A recent inspection conducted by an insurance company has identified some problems with machine guarding around the mobile conveyor system at a surface coal mine. The superintendent asks that you, a chief mechanic, conduct a more thorough inspection and document your findings. You are to report back to the superintendent with recommendations that will be part of a company-wide machine guarding policy. The superintendent assigns "Curly", who just recently became a mechanic helper, to accompany you. You are to take this opportunity to teach him safe machine guarding practices. You travel through the complex and begin to document your findings.
