Over the past few years, doctors realized that workers who carried heavy loads or maintained body positions with such loads for extended periods developed musculoskeletal problems and work environment hazards. In the long-ago years of research, the connections between specific job tasks and Musculoskeletal Disorders (MSD) with the study of ergonomics have been established. Ergonomics has become a significant contribution to the working environment to achieve or to complete the allotted work on time duration with perfection. This knowledge is necessary since the participation of all workers from the higher end to the lower end with the planning of intervention can create a suitable means of solutions in the industry. Some of the operational problems like repetitive work due to continuous sitting, standing and hazards may create fatigue. Hence, there is a need to find solutions for all these problems. The work gives analyses of ergonomics, hazards and safety techniques are related which develops a new framework to workers and safety is important with an ergonomics improvement of the workplace. The methodology classify and analyze the hazards in relation to physical, electrical and environmental parameters- as reported in the framework At conclusion of the study, the work reports data and insights from one manufacturing industry verifying different section with cases, which is relevant to industries.

In the last few decades, numerous of ergonomics risk assessment method was developed. These method was developed to prevent work-related musculoskeletal disorders or WMSDs among the workers. Although there is variety of methods was available to identify the present of WMSDs but the accuracy of the measurements is based on the methods applications and limitations. Due to the complexity of factors such as inhomogeneity of the working activities, the sophisticated of measurement process, the diversity of cultures, incapable to accesses various body posture, and others problem that remain unsolved, the evolution of ergonomics risk assessment methods was never ended. To react with the demanding related with the WMSDs problems, ergonomics risk assessment methods become more advance in technologies. Parallel with the upcoming challenges of industry revolution 4.0, ergonomics risk assessment methods need to be transformed and adapted with the advance technology-based methods. The industries already to step ahead and starting to represent their production activities using robotics technologies, artificial intelligence (AI), biotechnology, and super-computer technologies. Therefore, ergonomics committee and practitioner should realize the opportunities and developed new ergonomics risk assessment method that integrated with the technologies. They need to be more accessible, understood, visionary, and modernize. The evolution of ergonomics risk assessment methods must be continuing and not rely with the traditional approach only.

Abstract—Ergonomics is the study of the interaction between people and machines and the factors that affect the interaction. A number of factors play a significant role in ergonomics, and these factors determine the health, safety, comfort and efficient performance at workplace. Work-related musculoskeletal disorders (WMSDs) are the most common problems in manual work in small scale industries. The study presents assessment of working postures of workers from different small scale industries engaged in different activities. About 140 workers from 4 industries namely stone cutting & polishing, saw mills, brick making and dal mill are selected randomly. The study includes administering a musculoskeletal questionnaire to determine the level of MSDs among the workers. The workers are subjected to awkward postures like bending, twisting, heavy load carrying, etc. Evaluation of these postures was carried out using ergonomic assessment tools Rapid Upper Limb Assessment (RULA) and Rapid Entire Body Assessment (REBA). It can be concluded from the study that 32% of the postures adopted by workers are in high risk according to RULA and 36% are in high risk according to REBA assessment tools and need to be changed urgently. It is recommended to improve the working postures by ergonomic controls and interventions, and encourage the use of PPEs in order to improve the efficiency of the workers and overall productivity. Index Terms— Ergonomics, Postures, RULA, REBA, work-related musculoskeletal disorders.

CV Valasindo is furniture industry that produces a wide range of wood product. The production process in CV. Valasindo is devided in two areas, preparation of materials area and production area. This research is focused on work posture of the production area's workers. The production area itself consists of work stationssuch as assembly, construction and finishing. The production area was chosen because on the production process in this area is still done manually by the operator. Additionally, on the production area is also still present a series of no ergonomic work posture, both on the work station construction, assembly and finishing. The purpose of this research is to identify a work posture on the production area and doing an improvement to lowers the risk of musculoskeletal injuries. Based on the results of the assessment work posture against 18 work stations at the production area, the seat assembly work station it is known that has the highest risk of musculoskeletal injuries with a score of QEC 67. 9%, REBA 9, OWAS 3 as well as score NBM 75. Based on work by posture assessment method of QEC, REBA, OWAS and reinforced with method NBM then the improvement will be focused on work station assembly seat. In this study, the improvements done by designing a working facility in the form of tables and chairs work. Based on the results of the design work facilities have been simulated and the result is the risk of musculoskeletal injuries that used to be high risk decrease to be low risk.
Musculoskeletal Disorders, Workplace Ergonomics and Injury Prevention

Musculoskeletal Disorders (MSDs) affect body parts, with severity ranging from mild to intense. When MSDs develop in occupational settings, sequel to the physical tasks involved in the performance of work and the condition of the work-environment, they are referred to as work-related musculoskeletal disorders (WMSDs). The development and prognosis of any particular MSDs are modified by multiple risk factors, which are physical, individual, and psychosocial, in nature. None of these factors act separately to cause WMSDs, rather, they interact. The goal of ergonomics is to create an ergonomically sound work-environment, with the view to reducing the occurrence of WMSDs. This is premised on adherence to effective workplace ergonomic principles (WEP). By and large, WEP is more effective when done both at the workplace and during the performance of leisure time activities. Often, WEP involves designing the workplace, with consideration for the capabilities and limitations of the workers, thus promoting good musculoskeletal health, and improving performance and productivity. For favorable outcomes, a three-tier hierarchy of controls (Engineering, Administrative, and use of Personal Protective Equipment) is widely accepted as a standard intervention strategy for reducing, eliminating, or controlling workplace hazards. Failure of this strategy will expose workers to WMSDs.

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.
