Safety and ergonomics evaluation of hybrid systems in Hong Kong

This study is aimed at understanding common safety and ergonomics problems with robot installation in Hong Kong. Information was collected through direct observations and personal interviews with robot users from advanced hybrid manufacturing systems. The application areas of robots and types of safety devices employed were investigated. The ages, types of jobs, daily working hours and working conditions of personnel were examined. Fire precaution measures, types and varieties of training programs for users were analyzed. The results showed that although investments were made for installation of robots for improving production activity, limited attention was paid to the health, safety, and ergonomics aspects in the hybrid systems. There were also cases reported where no formal guidelines for robot manipulation and operation were provided. It seems that management and users paid attention to robot function and capability more than robot safety during robotization process. Conclusions were made by the authors that efforts should immediately be made to adopt recommendations on the safety devices and facilities and training requirements for improving users' health and safety before fatal accidents occur.
