EE was helping 2 other employees lift a 30-40lb bolt bin on top of another shorter bin. He grasped the bin with both hands from the back side of the bin. While lifting, one of the ends of the bin slipped down causing EE to grip tighter. This motion caused a strain to EE's bicep. EE was taken to a clinic for the injury on 7/22 where they restricted his duty until 7/25.
