When should we scale down loose material on a highwall?

• A. Immediately
• B. At the end of shift
• C. After inspection
• D. Only during rain

Answer: (A)

Immediate scaling of loose material on a highwall is essential because rock and debris can fail at any moment and pose a direct risk to nearby workers and equipment. Removing it right away minimizes exposure and helps keep the highwall area stable throughout the shift. Waiting until the end of the shift allows time for additional movement or weather effects to worsen the hazard, and waiting for an inspection or only scaling during rain leaves workers exposed to potential rockfalls in between checks. By addressing loose material promptly, you maintain a safer work area and reduce the chance of unexpected falls.
