Fall to the walkway or working surface
I was on bench #3 explaining to another employee where I wanted EE to come up and pull material from (EE was on our loadout level). EE said could not see me very well so I told EE hold on a second while I repositioned myself so that EE could see me. When I moved to another spot, I slipped in some wet material causing me to fall very quickly and landed on my shoulder.
