The Y-Junction area track sections are hydraulically operated and electronically actuated. After power shutdown, these sections are considered what type of hazards?

• A. Electrical hazards
• B. Crushing hazards
• C. Fire hazards
• D. Slipping hazards

Answer: (B)

When power is removed from hydraulically operated, electronically actuated track sections, the mechanical energy in the system becomes dangerous because the moving parts can shift or collapse unpredictably. Hydraulic actuators may still contain stored energy or valves can fail in a way that causes sudden movement, and the weight of the track sections can drive them together or into fixed structures. This creates pinch points and crushing hazards for anyone working nearby or between sections.

So, in a shutdown condition, the primary risk is being crushed by moving track components, rather than fire, slip, or an electrical hazard.
