Chemical Safety Education in Academic Laboratories

Chemical safety education in academic laboratories has evolved into a multi-faceted discipline that underpins both the pedagogical mission and the research enterprise of higher education. Modern programmes integrate theoretical instruction on hazard classification, regulatory frameworks and safety culture with practical exercises in risk assessment, accident investigation and emergency response. Central to this evolution is the adoption of structured models—such as the SHEL (Software, Hardware, Environment, Liveware) framework—and quality-management principles adapted from industrial settings, including HACCP (Hazard Analysis and Critical Control Points). Digital tools and cloud-based platforms are increasingly employed to deliver real-time training, track individual competence and support dynamic risk assessment. Emphasis on experiential learning encourages students and early-career researchers to participate in mock drills, peer-led workshops and scenario-based simulations. Safety culture is nurtured through regular safety audits, visible leadership commitment and mechanisms for reporting near misses without fear of reprisal. Interdisciplinary collaboration with information science, occupational health and environmental stewardship underlines the global significance of robust chemical safety education. By embedding safety literacy within laboratory curricula, institutions not only reduce the incidence of accidents but also foster responsible citizenship, environmental protection and sustainable research practices.

Research from Nature Portfolio

Recent studies have applied a systems-based analysis to laboratory explosions at universities, classifying incident reports through a SHEL framework to identify recurring contributory factors. This work has culminated in a standardised methodology for accident investigation that can be shared internationally, enabling the comparison of data across institutions. By mapping software, hardware, environmental and human elements contributing to chemical incidents, this approach provides a foundation for harmonised reporting rules and preventative guidelines, fostering collective learning and targeted interventions to avert future accidents.

Chemical Safety Education in Academic Laboratories publication trend

The graph below shows the total number of articles in chemical safety education in academic laboratories across all publications each year (not limited to Nature Index journals).

Technical terms

SHEL model: A conceptual framework for analysing laboratory accidents by categorising contributing factors into software, hardware, environment and liveware elements.

HACCP (Hazard Analysis and Critical Control Points): A systematic preventive approach originally developed for food safety, adapted to identify and control hazards in chemical laboratories.

Risk assessment: The process of identifying, evaluating and prioritising hazards to determine appropriate control measures and reduce potential harm.

Safety culture: The collective values, attitudes and behaviours that shape how safety is prioritised, communicated and maintained within an organisation.

System dynamics (SD): A computational modelling method used to simulate the interactions among factors influencing laboratory safety over time, often coupled with structural equation modelling for parameter estimation.
