The purpose of this study is to adopt the safety climate into domestic construction site effectively, in addition conduct the survey for the awareness of safety climate and analyze the Musculoskeletal Disorders (MSD) of manual material handling (MMH) workers who work in army construction site and Directorate of Public Works (DPW) facilities under United States Forces Korea (USFK) camps in Korea. Job tasks in the construction trades often involve materials handling activities such as lifting, carrying, and removing, workers are at risk for musculoskeletal disorders from both acute and repetitive stress. This is especially evident with work that involves heavy materials and strenuous physical activity. The survey contained three sections. The first section consisted of ten questions with type of trade, years in trade, yearly working time, working status, handedness, gender, age, height and weight. The second section of the survey was a modification of the standardized KOSHA MSD questionnaire. The third section of the questionnaire concerned the workers’ perceptions of the physically stressful elements in their job. This portion of the questionnaire contained a listing of fifteen conditions and tasks with the following instructions, this list describes things at work that could contribute to job-related pain and injury. This study determines the factor structure of safety climate within an army facilities construction site using a modified version of the safety climate questionnaire (SCQ). It also investigates the relationship between safety climate and MSD. The SCQ was administered to 628 employees from four (4) areas (Uijongbu, Yongsan, Pyongtaek, and Daegu) and in three (3) job categories – construction, maintenance, and office work. Factor analysis derived four (4) factors, which were similar to those obtained in an earlier study using the SCQ. No differences between the earlier study and current domestic survey were found. Discussion focuses upon the measurement of safety climate, and also requires studying relationship between safety climate and job stress on behalf of MSD.
