Tower Rock Stone Company · Quemaduras por arco (eléctrico)
Miner electrician was inspecting stabs on bucket can in Motor Control Center. When re-inserting bucket in to cabinet, an insulating barrier became dislodged. This allowed the bucket to come in contact with 480 volt bus bars creating an arc flash. This resulted in 1st degree burns to miner's face and 3rd degree burns to both hands and arms.
