Ergonomic Analysis Of Welding Operator Postures

Discomfort and pain are common in human-work activities and workers working in the industrial sector are easier to be exposed to the risk injuries. Occupational risk factors are the biggest entity causing health problems. Exposure to occupational hazards can adversely affect the human body, in turn reduce worker productivity and product/work quality and increase musculoskeletal problems. Observing the group of operators (welding) working throughout the day in the industry, which in turn helps in identifying the discomfort/pain experienced by the workers. The discomfort level of the workers can be evaluated by designing a detailed questionnaire and checklist to be present to the respondent. Ergonomic assessment tools like RULA (Rapid Upper Limb Assessment), REBA (Rapid Entire Body Assessment), OWAS (Ovaco Working Postural Analysis System) are used to assess the working postures and to analyze the discomfort frequency. Postures causing WMSD’s (Work-Related Musculoskeletal Disorders) are identified and recommending the guidelines to improve posture actions and to reduce the threat of WMSD’s.
