Abstract
In Japan, work environment measurement has been carried out based on work environment measurement standards to the management of harmful substance exposure to workers. But nowadays, the promotion of risk assessment and personal sampling methods are applied to work environment measurement standards, the importance of assessing the working environment by measuring personal exposure is increasing. Particularly in research institutes such as universities, where a large number of chemical substances are used in small quantities and the distribution of hazardous materials changes markedly over the course of a day, it is considered difficult to accurately grasp the exposure situation using conventional working environment measurements. A photoionization detector (PID), sensitive and capable of detecting a wide variety of chemical substances, have been developed and are being applied as instruments for monitoring personal exposure to organic solvents. In this study, personal sampling methods using a PID personal exposure monitor and a passive sampler were carried out, and the results were compared with the results of conventional work environment measurements. In addition, the results of real-time monitoring using a PID personal exposure monitor were used to identify the exposed work, and the effectiveness of work management was examined based on the maximum exposure concentration and exposed work. Furthermore, we conducted safety and health training using these results and conducted a questionnaire survey on safety awareness before and after the training, and as a result, we were able to confirm changes in awareness of exposure conditions.
