Hazard	Risk	Control Measures
Falling rocks/debris	Injury to personnel below	Establish a clear exclusion zone. Use spotters to warn of falling material. Scale from top to bottom whenever possible. [1]
Instability of highwall	Highwall collapse, potential for burial	Conduct thorough geotechnical assessment. Implement proper slope support techniques. Monitor highwall for signs of instability (cracks, bulging).
Dust inhalation	Respiratory irritation, silicosis (long-term)	Use respirators (NIOSH approved). Implement dust suppression methods (water spraying). [2]
Slips, trips, and falls	Injuries from loss of balance	Ensure good footing. Wear appropriate footwear. Use fall protection equipment when working at heights.
Manual handling of tools	Musculoskeletal injuries	Use proper lifting techniques. Take frequent breaks. Rotate tasks to reduce strain.
