Tokyo, October 7, 2025 Hitachi, Ltd. (TSE:6501, "Hitachi") and Hitachi Plant Construction, Ltd. ("Hitachi Plant Construction") have developed a new risk and hazard prediction*1 support system designed to enhance worksite safety using the next-generation AI agent "Frontline Coordinator – Naivy" ("Naivy")*2 to help forecast hazards. The system, a specific use case of Hitachi’s Advanced On-Site Safety Solution,*3 increases the comprehensiveness and immediacy of information, the lack of which has been an issue with traditional hazard prediction training using paper or whiteboards. The system realistically recreates the worksite in the metaverse, and Naivy, the core component, instantly analyzes and retrieves similar past cases. In addition to verifying safety procedures and rendering hazardous locations visually, the system also presents visualizations of potential risks and optimal safety precautions for each site in a way that is intuitive for workers. It thus creates an environment where workers can proactively identify risks specific to their worksite and formulate effective countermeasures. Hitachi Plant Construction has conducted multiple pilot tests on this system at a client’s substation. These tests found that the system enhanced workers’ safety awareness while reducing the time required for hazard prediction training by approximately 20 percent, thus ensuring safety without sacrificing efficiency.
Going forward, Hitachi and Hitachi Plant Construction will further evolve Naivy by drawing on our knowledge and expertise in improving workplace safety as well as the new domain knowledge gained through collaboration between workers and Naivy. While promoting the use of on-site domain knowledge, we will deploy Naivy across industrial sectors such as construction, electric power, railways, manufacturing, and maintenance as part of the suite of applications that embody Lumada 3.0. This will contribute to enhancing frontline workers’ efficiency and well-being and creating a safe workplace for everyone.
Some of the project outcomes will be on display at CEATEC 2025 at Makuhari Messe in Chiba, Chiba Prefecture, from October 14 to 17, 2025.
*1 risk and hazard prediction: It refers to reducing the risk of occupational hazards and preventing accidents by identifying in advance unsafe conditions, behaviors, and mental states lurking in the workplace. It also embraces wider evaluation of risks, incorporating elements of risk assessment.
