Question: Which of the following is the most critical safety consideration when performing ditching operations with a grader, especially concerning ground stability?

Answer options: ✅ Maintaining a safe distance from the edge of the cut to prevent cave-ins or machine rollover.

• Ensuring the mouldboard is always extended to its maximum reach to maximize ditch depth.
• Operating only in daylight hours to ensure full visibility of the ditch profile.
• Using a high travel speed to quickly complete the ditching pass.

Correct answer: Maintaining a safe distance from the edge of the cut to prevent cave-ins or machine rollover.

Explanation: When ditching, one of the most critical safety considerations is ground stability. Operating too close to the edge of an excavation, particularly in unstable soil conditions, significantly increases the risk of a cave-in or the grader rolling over into the ditch. Operators must maintain a safe distance from the bank's edge to ensure a stable platform for the machine, in line with provincial OHS regulations regarding excavations.
