Further improvement of worksite safety through AI-powered risk prediction app

Mitsubishi Electric Building Solutions Co., Ltd. (President & CEO: Iwao Oda, Headquarters: Chiyoda-ku, Tokyo) has developed an AI-powered application called "KY-Support" to support "Risk Prediction Activities" (hereinafter referred to as KY activities) with the aim of preventing labor accidents at worksites for elevators and escalators. The company will sequentially introduce it company-wide starting from April 2026.

In recent years, the prevention of labor accidents has become a top management priority. Based on the policy of "Safety and Quality First," the company is pursuing on-site safety management aimed at zero serious accidents and is also strengthening initiatives to prevent minor accidents and recurring incidents.

KY activities are safety initiatives that prevent labor accidents by predicting potential hazards before work begins and having all workers share countermeasures and action goals. While the company conducts KY activities at all site operations, there are challenges such as younger and less experienced workers having difficulty noticing potential risks, and ensuring that KY activities do not become a mere formality for experienced veterans.

With the goal of establishing a system that allows anyone to conduct high-quality KY activities, the company has developed and will introduce an application equipped with AI that utilizes various work data and past labor accident examples, rather than relying on individual experience and knowledge. This will help prevent labor accidents through advanced KY activities.

"KY-Support" is an application built based on the "On-site Work Support Technology Utilizing Generative AI" announced by Mitsubishi Electric Corporation on January 14, 2025, in strategic collaboration with Amazon Web Services (AWS). This is the company's first full-scale operational application of AI. By using AWS's AI platform "Amazon Bedrock," it leverages vast work manuals and past accident examples as "awareness and advice for safe work."

Mitsubishi Electric Building Solutions will continue to promote the provision of safe, secure, and comfortable building spaces through the proactive use of digital technologies.

Features of "KY-Support"

1. AI identifies work risks, supporting junior education and reconfirmation by veteran workers

Based on accumulated work data, the AI presents potential risks specific to the work, and also provides real-time advice on the action goals that workers consider for the work site. It compensates for the lack of knowledge in younger workers and serves as an opportunity for veteran workers to reconfirm, thus preventing KY activities from becoming a mere formality.

2. Smartphone-optimized design for smooth on-site operation

The application prioritizes on-site mobility and is specialized for smartphone use. It is optimized for one-handed operation, such as using voice input and intuitive tap-centric controls, allowing for easy implementation and recording of KY activities.

3. Ensures safety confirmation through a process compliant with the Basic 4 Rounds Method of KYT (4R-KYT)

The application reproduces the steps of the "4 Rounds Method (Current Situation Assessment, Root Cause Analysis, Countermeasure Establishment, Goal Setting)," which is the basic method of KY activities. By following the on-screen guidance, users can reliably perform steps without omission, enabling standardized, high-quality safety confirmation for everyone from beginners to veterans.
