Occupational Health and Safety - Prevention of Occupational Accidents

Toward Zero Occupational Accidents

As one of the key quantitative indicators for occupational safety and health, Resonac continuously monitors the lost-time injury frequency rate (LTIFR). This indicator is calculated by dividing the number of lost-time injuries occurring during a specified period by the total working hours during the same period. The table below shows trends in the LTIFR and the number of lost-time injuries among domestic employees of the Resonac Group.

Fiscal Year Lost-Time Injury Frequency Rate Number of Lost-Time Injuries
2023 0.36 10
2024 0.64 18
2025 0.43 11

In 2025, the number of lost-time injuries decreased by 39% from 2024, with the LTIFR also decreasing by 0.21 points. We regard the continuous reduction of the LTIFR as one of the key indicators of business sustainability and management performance and aim to reduce the LTIFR to 0.1 by 2030.
Based on the same approach, we also monitor and analyze lost-time injuries at partner companies and work to prevent recurrence and improve safety standards.


In terms of accident types in 2025, caught-in or caught-between accidents and falls from heights were common in Japan, while slips, trips and falls and caught-in or caught-between accidents were common overseas. In response, we are promoting the following activities.

  • Publication of My safety declaration: The President, executives, and site leaders communicate safety messages in their own words, sharing company-wide the belief that protecting the safety and health of all colleagues is management's highest priority.
  • Safety Communication Program (SCP): When managers identify unsafe acts or unsafe conditions during patrols, they engage in dialogue with on-site employees, jointly consider the causes, and promote improvements to enhance safety levels.
  • Implementation of Risk Assessments: We conduct occupational safety and health risk assessments and chemical risk assessments to reduce workplace safety and health risks and prevent accidents and incidents involving chemical substances.
  • Analysis of Occupational Accidents and Prevention of Recurrence: We thoroughly analyze occupational accidents, investigate their root causes, and apply engineering analysis methods to implement fundamental safety measures. We also collect, analyze, and share information not only on lost-time and non-lost-time injuries but also on minor occupational accidents to prevent similar incidents from recurring.
  • For frequently occurring accident types, accident prevention activities are carried out at sites that serve as models for such activities, and details are shared across the Group (see "TOPICS: Safety Model Line Project Activities").
  • Review of Safety Education: We are reviewing our safety education system and proactively providing training opportunities to develop people with a high level of safety awareness.

TOPICSInitiatives to Establish a Safety Culture through the Safety Model Line Project

Since 2024, we have been promoting the Safety Model Line Project to create workplaces free from accidents and incidents. In addition to activities to prevent the most common types of occupational accidents, including cuts and punctures, slips and falls, lower back injuries caused by handling heavy objects, and accidents resulting from inadequate lockout/tagout procedures, we have designated as model lines the initiatives of sites specializing in KYT (Hazard Prediction Training) and the development of trainers for the Safety Communication Program (SCP), thereby creating sites where actual activities can be observed and sharing these examples across domestic sites. At these sites, we do more than simply establish rules. We share why situations are hazardous and what behaviors lead to safety, while managers and frontline leaders take the initiative in repeatedly engaging employees in dialogue to raise safety awareness. We also incorporate observations and opinions from the workplace into equipment improvements and revisions of work procedures, thereby maintaining and enhancing safe conditions. In 2025, we completed the establishment of these Safety Model Lines and began horizontally deploying the knowledge and practical examples obtained to other sites through site visits, exchanges of views, and information sharing on the internal portal site. Going forward, we will continue to use Safety Model Line activities to create a virtuous cycle of safety knowledge, awareness, and action and to embed a safety culture based on dialogue and mutual learning. We believe it is our responsibility to create a workplace where all colleagues proactively engage with safety and can work with peace of mind.

TOPICSAddressing Safety and Health Issues through Dialogue with Sites

To improve safety and health levels and embed a safety culture at each site, we worked on human resource development, safety guidance, and support for issues faced by sites. Rather than simply rolling out systems and rules, we emphasize listening to sites, sharing issues through dialogue with the workplace, and jointly considering solutions. In 2025, we conducted training at 12 domestic sites on fundamental safety tools, including KYT, SCP, duty-of-care safety training, and risk assessment, with a total of 896 employees and partner-company personnel participating. This helped build a foundation for managers, supervisors, and frontline leaders to share a common approach and independently think and act on safety. At the same time, headquarters personnel listened to the concerns experienced in daily operations through site visits and interviews, identifying safety and health issues common to multiple sites. Through repeated dialogue with sites, we prioritize these issues and jointly consider and support practical improvement measures based on direct observation of actual locations and conditions. In particular, for workplaces where safety issues have become apparent, we provide focused training and on-site support tailored to local circumstances.

Collaboration with Partner Companies

Before employees of partner companies begin working at our sites, we provide safety training in advance and ensure that basic safety principles and site rules are thoroughly understood and managed. For the environmental and safety management of partner companies, we have also established the Detailed Rules for Environmental and Safety Management of Partner Companies, clearly setting out our occupational safety and health policy and related guidelines, including those applicable to contractors.
To strengthen the safety activities of resident partner companies, we regularly share information on accident cases and points requiring attention for safe work and exchange views through safety councils, while also conducting joint patrols to verify workplace safety. We also conduct environmental and safety audits of partner companies and continuously provide safety management guidance. For construction workers entering our sites for a limited period, we ensure entry training and confirmation of work details before work begins, and strive for safer completion of construction through patrols during work and safety council meetings. Risk management is conducted for each task outsourced to a partner company. High-risk work, particularly hot work and work at heights, is subject to prior review under site rules. In this way, regardless of employment status, we make it a basic policy to protect the safety and health of all people at work and strive to create an environment where awareness of hazards and suggestions for improvement are voiced voluntarily through daily communication and dialogue.

Improving Safety and Health Levels through Environmental, Safety and Health Good Practice Activities

We collect and share outstanding environmental, safety and health initiatives at each site as Good Practices and work to improve safety and health levels across the Resonac Group. In selecting Good Practices, environmental and safety personnel and Senior Grand Masters who have a thorough understanding of workplace conditions and operational characteristics review the content and identify practical examples that can be applied at other sites. Selected examples are published on the internal portal site and used for learning across sites. Particularly outstanding initiatives are recognized through awards that celebrate workplace ingenuity and challenges. In this way, good activities are not confined to individual sites but are deployed across the Resonac Group, contributing to a safety culture in which sites learn from one another.

 

Occupational Safety and Health Audit Results and Enhanced System Effectiveness

To continuously improve environmental and safety management, we conduct environmental and safety audits at our sites. In 2025, audits were conducted at nine domestic sites and seven overseas sites. The audits confirmed that key environmental and safety management mechanisms, including environmental and safety risk management, management of change, and corrective action for nonconformities, had been established at each site. We also identified good practices, including improved access to environmental and safety information through the use of QR codes, innovative safety communication within sites, and the application of good practices such as measures for handling heavy objects and preventing slips, trips and falls through exchanges among sites.
From 2026 onward, we will focus on verifying the effectiveness of environmental and safety risk management and management of change, while strengthening direct support for workplaces, including headquarters-led environmental and safety training. We will also promote Group-wide sharing of good practices identified through audits and work to raise environmental and safety standards and improve effectiveness.
