Occupational Health and Safety

Working together, the Mitsui Chemicals Group conducts near miss activities, training in hazard prediction (kiken yochi, or “KY”), and the thorough implementation of risk assessments, while also engaging in activities aimed at preventing accidents and occupational injuries. The Group is committed to ongoing measures that help employees address a host of issues including lifestyle-related diseases and mental health.

Please refer here for details of the fire that broke out at the Mobara Branch Factory in July 2017.

Management System

Policy

Occupational Safety

Under our Responsible Care Policy, we pledge safety is our top priority and focus on achieving zero accidents and occupational injuries. We have also further formulated our basic items with regard to occupational safety, and promote occupational safety in line with Company regulations that cover environment and safety management.

Occupational Health

Under our Responsible Care Policy, we actively promote the well-being of all our employees, and in accordance with Company rules that pertain to environment and safety management, set forth in our basic items that also covers occupational health. We have also developed the basic philosophy of “Employee well-being is directly linked to the Company’s well-being.” Based on this, we work to develop occupational health measures, including for health management.

System and Responsible Officers

Occupational Safety

Assigning the president as the Chief and the director in charge of the Production & Technology Center as the person directly responsible, the Safety & Environment Technology Division formulates, disseminates and promotes the occupational safety strategy. In addition, they also collaborate with business sectors, production sites and affiliated companies to promote occupational safety.

Occupational Health

With the responsible director in charge of the Human Resources Division, industrial physicians from the parent company come together in regularly held physician conferences to consider issues and measures related to health management. Based on these conferences, we formulate occupational health plans during the fiscal year and proposals for annual plans, which are decided through deliberations by the Responsible Care Committee. In addition, the Head Office, Sodegaura Center, and the healthcare sections of all five of our Works take the lead in drawing up and expanding annual plans for each business site. Full-time industrial physicians, nurses, and health supervisors at healthcare sections support efforts to improve employee health. We also assign part-time industrial physicians, nurses, and other healthcare professionals to our smaller Works and to major Works operated by our subsidiaries and affiliates, in an effort to help improve the health of all Group employees.

Monitoring Methods

Occupational Safety

The Safety & Environment Technology Division regularly confirms, and ascertains the status of progress on key issues with regard to occupational safety at sites in Japan. In addition, information on occupational injuries throughout the Group is consolidated in the Safety & Environment Technology Division, and shared across the Group.

Occupational Health

With regard to Mitsui Chemicals business sites, we report the status of annual occupational health plan progress at industrial physician conferences, and aggregate as Companywide statistics the rate of findings of lifestyle-related disease risk, number of days off due to illness (and the degree of severity), number of days of mental health ailments (and the degree of this severity), and number of new cases of mental health disorders.
Furthermore, we conduct occupational health audits of Mitsui Chemicals business sites once every two years and at domestic and overseas affiliates once every three to four years while taking steps to achieve annual plans and make improvements in occupational health management-related problem areas.

Achievements and Reviews

Occupational Safety

We continued to be unable to achieve the world’s highest standard for safety which aims for a frequency rate of 0.15 or below with regard to Work-related Significant Occupational Injuries (WSOI). However, we are promoting preventive measures for similar types of incidents across the Group. In our 2025 Long-term Business Plan’s goals for environmental and social axes, namely, to pursue thorough safety, high quality, and fairness across the entire supply chain, we have positioned the important aspect of frequency of WSOI as a KPI, and we are clarifying our goal of achieving the highest global safety standards.

Work-related Significant Occupational Injuries (WSOI) :
  • Occupational accidents and injuries that are directly related to operations and result in days away from work cases or fatality
  • Restricted work or transfer to other job and medical treatment cases that are caused by a major incident and have the potential to result in fatality or days away from work cases

Occupational Health

Together with enhancing health as an important occupational health-related issue, there is a concern with an increase in the rate of lifestyle-related disease diagnosis. Looking at lifestyle-related disease risks, we see that there is a slight improvement in the blood pressure and blood sugar trends, but have positioned the trend toward greater rates of obesity as an important issue. In particular, we are working to expand measures targeting younger generations to prevent obesity. Mental health measures also represent important health issue for employees, and have an enormous impact on labor productivity. Utilizing stress check systems is a way we work to further raise the level of improvements in the workplace environment. With regard to the promotion of policies to prevent the release of chemical substances, we are seeking to reinforce measures in line with revisions to the Occupational Health and Safety Act, and we are moving forward methodically with particular attention to risk assessments with regard to the hazards of chemical substances.

Goals and Results

Goals for Fiscal 2016

Occupational Safety

  • Implement basic items on an even more comprehensive basis
  • Promote measures to prevent a reoccurrence of similar types of occupational injuries

Occupational Health

  • Enhancing employee and worksite health
    (1)Reduce risk of lifestyle-related diseases: Average rate of lifestyle-related disease diagnosis : Less than 9.0%
    (2)Reduce mental health disorders : Frequency of absences from work due to mental health disorders: Less than 0.35
  • Management of harmful substances in a forward-looking manner
    (Promote policies to prevent exposure to chemical substances)
    Risk assessment implementation rate : New substances being handled and SDS-updated substances 100%, implementation rate based on planning for other substances 100%

Fiscal 2016 Results and Assessments

Occupational Safety

Level achieved : C

  • Frequency rate of WSOI 0.23 (target : 0.15 or less).
    In total for the Mitsui Chemicals Group, goals for the frequency rate of WSOI were not achieved, having come in at 0.23 in fiscal 2016.

Occupational Health

Level achieved: C

  • Enhancing employee and worksite health
    (1)Average rate of lifestyle-related disease diagnosis: 9.7%
    Within the average rate of lifestyle disease diagnosis, the rate of obesity has increased, as has the average rate of diagnosis. From fiscal 2017 we will target young people with ample measures so that they do not become obese.

    New occurrences of mental health disorders have declined, but the frequency rate of missed work days due to mental health disorders has worsened as work absences have become more prolonged. In the future, together with the early detection of mental health disorders and thorough follow ups, we will endeavor to improve the workplace environment by utilizing stress check group analysis results and mental health climate surveys.
