Respect for Employees：Health and Safety Initiatives
Toyo Seikan Group is proactively engaged in health and safety activities to ensure that all parties involved work in a safe and healthy environment, including not only employees but also external stakeholders, partner companies, and contractors.
Our safety activities are carried out mainly through committees organized by each company. These include workplace safety patrols, preventing the recurrence of similar accidents, and risk prediction activities, all of which are carried out continuously based on an activity plan.
In our health activities, we focus on preventing lifestyle-related and occupational diseases, promoting mental health measures, and other areas in accordance with our annual activity plan.
Furthermore, together with our partner companies and contractors, we carry out safety activities and disaster prevention events at our workplaces. Through these efforts, we aim to create a working environment where everyone can work with peace of mind.
Occupational Safety and Health Policy
Toyo Seikan Group clearly defines its "comfortable working environment" in the "Toyo Seikan Group Code of Conduct," and is working to create a workplace where all people can work with peace of mind.
Each operating company strives to ensure and improve the health and safety of employees and takes the necessary measures to create a safe and comfortable workplace based on labor agreements concluded with labor unions and work regulations.
Occupational safety and Health Systems of Each Group Company
At each domestic operating company of Toyo Seikan Group, the Central General Safety and Health Officer (a director or executive officer) appointed by the president appoints a general safety and health manager at each site. The general safety and health manager at each site establishes a safety and health committee and builds a safety and health management system at the site.
The Health and Safety Committee at each site is an organization that promotes safety and health management, and holds a joint health and safety committee meeting once a month with labor and management.
In accordance with the law, the committee is composed of the general safety and health manager, safety managers, health managers, industrial physicians, and members from both the company and the labor union. Half of the members are appointed based on recommendations from the labor union. If any major safety and health issues or concerns are discovered, they are promptly reported to the general safety and health manager, who issues instructions for corrections and countermeasures to the Safety and Health Committee Secretariat, which works with the relevant departments to make improvements, and the details of these improvements are then rolled out to other bases.
Toward the Prevention of Occupational Accidents
To prevent workplace accidents, the central health and safety manager at each company formulates an annual activity plan for each company and carries out the following activities.
As part of our safety activities, we hold a "Safety and Health Committee" every month at each site, and strive to reduce risks by continuously and proactively carrying out activities such as formulating policies suited to the characteristics of the business site, conducting workplace safety patrols, taking measures to prevent the recurrence of similar accidents, and engaging in KY (hazard prediction) activities.We also share safety information with our partner companies, such as examples of industrial accidents and countermeasures, and work together to promote safety activities.As for health activities, we are working to prevent lifestyle-related diseases and occupational diseases, and to promote mental health measures.
We also operate a system for collecting information on near misses, defects, and improvement suggestions from employees.
