The company dispatched my Father to a Victorville cement plant to find the cause of the death of an inside maintenance man that had been killed while working on one of the plant�s elevators. The man had been crushed in the pit while he and another maintenance man were attempting to repair the elevator. Dad discovered that the limit switches were not explosion proof and concrete dust had filled them up to the point where the finger contacts couldn�t open. A sad story for the man�s family and equally distressing for the other man who was running the elevator.
