Occupational Safety and Health

Initiatives for the occupational health and safety of employees

Policy for occupational health and safety

The management of occupational health and safety is the base of corporate activities, so enterprises cannot conduct business activities without securing and managing occupational health and safety. S.T. CORPORATION and group companies (hereinafter collectively called “our corporate group”) implement the initiatives for managing occupational health and safety and bring comfort and richness to the daily lives of people by utilizing our unique Air Care core technologies. Our corporate group recognizes the importance of management of occupational health and safety well and promote the management of occupational health and safety in cooperation with all stakeholders.

This policy applies to our corporate group. Our corporate group expects and promotes business partners and all other stakeholders to manage occupational health and safety in accordance with this policy. In order to do so, the chairperson of the Group-Wide Occupational Health and Safety Committee, which manages occupational health and safety, controls related activities and implements continuous initiatives.
While observing laws, regulations, etc., we formulate our own standards, including rules, if necessary, to manage occupational health and safety.
We will make the utmost effort to maintain a working environment where employees can work safety without worry and prevent industrial accidents.
1. We regularly assess risks, to remove latent risk factors. In addition, we promote the reporting of near-miss cases, to prevent accidents thoroughly.
2. We thoroughly inspect and maintain machinery and equipment at manufacturing facilities, and strive to improve the working environment (by organizing, tidying up, cleaning and items, keeping them clean, and disciplining workers).
3. We conduct regular health checkups and follow-up activities, to support the maintenance of employees’ health.
4. We implement measures for preventing overwork and maintaining good mental health, to develop comfortable workplaces.
5. To respond to emergencies, we produced manuals for dealing with disasters and accidents and conduct disaster drills. We are also cementing the cooperation with related institutions, to make it possible to swiftly respond to emergencies.
We offer necessary education and training to employees to enhance their awareness of occupational health and safety and promote activities for managing occupational health and safety.
While proactively disclosing information, we communicate with customers, shareholders, business partners, local communities, and others, and promote activities for managing occupational health and safety in cooperation with them, to pursue such activities and proceed with co-creation.
While clarifying our roles, authority, and responsibilities for managing occupational health and safety, we have the Group-Wide Occupational Health and Safety Committee for occupational health and safety set goals and plans, execute them, evaluate performance regularly, and allocate managerial resources appropriately, to keep improving the management of occupational health and safety.

Initiatives for the occupational safety of employees

Based on the belief that occupational health and safety management is the foundation of corporate activities and that business activities cannot be carried out without ensuring and managing that, the Group will promote occupational health and safety management while cooperating with all stakeholders.
We will formulate an occupational health and safety policy, construct a company-wide occupational health and safety management program and an occupational health and safety management system, and continue to implement these measures.
Each plant is working to maintain safe operations and a safe environment by establishing management items related to health and safety, and disaster prevention; implementing self-inspections; and improving instructions and manuals. At the “STR-MP” meetings, which are attended by production sites in Japan and Thailand, opinions are exchanged on occupational health and safety, and these opinions are reflected in occupational health and safety activities at each plant. At our own plants in Japan and Thailand, and at major domestic outsourced plants, personnel from the head office conduct periodic safety management inspections to check the status of safety and health management systems and operations. At the Thailand plant, where it is difficult for the personnel at the head office to conduct a direct inspection, a company-wide risk assessment is conducted using a web conference system.
Furthermore, we have created a manual for the initial response to a crisis, which covers everything from the initial response in the event of a risk to measures to prevent a recurrence. We have also established an incident management process and commenced its operation.

Initiatives for the health of employees

Considering the health of employees as one of our most important considerations, we engage in various measures for allowing employees to work while maintaining their mental and physical health so that all employees can work vigorously.
We promote 100% participation in regular health checkups or stress checks and encourage employees aged 35 years or older to undergo comprehensive medical examinations and screenings for breast cancer, cervical cancer, prostate cancer, and brain health, with the goal of early detection and treatment of health risks. We also subsidize the cost of various medical examinations. In addition, as part of initiatives to promote mental and physical health and prevent illness, we adopted meetings and lectures with industrial physicians and industrial health nurses, and the “S.T. Health Hot Line,” a counseling service (staffed by outside professional counselors) accessible to all employees, as well as their spouses and dependents. In preparation for non-work-related illnesses and injuries, we have established a cumulative leave program to support employees in balancing work and leave.
As part of our initiatives for smoking cessation, we implemented a ban on smoking during working hours starting in 2018 and a complete ban on smoking inside buildings starting in 2022. In recognition of these initiatives, we have been certified by the Ministry of Economy, Trade and Industry as an “Outstanding Health and Productivity Management Organization” for four consecutive years, since 2022. Through health and productivity management, we aim to create an environment in which both employees and the company can grow, and all employees can play an active role.
