Higher education chemical lab safety interventions: Efficacious or ineffective?

In this paper, we first derive a model from literature providing insights into the influence of different aspects of safety on each other, that is, knowledge, perception, attitude, behavior and its consequences. We called it the “KPABC model”. An experiment was furthermore designed and carried out to investigate the impact of laboratory safety interventions with students, and on the different safety aspects of the KPABC model. We finally explain the research results, and based on the findings, we provide recommendations on how to improve safety within higher education chemical labs.
