Abstract

Object:

Improper workplace design is one of the significant reasons for occupational accidents and injuries in labor-intensive production sites. Inadequate and incomplete working environments ignoring ergonomic factors at the planning level create persistent psychical disorders, increase mistakes and accident rates and decrease work productivity. Enhancement of the compliance between worker and task is a crucial step for improving productivity.

Method:

The worker can reach increased productivity with less physical load and less energy consumption when compliance is accomplished. This study has been implemented in a medium sized labor-intensive furniture factory located in Denizli, Turkey. In this study, physical workload of operators is the loading and unloadingby machinery in solid wood processing workshop of the factory. Initially, the working environment of this division is investigated ergonomically and then 12 of the machines are selected for implementation. Individual characteristics, working conditions and postures of the operators in the selected machines are determined by using surveys, measurements and video recording techniques. After analyzing loading and unloading operations of workers, operation times and posture frequencies are determined. Ovako Working Posture Analysis System (OWAS) is used to find the workloads and potential risk of work-related musculoskeletal disorders.

Result:

The results show that inadequate and incomplete working environment and operational designs are the main reasons for the high workload level and serious physical disorders among the workers. Operational design improvements related to working environment are presented to the senior management of the factory that may help decrease the risks of work-related musculoskeletal disorder in the workers.

Keywords: Furniture industry workers, Work-related musculoskeletal disorders, Risk assessment, OWAS method, M10 machine.

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."


Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."


Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."


Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."

"Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content."


Sean L. Kitson
(Almac Sciences, Northern Ireland)

"In principle, all scientific journals should have open access, as should be science itself. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals. The articles are high standard and cover a wide area."
