A worker for a cement company went to a mill area to insert a heat blank into an inlet duct, which is positioned near a dust collector screw conveyor. While inserting the heat blank, the worker placed one leg on top of the screw conveyor, which has a rotating shaft that has a metal flag on it that passes a motion sensor. His pants leg got caught on the rotating flag, pulling his foot and leg into the area. He sustained multiple injuries to the foot and leg, which required hospitalization. The MOL investigation found that although the screw area was guarded, the rotating shaft with the metal flag wasn’t guarded to prevent access to it. The company pleaded guilty to a guarding violation and was fined $50,000 [Essroc Canada Inc., Govt. News Release, May 5, 2017].
