A new safety education system involving the memory mechanism

Safety education on liquid cryogen for Kagawa University Faculty of Engineering and Design consisted only of a single class that combines lecture and practice using presentation slides and printed materials that lead to understanding. However, investigation of the causes of liquid seal-related incidents that occurred in engineering departments strongly suggests that current safety education does not adequately prepare students to handle an actual crisis.This paper presents safety education programs in engineering departments focused on the mechanism of human memory to enable students to avoid adverse incidents by fully acknowledging the danger of the task of pumping liquid nitrogen. Firstly, we conducted a safety training that consisted of a lecture using interactive teaching materials and practical training utilizing video. Then, we carried out distributed learning to memorize these contents. Thereafter, through data via IC certification and work monitoring, issues were confirmed and then applied to create supplementary relearning materials for groups classified as having low education effect. Furthermore, a task-assistance web application was introduced that eliminates factors that hinder information communication based on operator attributes.This system drives educational content into long-term memory and is expected to be used in fields other than education on liquid nitrogen as a safety education model that encompasses a system that can retrieve this memory.
