Texto original en inglés de la MSHA

Lee G. Mackay, a 56 year old Crusher Maintenance Mechanic, died on March 14, 2018, while helping install a discharge chute assembly on a vibrating screen deck. As a crane operator lowered the discharge chute assembly, it wedged between the surrounding steel structures. Mackay and another miner tried to pry the chute assembly loose, and the victim suffered a fatal head injury when the discharge chute assembly shifted. The accident occurred because management did not have policies, procedures and controls for persons installing and removing discharge chute assemblies on vibrating screen decks, including not working under suspended loads.

1. Management did not have policies, procedures and controls for miners removing and installing discharge chute assemblies, on vibrating screen decks.

   Acción correctiva: The company developed policies, procedures and new training materials for safely changing discharge chute assemblies. The workforce at the mine was retrained using the new policies, procedures and training materials, with additional emphasis on not working underneath suspended loads.
