Occupational Health and Safety - Prevention of Occupational Accidents

For zero occupational accidents

In 2024, Resonac reported 43 cases of leave-causing workplace accidents among employees and 13 cases among partner companies. This is almost the same number as in 2023.


In terms of accident types, falls, crush injuries, and lower back pain due to improper movements tended to be common both domestically and internationally. In response to this situation, we are promoting the following activities.

  • Interactive Safety Patrol (SCP): When a manager identifies unsafe acts or unsafe behaviors during patrols, they engage in dialogue with on-site employees, collaboratively consider the causes, and work on improvements to enhance safety levels.
  • Implementation of Risk Assessment: Conduct risk assessments related to occupational health and safety as well as chemical substances to reduce workplace safety and health risks and prevent accidents and disasters caused by chemicals. Analysis of Occurred Disasters and Recurrence Prevention: For occupational accidents that have occurred, deeply analyze their factors, investigate the root causes, and incorporate engineering analysis methods to advance essential safety measures. In addition to collecting, analyzing, and sharing information on lost-time and non-lost-time injuries, we also focus on gathering data on minor occupational accidents to prevent the recurrence of similar incidents.
  • Regarding the types of accidents that occur frequently, we conduct accident prevention activities at workplaces that serve as models for such initiatives, and we share the details of these activities within the group (TOPICS: Corporate Office Support Activities)
  • Review of Safety Education: Aiming to cultivate highly safety-conscious individuals, we strive to revise the safety education system and actively provide educational opportunities. 

TOPICSSafety Model Line Project Activities

In February 2024, we launched the "Safety Model Line Project" to aim for a workplace free of accidents and disasters, and have been carrying out activities. Specifically, in addition to efforts to prevent the most frequent types of labor accidents that occurred in 2023—namely "cuts and stabbings," "falls," "back pain during heavy lifting," and "accidents due to inadequate lockout/tagout procedures"—we have created model sites specializing in risk prediction training (KYT) and the development of trainers for the Safety Communication Program (SCP). These model sites serve as tangible examples for workplaces where activities can be observed firsthand, and these case studies are shared across domestic workplaces. In 2025, we will roll out these deliverables across the entire company to prevent labor accidents in advance.

TOPICSCorporate workplace support activities

From January 2025, in addition to KYT and SCP, we have started on-site corporate visits to conduct human resource education using the three basic safety tools, including mandatory safety training. Furthermore, we provide support such as improving working environments and safety measures for equipment, assisting workplaces in solving their issues. Additionally, for offices where many disasters have occurred (Special Safety Support Offices), we collaborate with those offices to support improvements in safety activities.

Collaboration with Partner Companies

  • Employees of partner companies who carry out work at the office are required to undergo safety education in advance. In addition, regarding environmental and safety management for partner companies, management regulations for partner companies have been established.
  • Holding Safety Meetings: To strengthen the safety activities of resident partner companies, information sharing, opinion exchange, and joint patrols are conducted at safety meetings. We continuously provide safety management guidance through environmental and safety audits of our partner companies. For contract construction workers who enter the site for a fixed period, we strive to ensure the completion of construction work as safely as possible by providing entry education, confirming work contents before the construction work, conducting patrols during construction, and holding safety meetings. Furthermore, risk management is implemented for each task entrusted to partner companies. In particular, high-risk tasks (such as those involving the use of fire or work at heights) are subject to prior review according to the rules established by the business site.

Operation of the Occupational Safety and Health Management System

At Resonac, each site has obtained certification for the "Occupational Safety and Health Management System" and appropriately reduces and manages risks related to occupational safety and health within the workplace. In addition, by continuously improving the management system, we aim to reduce the likelihood of occupational accidents and the associated business risks. This system undergoes regular maintenance and renewal audits by external certification bodies to ensure it is always up to date. In operational practice, we strive to revitalize activities by implementing the PDCA cycle (Plan-Do-Check-Act) throughout the entire workplace.

Safety and Health Audit

We have established evaluation criteria for the occupational safety and health management system, conduct self-assessments at each workplace annually, and carry out corporate audits. In fiscal year 2024, safety audits were conducted at 11 domestic workplaces and 19 workplaces overseas. In this audit, we were able to conduct on-site inspections from a broader perspective and document reviews through close information exchange. Moving forward, we will continue to conduct appropriate safety audits according to the purpose and situation and strive for continuous improvement.
