Based on RULA observations on work stations and MMH motions, it was found that the MMH methods used is
on level 4. This means that the current method employed should be investigated and immediate changes should be
applied. Should this method is continued, a higher risk of LBP and MSD could occur. The management should
emphasize on the design of the work stations as well. A good design should minimize the requirement of MMH
activities that consumes high amount of energy, such as the implementation of conveyors and rails to transport raw
material to the furnace.
