Rigging Assignment Names: Case History #1 Worker Killed When Struck by Falling Exhaust Stack Shipyard workers were using a wheel-mounted crane to reposition two exhaust stacks  that had been removed from a vessel. The exhaust stacks were being placed close to  each other while they were being prepared for sandblasting and painting. The crane  operator placed one exhaust stack on its side and leaned the second stack against it  while preparing to move the second stack onto its side. The crane operator then  slackened the line so that a rigger could reposition the wire rope. As the rigger  approached the second stack, the 3-ton exhaust stack fell over and struck the rigger in  the back of the head, killing him instantly.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
