A team of four employees were replacing a chemical pump. When the pump was replaced, the team began to dismantle the setup. Team member 1 was taking down a come-along when he slipped and grabbed onto a nearby strap to regain his balance. This caused a bar to fall directly onto the hand of the injured employee who was replacing a pump eyelet below the bar and come-along assembly. The injured employee received a right thumb laceration, fracture and tendon separation. As a result, the right thumb was partially amputated.
