Safety and Prevention

The Mitsui Chemicals Group is implementing various initiatives, including training and drills, toward nurturing human resources with a high awareness of dangerous situations and the ingraining of a safety culture throughout the Group.

Mitsui Chemicals’ Ichihara Works, Osaka Works, Iwakuni-Ohtake Works, and Omuta Works are equipped with self-defense firefighting units. The unit members are regularly trained in preparation for an emergency.

In recognition of the results of daily training, the Iwakuni-Ohtake Works and Osaka Works received the Encouragement Award in the "Skills Contest for Self-Defense and Disaster Prevention Organizations at Petroleum Industrial Complexes" held in fiscal 2025 by the Fire Defense Agency, Ministry of Internal Affairs and Communications. This skills contest has been held since fiscal 2014 to inspire self-defense firefighters, as well as motivating them to continue to improve their skills. The participants complete safety, reliability, and promptness of their performance by conducting a procedure of releasing foam water from a height onto a simulated fire at a hazardous facilities. This marks our 12th consecutive year to receive an award since the contest began. We continue improving our firefighting skills through determined training to contribute to the safe and stable operations of our Works.

To eliminate accidents and occupational injuries, the Mitsui Chemicals Group continues to provide hazard prediction　 training at each of its Works based on the belief that it is important to develop human resources capable of recognizing hazards as dangers and taking appropriate safety actions to prevent them.

In addition, with regard to risk prediction and Pointing-and-Calling training for domestic and overseas affiliates, the Safety & Environment Technology Division provides training support on an ongoing basis. Through this support, we are working to ensure that all of our affiliates understand the significance and necessity of risk prediction activities and Pointing-and-Calling so that they can use and entrench them in their actual work situations. The training is also held online and incorporates exercises, presentations, and team discussions that are appropriate to actual work situations. It looks back on their daily tasks and raises awareness so that safer actions can be taken. Key men are necessity to entrench risk prediction and Pointing-and-Calling, and the Company is encouraging their development through training.

Mitsui Chemicals is actively engaged in various measures to foster engineers with specialized knowledge, technology, and skills, as well as to steadily pass on technology to the next generation, as part of its human resource development system based on the personnel system.
Specifically, the systematic passing of technology and development of human resources are stipulated in job descriptions and job classification tables for skilled employees, and the system clarifies the passing of technology as part of the job and holds employees accountable for their efforts.
In addition, we have defined our development plan up to the point where they assume key roles in Works under the “Production Engineering Human Resource Development Plan” to clarify the abilities and skills required to carry out their respective duties. We have also established an education system and the curriculum necessary for acquiring these abilities and skills as an “Annual Education Plan,” and provide step-by-step education through company-wide and plant collective education, e-learning, and various other off-the-job training programs, as well as through rotations and on-the-job training.
In our training, we place particular emphasis on problem-solving and accident case study education. Through factor analyses and accident case study discussions based on actual trouble cases that have occurred at production sites, we cultivate the sensitivity to identify potential sources of danger.
