Stephen J. Wickham, Contract Driller, age 30, was killed on November 1, 2012. Wickham was attempting to manually load a threaded drill steel into the mast of a crawler drilling machine by engaging it with the rotating drill head when he became entangled in the rotating drill steel. The accident occurred due to contract management's failure to implement policies and procedures to ensure that drillers stayed clear of a rotating drill steel, specifically while performing drill steel loading operations. Wickham had approximately six months of drilling experience and did not receive effective task training addressing the safe work procedures for loading a drill steel and the potential hazards associated with the task. Additionally, Wickham was assigned to perform work alone where hazardous conditions existed and he could not communicate with others, be heard, or be seen.

1. The victim did not receive effective task training regarding procedures to safely load drill steels. Contract management policies and procedures failed to ensure that drillers stayed clear of a rotating drill steel, specifically while performing drill steel loading operations.

   Acción correctiva: Contract management established written policies and safe work procedures to ensure that drillers stayed clear of rotating drill steels during drill steel loading operations. These new procedures incorporate the manufacturer's recommendations for loading drill steels and require a minimum of two properly trained persons to perform the task. All persons were provided task training regarding the new policies.

2. Contract management required drillers to work alone where hazardous conditions existed and they could not communicate with others, could not be heard, or could not be seen while working in the quarry.

   Acción correctiva: Contract management implemented safe work procedures for loading drill steels which incorporate the manufacturer's recommendations for loading drill steels and require a minimum of two properly trained persons to perform the task. All persons were provided task training regarding the new procedures. In addition, the mine operator has implemented policies and procedures for management personnel to provide increased oversight of contractors working at the site.
