The amendment of the Occupational Safety and Health (OSH) Act which was made public in July 2013 specifies the adoption of an OSH consulting system to provide manufacturers with professional technical guidance. As far as the scope of professional technologies and the management of OSH consulting organizations are concerned, the ministry of labor has yet to formulate the relevant regulations. This study relies on data collection methods and in-depth expert interviews to collect relevant data on currently available OSH professional manpower in Taiwan, as well as the training of professional personnel in major foreign countries, the accreditation and service management system, and the viewpoints of representatives of OSH related industries, government agencies, and academic circles in Taiwan. This study provides a summary of the abovementioned results as a reference for professionals in related fields. The author discovered that the US is characterized by the highest manpower density in the field of OSH with around 219 professionals per 1 million workers. This is followed by Japan with 146 labor safety and health consultants per 1 million workers, and the UK with 73 registered consultants per 1 million workers. It is 77 qualified OSH engineers for 1 million workers in Taiwan. If calculations are solely based on the number of practical engineers or health engineers who conduct work environment surveys, the ratio drops to less than 9 engineers for 1 million workers. Professional OSH technologies include environmental engineering control, process and construction risk assessment, health risk and exposure assessment, guidance for the prevention of occupational diseases as well as man-machine interfaces. It is recommended that engineering technicians of related fields, occupational medicine physicians, and research personnel of colleges and universities should also be commissioned to provide different types of technical services. It is further suggested that the eligibility criteria for OSH engineer exams be widened to allow professional personnel in the fields of science, engineering, and medicine to provide professional safety and health services on a concurrent basis to fill the manpower gap in this field.
