IRJET, 2022
o examine the workers in the foundry industry’s subjective self-evaluation of musculoskeletal discomfort is the major goal of this research article. Fifty workers between the age of 18 and 55 took part in this study. The highest and the lowest percentage of the workers those are experiencing at least of one discomfort are 86 percent and 52 percent respectively due to pain in different parts of the body such as physical exertion, lifting loads, posture, work space, job rotation, rest period, and repetitive motion that has been revealed in the report of questionnaire survey. In addition, 17 of the 20 dissatisfaction factors scored higher than the average musculoskeletal discomfort score of 2.5 on a 5-point scale. Additional research, have been done according to the finding of this study that a relation between musculoskeletal pain and its impact on the employees in the foundry environment is required in this study. To give an ergonomic evaluation based on the postural analysis to reduce the risk of ergonomics this study has been proposed. This document has given a description about the different postures, origins and discomfort related to work in foundry industry. To determine the percentage of people who are suffering from such musculoskeletal disorder a special type of questionnaire called as cornel musculoskeletal disorder questionnaire are used. To determine which tool may be utilized to decrease this risk and establish a safe workplace that will increase the productivity an analysis techniques of ergonomics risk factor are identified.
Prevalence of Musculoskeletal Discomfort Among Workers in a Medical Manufacturing Facility
International Journal of Automotive and Mechanical Engineering, 2021
Medical manufacturing has shown great growth potential in Malaysia, and this sector has created numerous jobs for both local and foreign workers. The workers involved in this industry are exposed to ergonomic risk factors, which lead to discomfort in different body parts. Despite the numerous studies on occupational hazards and the prevalence of Work-Related Musculoskeletal Disorders (WMSDs), little is known about the prevalence of WMSDs for workers working in the medical manufacturing facility, especially in Malaysia. Thus, the main objective of this study is to identify the prevalence of WMSDs among workers in the selected medical manufacturing industry in Malaysia. Structured interviews using Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) were conducted among 10 male workers (mean age of 44 ± 10.83 years, age range of 24–55 years, and working experience range of <1–27 years). The results indicate that the workers experienced the highest discomfort in three body parts;...
Musculoskeletal disorders and ergonomic risk factors in foundry workers
International Journal of Human Factors and Ergonomics, 2019
The present study aims to identify activity-specific risk factors associated with musculoskeletal disorders (MSDs) among workers from small-scale foundries in western India. The modified Nordic questionnaire is adopted to explore the prevalence of MSDs and associated critical ergonomic risk factors among 181 male foundry workers. Further, logistic regression is applied to explore critical factors causing MSDs in a foundry context. This study investigates manual materials handling (MMH) effect on MSDs prevalence and highlights 'load-handled' as the most critical risk factor. In the process, the study emphasises lower back, neck and knee as the vulnerable body parts. Additionally, it was investigated that workers from melting sections of the foundries are prone to MSDs risks that require immediate intervention. A work system model was used to frame the study and interpreted the results in the context of human-machine interaction occurring at the workspace. The results can be further coupled with engineering interventions for improved productivity in the foundry. 2 A. Qureshi et al.
Objective: Identify the presence of ergonomic risk factors and their relationship with upper limb musculoskeletal discomfort in workers in the packaging area of a food processing company in Guadalajara. Material and methods: Observational, cross-sectional, comparative study in 39 workers who pack sausages, 21 in the T1 machine and 18 in the M2. The hypothesis raised is that there is a greater ergonomic risk and repercussion on the health of the workers of the T1 machine compared to the M2 machine. Those who were 3 months old were included and those who had another job were excluded. The data was obtained by a sociodemographic data questionnaire and labor items, the Disabilities of the Arm, Shoulder and Hand (DASH) Questionnaire and the Job Strain Index (JSI). Results: 69% of the participants were men and 31% women. When evaluating repetitive movements with the Work Tension Index method, results were found outside safe ranges, being higher in T1. 42.8% of workers affected 40% of disability, being higher among T1 operators (P = 0.038). 31% reported moderate to very painful discomfort. Conclusion: The hypothesis was verified by finding the relationship between upper limb disability in T1 machine operators (P 0.0294).
Ergonomic intervention to reduce musculoskeletal disorders among flour factory workers
Work, 2020
BACKGROUND: Work-related musculoskeletal disorders are the most common occupational health hazards. In the flour production industry, the fast pace of work, high frequency of repetitive movements, manual handling of loads, and awkward postures put a lot of pressure on the worker's body. OBJECTIVE: Given the high exposure of the workers of the flour production industry to ergonomic risk factors, this study aimed to reduce the rate of musculoskeletal disorders among a group of flour factory workers through ergonomic interventions. MATERIALS AND METHODS: This interventional study was performed using the census method on the eligible workers of a flour factory. An ergonomic intervention program was planned and implemented with the goal of reducing musculoskeletal disorders. The effectiveness of the program was evaluated by measuring the prevalence of musculoskeletal disorders before and six months after the interventions. RESULTS: Before the intervention, musculoskeletal disorders were most prevalent in the lower back, arms, shoulders, legs, thighs, knees, neck and wrists, respectively. Evaluation of the prevalence of musculoskeletal disorders after the intervention showed the positive effect of the ergonomic intervention program on musculoskeletal disorders in the neck, shoulders, lower back, thighs, knees, and legs (P < 0.05). CONCLUSION: Engineering and management interventions implemented in this study led to a significant reduction in the level of ergonomic risk factors and a reduced rate of musculoskeletal disorders among workers of different units in the flour factory.
