At-risk behaviour analysis and improvement study in an academic laboratory

摘要

Academic laboratories contain inherently substantial risk conditions that students could expose to chemical and physical hazards. Procedures and guidelines related to laboratory safety are commonly available for students to adhere. However, many injuries and accidents or even fatalities are reported due to students' violated safety practices while working in the laboratory. There was no reported proactive method or systematic technique to monitor and control students' at-risk behaviour in the laboratory. This paper presented a program known as laboratory at-risk behaviour and improvement system (Lab-ARBAIS) to monitor and control students' at-risk behaviours in the laboratory. Lab-ARBAIS used computer database for data acquisition and analysis on students' at-risk behaviours observed. Pre-program questions on students' at-risk behaviours that frequently violated safety regulations were utilized by observers to give observation feedback. The collected feedback was analysed and the results were posted in students' portal to allow everyone to acknowledge their safety habits and practices. The routine observations and posted results are to instill a psychology effect in student's habitual safety practices by reminding them on their frequently violated safety regulations. The implementation of the Lab-ARBAIS program to chemical engineering laboratory as a case study had shown a significant improvement on students' frequent at-risk behaviours. The Lab-ARBAIS can easily be adopted in any academic laboratories to manage students' at-risk behaviours to ensure safe work environment. With minor enhancement, the Lab-ARBAIS can easily be extended to be used in industrial laboratories.
