When constructing a new stockpile with a dozer pushing material over an edge, what is the safest practice to prevent undermining the equipment?

Question: When constructing a new stockpile with a dozer pushing material over an edge, what is the safest practice to prevent undermining the equipment?

Answer options: ✅ Always maintain excellent visibility of the dozer's tracks and the ground directly ahead and beneath the blade, avoiding 'blind' pushing over an unseen edge.

• Ensure the dozer is always angled sideways to the edge to allow for quick escape if the ground collapses.
• Place warning pylons along the edge every 5 metres to indicate the drop-off point.
• Utilize a spotter who stands at the base of the pile to guide the dozer operator.

Correct answer: Always maintain excellent visibility of the dozer's tracks and the ground directly ahead and beneath the blade, avoiding 'blind' pushing over an unseen edge.

Explanation: Maintaining clear visibility of the ground directly beneath the equipment and anticipating the structural integrity of the pile's edge are paramount to prevent undermining and potential tipping or engulfment, as per safe dozing practices on stockpiles.
