Explanation:

Presence - sensing devices are specifically designed to detect the presence of a person (in this case, a worker) in a particular area. Safety trip controls are more about stopping a machine when a certain condition is met (not just sensing presence). Pullback devices are related to pulling parts of the body away from danger (not sensing presence). Restraint devices are for holding a person in place (not sensing their presence in an area).

Presence Sensing
