This study results help in minimizing the awkward postures, thereby reducing the health-related risk. This will also increase the efficiency of the worker and his productivity.

This study aims to quantify the prevalence of work-related musculoskeletal disorders (MSDs) and risks among workers in pump manufacturing industry. Workers from pump manufacturing industry were mostly affected by musculoskeletal injury and prolonged work nature and poor workplace environment. Data were collected with the help of the Nordic musculoskeletal questionnaire and by direct observations. The statistical analysis carried out reveals that 67.39% of pump manufacturing industry workers reported MSDs. The highest prevalence rate has been found in the feet (48.26%). In total, 46 workers from different age, experience workers were considered for this study. Age, experience, marital status, stress in the job were the risk factors which significantly (p < 0.05) associated with the reported MSDs. Among the different factor for getting fatigue, the workers reported with the maximum discomfort during work at awkward posture (60.9%) with Odds ratio as 9.486 and 95% CI is 2.277-39.036. Sociodemographic factors, awkward posture and repetitive movements contribute to cause MSD among pump manufacturing workers. Results suggest that to undertake further studies on different preventive measures and ergonomics intervention to reduce the risks of LBP among workers in pump manufacturing industry.

BACKGROUND: Work-related musculoskeletal disorders (WMSDs) are prevalent and have an impact across occupations. However, there are very few studies that document the prevalence of WMSDs in the pump industry. In manufacturing industries, the common issue for WMSDs and physiological stress among the workers is caused by poor working posture. OBJECTIVE: To investigate the occupational risks at the winding station in the pump manufacturing industry. In addition, this study examined the influence of work-study on mitigating occupational risks. METHODS: Workers who were involved in circular coil winding and insulation testing were considered for the study. Awkward postures adopted while performing these tasks cause fatigue, injuries and WMSDs. Tasks were evaluated as per the National Institute for Occupational Safety and Health (NIOSH) standards. A work-study was conducted to better understand the workflow. Virtual ergonomic postural evaluation (Rapid Upper Limb Assessment, RULA) was used to identify the occupational risks. RESULTS: Time taken for making circular windings and insulation testing (7.5 Hp submersible motor) was found to be 4.04 minutes and 0.95 minutes, respectively. A CAD model was used for ergonomic evaluation in the virtual environment. The RULA final score of 2 and 3 is attributed to coil winding and insulation testing. CONCLUSION: For further studies, the whole pump manufacturing process should be taken into account. The ergonomic tools used in this study will considerably reduce the occupation risks at the winding station in the pump manufacturing industry.
