Summary
Investigating industrial accidents requires understanding analyst-identified causes, not just actual ones. Simulated investigations offer a realistic method to study and improve safety analysis, bias detection, and training.
Area of Science:
- Safety Science
- Human Factors Engineering
- Cognitive Psychology
Background:
- Industrial accident investigations are critical for safety management, but their effectiveness hinges on the causes identified by analysts.
- Previous research on investigation bias was limited by its artificiality, not mirroring real-world tasks involving information acquisition, analysis, and interpretation.
- A gap exists in understanding how investigators acquire and interpret information, and how this impacts safety management strategies.
Purpose of the Study:
- To develop and validate a novel technique using simulated investigations to overcome limitations of previous studies on accident causation and bias.
- To compare elicited knowledge and hypotheses among safety specialists using simulated investigations.
- To evaluate the effectiveness of job aids in improving accident investigations compared to unaided methods and to assess their utility in training.
Main Methods:
- Development of a simulated investigation technique that mimics real-world accident analysis tasks, including information gathering and interpretation.
- Three studies were conducted using this simulation: comparing safety specialists' knowledge, assessing job aid effectiveness, and evaluating training potential.
- Participant acceptance and flexibility of the simulation method were assessed.
Main Results:
- The simulated investigation technique was well-accepted by participants, demonstrating its practicality for research and training.
- The method allows for the comparison of elicited knowledge and hypotheses among different groups, such as safety specialists and students.
- The simulation provides a flexible platform for exploring investigation bias and comprehensiveness, with potential applications in educational settings.
Conclusions:
- Simulated investigations provide a valuable and realistic method for studying the complexities of industrial accident analysis and improving safety management.
- This technique offers a flexible tool for research, training, and evaluating interventions like job aids to mitigate investigation bias.
- Further research may explore the limitations and expand the applications of simulated investigations across various industrial safety contexts.
