زمینه و هدف

Manual handling is one of the most detrimental tasks in agricultural occupations, which may lead to many musculoskeletal disorders. Musculoskeletal disorders in many agriculture workers caused disability, unsatisfactory, and losing time. In addition, it may be a factor that will result in the production cost. This study aimed to investigate the factors affecting safety while performing manual handling tasks in the manual handling of agricultural products using systems thinking.

روش کار

A multi-method approach, including observation of manual activities and interviews with farmers, was used to collect data on potential risk factors for musculoskeletal disorders. Two common tasks of manual handling of agricultural products were observed by the ergonomics expert. 15 minutes of each task were recorded by 10 agricultural workers. One work cycle of each activity was selected for data extraction. Also, semi-structured interviews were conducted with 10 farmers who performed these tasks. The interviews were recorded using a recorder and then written in Microsoft Word software. Interviews were coded using the thematic analysis approach and MAXQDA software. Finally, the information extracted from the observations and interviews was presented in Rasmussen's AcciMap framework to show the effective factors in causing musculoskeletal disorders during the manual handling of agricultural products.

یافته‌ها

The risks identified from the interviews and observations were summarized in a 5-part framework including government and regulatory, agricultural Jahad of provinces, families and villagers, staff and work, and the relationship between the risks was determined. The most identified risks were at the level of staff and work. At the government and regulatory level, there were issues such as the lack of a specific law and the lack of support for agricultural unions. At the level of provincial agricultural Jahad, there were also issues such as lack of education, weak financial support, etc. At the level of the family and the villagers, there were issues such as work and family imbalance, insufficient support, etc. At the level of staff, fatigue, unsafe practices, lack of use of equipment, etc. were placed. Finally and at the lower level, time pressure, inadequate and inappropriate equipment, asymmetric loads, long distance of manual load carrying, etc. were placed.

نتیجه‌گیری

The findings showed how an approach based on systems theory can be applied in the field of agriculture, and it is suggested to adopt a general and systemic view to prevent injuries in agricultural activities instead of a partial view of the worker and the task. In the general view should concentrate on appropriate legislation and supports in education, financial grants, and enhancing tools that are used by farmers and improving their job satisfaction.
