Stored ceiling tile pallets are placed directly in front of a switchgear lineup on the day of startup. What should the superintendent require before energization work proceeds?
Correct Answer
A) Remove the stored material and restore the required electrical working space
Required electrical working space must be kept clear so qualified workers can operate and service the equipment safely. Other choices leave an access hazard or postpone a condition that matters before energization.
Why This Is the Correct Answer
Required electrical working space must be kept clear so qualified workers can operate and service the equipment safely. Other choices leave an access hazard or postpone a condition that matters before energization.
Why the Other Options Are Wrong
Option B: The superintendent should leave the pallets if the disconnect handles are visible
Visible handles do not make the work area usable; pallets still block the space qualified workers need during startup.
Option C: The superintendent should move only combustible pallets and leave metal carts
The hazard is blocked access, not only combustibility; metal carts can obstruct switchgear operation just as much as combustible pallets.
Option D: Energize first and clear the space during punch work
Energization work should not start with a known access obstruction that can be corrected before startup.
