Virtual reality for safety training: A systematic literature review and meta-analysis

Unsafe behaviour in the workplace and disaster events can lead to serious harm and damage. Safety training has been a widely studied topic over the past two decades. Its primary aim is to save lives and minimise damage but requires regular refreshers. New digital technologies are helping in the process of enhancing safety training for better knowledge acquisition and retention. Among them, Virtual Reality (VR) can provide an engaging and exciting training experience, and there is a need to evaluate its application and effectiveness in safety training.This study aims to investigate VR safety training solutions applied to various industries (excluding medical and military applications), such as construction, fire, aviation, and mining. This was achieved by systematically reviewing 52 articles published between 2013 and 2021 to answer nine research questions. Fourteen domains were examined, with construction and fire safety training being the most prevalent since 2018. Findings reveal that only a small percentage (9.6 %) of the studies explicitly adopted theories while developing and testing VR applications. Additionally, this review highlights a critical need for long-term retention measurements, as only 36 % of studies provided such data. Finally, the two meta-analyses proposed in this work demonstrate that VR safety training outperforms traditional training in terms of knowledge acquisition and retention.
