——s a ae eee This research study is conducted at small scale industry situated at MIDC Wardha (Maharashtra). The 15 workers were selected for study of average stature 168.34 cm + 2.69 S.D., average age 35.8 years + 3.02 S.D., average weight 63.6 kilograms + 6.66 S.D. and average experience 112 years. The video recording of their postures showing movements of the workers during working was recorded. After footage the video, it was cropped to get snapshots for the analysis of posture of the worker. Snapshots of 15 workers performing their work were obtained. The snapshots were analyzed to fill the scores in RULA and REBA; score sheets (appendix). The first step was overall body posture assessment using REBA method. The works with the involvement of high risk were scored higher and those with less risk involvement were scored 0. Immediate corrective actions and necessary changes were recommended for activities scored higher to keep away from any risk.

FIGURE 3: Assignment of REBA Score according to position of body part (Source: Ergointelligence™ Software.) The assessment using RULA worksheet is presented in appendix. Table | presents the differen categories of the risk levels as obtained after analyzing the posture. TABLE 1: Categorization under RULA Level Using the REBA analysis method, it was observed that the major parts of the workers were working in unacceptable posture at high risk levels.
