Handloom weaving, as one of India's oldest cottage industries, plays a significant role in the country's rural economy. It provides employment opportunities for a vast majority of rural workers. However, the nature of this industry is largely unorganized, and workers often face occupational health issues, particularly musculoskeletal disorders, due to prolonged working hours and adverse work postures. This article aims to explore the prevalence of musculoskeletal disorders and associated risk factors among silk saree workers, highlighting the ergonomic concerns in handloom weaving.
Study Methodology:
The study examined 206 silk saree workers using a modified Nordic Musculoskeletal Questionnaire method to assess the prevalence of musculoskeletal issues and identify associated factors. Additionally, ergonomic assessments were conducted using the Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA) techniques. These assessments helped identify risk variables and evaluate the impact of work postures on musculoskeletal problems during various stages of silk saree manufacturing.
Findings and Results:
The study revealed significant concerns regarding musculoskeletal disorders among handloom workers. The following are the key findings:
Yarn Extraction: Fifty percent of workers were found to have a very high risk of musculoskeletal issues during the yarn extraction process. This stage involves physically demanding activities that can strain the back, shoulders, and wrists.
Yarn Pre-Preparation: Approximately 73.33% of workers involved in yarn pre-preparation were identified as having a very high risk of musculoskeletal disorders. This process often requires repetitive motions and prolonged periods of sitting or standing, leading to strain on the neck, shoulders, and upper limbs.
Dyeing: A staggering 75.75% of workers engaged in dyeing reported a very high risk of musculoskeletal problems. The nature of this process involves heavy lifting, prolonged standing, and awkward postures, which can lead to back, shoulder, and wrist injuries.
Weaving: During the weaving process, 55.78% of workers were found to be at a very high risk of musculoskeletal disorders. This stage requires repetitive motions and sustained periods of sitting or standing, leading to strain on the neck, shoulders, and lower back.
Specific Process Risks:
Additionally, the study identified high risks in the following specific processes:
Warp Yarn Preparation: Forty-five percent of workers engaged in warp yarn preparation were found to experience high risks. This stage involves activities such as winding and stretching yarn, which can strain the upper body and cause repetitive strain injuries.
Weft Yarn Preparation: Approximately 78.05% of workers involved in weft yarn preparation were identified as having high risks. The nature of this process often requires repetitive motions and prolonged periods of sitting or standing, leading to strain on the neck, shoulders, and upper limbs.
Drafting of Warp Yarn: One hundred percent of workers involved in drafting of warp yarn reported high risks. This stage involves activities such as twisting and aligning yarn, which can strain the wrists, shoulders, and upper back.
The findings of this study highlight the urgent need for ergonomic interventions in handloom weaving to address the prevalence of musculoskeletal disorders among workers. The identified risks during various stages of silk saree manufacturing emphasize the importance of implementing ergonomic design principles and promoting healthy work practices. Employing techniques like REBA and RULA can aid in identifying risk factors and developing strategies to mitigate them. By prioritizing worker safety and well-being, the handloom industry can enhance productivity, reduce absenteeism due to work-related injuries, and create a sustainable environment for the future of this traditional craft.
