery but do not directly protect workers at the point of operation. Emergency levers generally serve as a means to shut down a machine in case of an emergency, rather than actively preventing access to hazardous areas. Safety goggles provide personal protective equipment (PPE) to protect the eyes from flying debris or harmful substances but do not function as a safeguard at the point of operation. Thus, pressure sensing pads clearly align with the definition of a point of operation safeguard, making them the correct choice in this scenario.
