## Narrative

Glenn was working on a project of replacing a conveyor in our Quarry. He was climbing a 3-foot, 3-rung ladder on the east end of the new conveyor.  His left foot was on the top of the platform and his right foot was on the top rung of the ladder when the ladder slipped out, he could feel his left knee twist, before he caught his balance.
