An Evaluation of Work Posture and Musculoskeletal Disorder Risk Level Identification for the Fireworks Industry Worker's

In the Firework industries, workers are affected by muscle, nerve, spinal cord, leg pain, or ligament injuries depending on the work nature and work pressure. During the festival or seasonal times, workers are forced to complete their tasks. For that period, supervisors and managers are likely to add to some tasks or increase their workload. They must work for longer durations and use excess hand and arm muscles, resulting in poor body posture. Musculoskeletal disorder (MSD) develops, as a result, causing pain and discomfort. But this may expose workers to workplace musculoskeletal conditions that lead to health complications and financial losses if endured over time. The current study objective is to find musculoskeletal disorder issues among the firework industry employees. Use the KNN rule to analyze the connection between musculoskeletal pain issues and risk factors, as well as work postures. The model will classify the poses supported that predicting the kind of disorder with accuracy and effectiveness. The results is used as a decision support tool to prioritize resources that can reduce ergonomic risk.
