A model of ergonomics intervention in industry: case study in Japan.
This paper presents the results of an ergonomics survey in four different Japanese work places. The survey consisted of two parts. In the first part, the physical and psycho-social problems of the female workers were investigated. Questionnaire techniques were used to assess musculoskeletal disorders in various parts of the body and of psycho-social stress at work as well as in the daily life situation. Furthermore, work posture analysis, task analysis, simple clinical tests and flexibility tests were conducted. In the second part, the ergonomics intervention practices in different types of Japanese work places were examined. Three different questionnaires were developed and used to collect information from representatives of employees, management and responsible governmental agents of the Department of Industrial Safety and Health, Ministry of Labor, with regard to ergonomic interventions at work places. Management, employees, and government representatives expressed desire for cooperation and participation for arrangement of the ergonomics intervention program. A model for appropriate ergonomics intervention in industry is developed with regard to physical and psycho-social problems at work. Factors influencing worker participation and the establishment of a dynamic system of ergonomics intervention at work places are discussed. Practical ways for improving the working conditions of female workers are: (i) cooperation between managers, workers, and government officers is regarded as vital for the ergonomics intervention program, (ii) worker participation, (iii) appropriate training course with regard to ergonomics education, and (iv) managerial support.
