Mitsui Chemicals

Occupational Health

The main purposes of occupational health are to prevent the health hazards caused by harmful factors in the workplace, while working to maintain and promote the health of employees. In addition to complying with the Occupational Health and Safety Act and related laws and regulations, the Company believes that encouraging employee health promotion leads to the happiness of employees and their families and that for employees to be energetically active in their local communities, including after retirement, is a corporate social responsibility and thus promotes occupational health. At the same time, the Company believes that healthy employees make for healthy organizations and contribute to an improvement in the Company’s labor productivity, and we are thus working to improve both the well-being of our employees and the organizational culture.

Management System


Under our Responsible Care Policy, we actively promote the well-being of all our employees.
In addition, under Company rules (occupational health regulations) that pertain to occupational health management, set forth in our basic items that also cover occupational health, we have 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

With the responsible director in charge of the Human Resources Division, the industrial physician who heads the Health Management Department (supervising industrial physician) in the Company’s head office holds regular Group-wide industrial 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 plan key issues and measures (Group-wide occupational health key issues), 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 occupational health annual plans for each business site. Full-time industrial physicians, nursing staff and health supervisors at healthcare sections promote efforts to improve employee health and measures designed to prevent employees from being exposed to harmful substances. We also assign part-time industrial physicians, nursing staff, 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.
The relevant persons and labor union members at each Mitsui Chemicals site hold a health and safety committee meeting for each site, in which they participate and at which they report on and discuss issues related to occupational health, including the maintenance and promotion of health, workplace environments and long working hours.

Monitoring Methods

With regard to Mitsui Chemicals business sites, we report the status of annual occupational health plan progress at industrial physician conferences and, to ascertain the risk of lifestyle-related disease, aggregate as Companywide statistics the detection rate, number of days off due to illness, number of days of mental health disorders, 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.

Review and Challenges

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, however, we see that there is an improvement in the blood pressure and blood sugar trends. In accordance with the increase in the obesity rate among young people, the overall number of obese people has been increasing, and I have positioned measures to combat obesity as an important issue. In particular, we are focusing on measures from young people. Mental health measures also represent an important health issue for employees and have an enormous impact on labor productivity. Utilizing stress level investigations is a way we will 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, risk assessment measures concerning hazardous materials and the reinforcement of measures are being sought in line with revisions to the Occupational Health and Safety Act. In fiscal 2018, we will look into developing risk assessments relating to the hazards posed by chemical substances from being absorbed through the skin.
