This study aims to estimate the fatigue index of pump assembly operation. Workers from pump assembly operation were mostly affected by musculoskeletal injury due to prolonged work nature and poor workplace environment. Data were collected with the help of the Nordic musculoskeletal questionnaire and direct observations. The statistical analysis carried out reveals that 67.39% of pump assembly operation workers reported MSDs. In total, 46workers from different age, experience and more number of factors were considered for this study. Based on this study the most painful and fatigue muscles were identified. The clinical test of muscles was conducted for locating Electromyogram (EMG) electrode. The data collected from EMG were processed in lab Chart, which gives the relationship between cycle and Fatigue index. The critical point time, when the employee enters into the fatigue zone was identified and highlighted in the plot between cycle and fatigue index.
