An open-ended questionnaire was administered to the participants of a six-part lecture series on self-controlled management of chemical substances regarding the support those participants would need when transitioning to that system, and the required elements of support were examined using a text-mining tool (KH Coder Ver. 3). The subjects were 59 persons who attended the lectures on an overview of self-controlled management of chemical substances and answered a questionnaire after the course. The lectures were organized by the Graduate School of Occupational Health, University of Occupational and Environmental Health from January-February 2022. The participants themselves indicated that they needed knowledge and up-to-date information on the revised law, as well as education about chemical substances. As for the support needed for individuals, the following were considered necessary: to provide support for education; management; information; the latest information; and education about the toxicity and dangers of chemical substances, which are necessary for education and chemical substance management in accordance with the revised law. As for the support needed for organizations, it was considered necessary to support the understanding of top management and the securing of necessary human resources.
