EMPLOYEE #1 AND ANOTHER EMPLOYEE WERE ASSIGNED THE JOB OF INSTALLING GUARDS ON AN ELECTRIC WINCH AT THE TAIL END OF THE CONVEYOR. EMPLOYEE #2 AND ANOTHER EMPLOYEE WERE GIVEN THE JOB OF STRAIGHTENING A SPREADER BAR AT THE HEAD OF THE CONVEYOR. THE CONVEYOR WAS SUPPORTED BY A CRANE WHILE THE SPREADER BAR WAS BEING WORKED ON.
