RULA evaluation indicates that all MMH methods used while lifting the materials achieves a score of 7 for all
workers. This final result is based on two main score values; arm and wrist for the first one and neck, posture and
legs for the second score. High values shown on arms and wrist (7 to 8 range) which indicates a high risk. Range for
neck, posture and legs were 6 to 11. This shows that it is high risk for MSD problems and can be clearly observed
from the task they do as illustrated in Figure 3. Combination of values of upper and lower muscles as well as
postures in the MMH activities gave a value of seven, which is in level 4. This means that the current MMH method
is required to be investigated and changes are required as soon as possible. This result proves that the information on
LBP and MSD problems obtained from BPSS have a clear and direct connection with the MMH activities
performed
