What action is required if the discharge chute becomes clogged during transfer of concrete?

• A. Stop discharge and clear the obstruction safely, then resume only when flow is restored.
• B. Immediately shake the truck to dislodge blockage.
• C. Continue discharge at a lower rate without clearing.
• D. Notify the producer and continue.

Answer: (A)

When a discharge chute becomes clogged, the priority is safety and control of the concrete flow. Stop the discharge and clear the obstruction using proper, safe procedures, then resume only when the flow is restored. This prevents back-pressure, spills, and potential injuries from sudden release or improvised attempts to dislodge the blockage. After clearing, verify the chute is clear and the concrete is flowing smoothly before restarting. Shaking the truck or continuing at a reduced rate without clearing, or simply notifying the producer and proceeding, does not address the immediate hazard and can lead to equipment damage or unsafe conditions.
