The above graph shows the RULA and REBA Scores for 10 subjects, it indicates that posture scores of most
workers are well above the assumed safe scores hence immediate change or ergonomic intervention is needed in the current
workplace. Rapid Entire Body Assessment (REBA) (Hignet and McAtamney, 2000) and Rapid Upper Limb Assessment
(RULA) (McAtamney and Corlett, 1993) working posture analysis were used to analyse the postures and the associated
risks. REBA scores (Table 1) were very high (11/11) in the sections where log shifting is done manually by the workers.
RULA scores were consistently high in all the sectors. Average RULA score was 6 and Strain Index (Moore and Garg,
1995) was applied to get an insight into repetitiveness of the job and the resulting strain on the limbs. Value was very high in
the sharpening operation on the saw blade (70), The results of this study revealed that the saw mill workers are engaged in
rigorous hand intensive jobs, leading to various MSDs primarily affecting the upper extremity of the body. It can be
observed from the present study that work-related incidents affect different body parts of the workers. This has also lead to a
high rate of workday loss. It has also been observed that unskilled workers fail to keep their commitments because of
absenteeism.
