Which component's position is determined by viewing the mast from specific positions?

• A. Platform Gate
• B. Call/Send Control Station
• C. Interlock Wiring
• D. Platform Hand

Answer: (D)

Visual checks for certain movable parts use reference points on the mast. The platform hand is a part that moves with the platform edge, and its exact position isn’t easy to judge from a single viewpoint. By looking at the mast from specific, fixed positions, you can see how the platform hand aligns with the mast’s reference marks or connectors. Those visual cues let you determine whether the platform hand is in the correct extended or retracted position, which is crucial for safe operation and proper interaction with other safety components. The other items aren’t read this way: the gate’s status, the call/send station, and the interlock wiring are inspected or inferred through different indicators or electrical tests, not by watching the mast for position.
