In response to the impact of this economic crisis, many high-tech factories adopted flexible leave or layoff strategies to reduce operational burden. This study investigated the current status of human factors from three aspects, namely office workers, processing workers, and equipment maintenance workers. Instant assessment questionnaire on physical examination of musculoskeletal health was used to obtain the workers’ sensory data concerning human factors. In addition, the annual health examination was used to perform the physical examination on workers’ ergonomics to fully obtain relevant information on workers’ musculoskeletal hazards. This study further used the observation on on-site dynamic data, static data, and staff workload to confirm the workplace hazards to workers. For dynamic data, DV camera was used to photograph workers’ continuous movements, with a 30-minute film on every on-site worker. Moreover, digital camera was used to take the pictures of workers’ instant postures. For static data, a measuring tape and a weighing machine were used to measure of sizes and weights of machines and various cassettes. Heartbeat device was used to measure the workers’ workload. The analysis methods, such as OWAS for movement analysis, BRIEF checklist, 3D biomechanical model analysis, OSHA MSDs checklist, NIOSH’s composite lifting index analysis, and workload analysis, were used to collect the data on ergonomics at factories of high-tech industry. Moreover, the strategies of inherently safer design, such as intensification, substitution, software, and attenuation, were used to design and improve hardware equipment. A questionnaire survey was conducted to evaluate the improved results.
