Safety and Prevention

The Mitsui Chemicals Group positions as KPIs and monitors major accidents, the number of abnormal conditions/accidents as well as the occupational injury frequency rate.

The Mitsui Chemicals Group is promoting initiatives for safe facilities and operations with the aim of achieving zero major accidents and zero serious occupational injuries.

In order to eliminate accidents and occupational injuries at the Mitsui Chemicals Group, we undertake initiatives at the Works and at domestic and overseas affiliates to entrench and thoroughly implement risk prediction and Pointing-and-Calling.
Risk prediction trainers are chosen at each Works to become drivers of these risk prediction initiatives, and company-wide meetings are held once a year to exchange opinions and share activities.
The Safety & Environment Technology Division provides training support on an ongoing basis for our affiliates. 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.

At each Mitsui Chemicals Group production site, information on workers’ narrowly avoided major accidents or disasters, or “near-misses,” that occur as a result of operations, is identified, and the details are shared within the organization. These sharing activities are ongoing. Specifically, in line with the occupational safety and health management system for each production site, the organization determines the cause of these near misses, as well as preventive measures. Relevant parties are provided with the lessons learned, and plans are put into effect that cover both concrete matters, as well as more intangible issues, in the course of operations. We then ensure that the necessary resources are still available to implement the preventive measures that we have formulated.

Our Works conducts small-group activities in which small groups of people work together to solve issues or matters such as enhancing production workplace capabilities, refining mindsets and human resources development, revitalizing the workplace, and improving the business, in consideration of the characteristics of a Works.
Through these initiatives, we are united in our efforts to improve the bottom line of plant revitalization. We also share the results of the small-group activities throughout a Works by means of presentations, and the honoring of best practices leads to heightened motivation.
We held a company-wide presentation of small-group activities in October of fiscal 2022. Connecting the Head Office, Mitsui Chemicals Works, and domestic subsidiaries and affiliates online, those who attended actively asked questions and made comments in response to the presentations from each site. We share the contents within the Group and promote the revitalization and improvement of workplaces and Works as a whole.

The Mitsui Chemicals Group introduces and maintains equipment that ensures safe and stable operation.

When introducing new facilities, we not only satisfy the relevant laws and regulations, but also design them in accordance with company rules based on our experience and accumulated technology, and introduce facilities that prevent accidents such as fires, leaks, and explosions through repeated change management based on various technical evaluations.

After an equipment is installed, we formulate maintenance plans and conduct periodic inspections and regular maintenance from the perspective of preventive maintenance.

In recent years, many of our facilities have been in operation for more than 40 years. While focusing on countermeasures against age-related deterioration, we have worked on developing appropriate maintenance plans, improving construction quality, and strengthening change management to maintain and improve the reliability and soundness of our facilities.

In addition, by actively adopting advanced technologies that are becoming practical due to recent technological advancements, we will seek to streamline and optimize our design, construction, and maintenance operations.

Furthermore, these efforts not only prevent accidents, but also contribute to environmental protection by reducing noise and odor and preventing leaks.
