How effective is virtual reality for electrical safety training? Evaluating trainees' reactions, learning, and training duration.

Introduction: The widespread use and inherent risks associated with low-voltage electrical equipment require all workers to understand its hazards and how to manage them. Despite being the most commonly used method for raising safety awareness, lecture-based training often proves ineffective. Virtual reality (VR) allows the user to be immersed in a virtual environment and actively participate in practical training while maintaining their safety, which can potentially result in engaging and effective training. This paper investigates the effectiveness of using immersive VR for low-voltage (LV) electrical safety training to understand the potential benefits of VR technology for industrial safety training applications.

Method: A within-group experimental design was employed with 18 participants undertaking the LV VR training. The effectiveness of the training was evaluated by measuring participants' reactions, learning, and training duration. Participants' learning was measured before, immediately after, and four weeks after the training, whereas reaction and suitability of training duration were measured after the training.

Results: Participants reported highly positive reactions to the LV VR training, particularly regarding their level of engagement, intention to use the system in the future, and enjoyment. Knowledge test scores significantly improved immediately after training with high effect sizes. Although scores decreased significantly four weeks after training, they remained significantly higher compared to before training. The training duration, ranging from 29 to 44 minutes was considered suitable for the training.

Conclusions: LV VR training effectively elicited positive reactions from trainees and supporting trainees to acquire and retain safety information while maintaining appropriate training duration.

Practical Implications: VR emerges as a viable alternative training method worth exploring for organizations seeking to improve their safety training programs. VR combines educational and entertainment values, facilitating enjoyable learning experiences.
