Ergonomic hazards among rag pickers in India: an analytical study

Abstract

The aim of the study was to identify the work-related ergonomic hazards experienced by the rag pickers. Multi-stage random sampling technique was used for selecting the sample. Tools used to conduct the study comprised of general information, rating scale for assessing intensity of discomfort, and Nordic Musculoskeletal Questionnaire. The statistical analysis of the quantitative variables was performed using SPSS software program, v20.0. Research revealed that rag pickers experienced severe pain in lower back (65%), followed by upper back (52.5%), feet (47%), and hands (43%). Older rag pickers, between 55 and 65 age groups, reported more discomfort or pain in backache and knee (µ = 2.00), as compared to other age groups. This may be due to the reason that with age, bones become weak and the strength of the muscles also reduces, and since they are involved in the work. Rag pickers experience many work-related ergonomic problems, and these problems are associated with various risk factors such as working experiences and age. Frequent bending, standing, and carrying heavy loads on the back increased these problems. To lighten the load of ergonomic problems, preventive and curative approaches are strongly suggested. Ergonomics and safe practices must also be established to reduce work-related vulnerabilities.
