Best Practices: 

•    Install and maintain lights to illuminate working places during the night and early morning hours.
•    Install berms, signs or devices to identify the edge of working benches and to allow equipment operators to maintain control of equipment.
•    Train equipment operators to identify dangerous conditions and to keep the dozer blade between the operator and the edge when near drop-offs.
•    Develop and enforce policies requiring safety belts when operating machinery.

Additional Information: 

This is the 24th fatality reported in 2020, and the eighth classified as “Machinery.” (* Italicized details added by safeminers.com from MSHA data)
