Indoor air pollution by chemicals should be paid more attentions in relation to its adverse effects not only on human health but also on productivity of workers or learners. In educational courses of university where many chemicals are used in practical subjects of chemistry, risk management of such chemicals is a basic demand to build up comfort learning environment. In this study, authors have conducted a case study on a continuous monitoring of indoor air concentrations of total volatile organic compounds (TVOC) in classrooms using a TVOC sensor. The TVOC concentrations were monitored at 2-min interval during the classes of Analytical Chemistry Practice, Organic Chemistry Practice and a lecture on Quality Management. The results showed ventilation fans were not properly operated in the classroom of practice, even when the TVOC concentrations remarkably increased. This was because the fans were operated by a subjective judgment of the instructors. We proposed use of the TVOC sensor in classrooms to alert a level of pollution and control ventilation system in automatic ways for the purpose of preventing undesired effects by chemicals.
