Environmental and Safety Management System

Mitsui Kinzoku Group has established the Supreme Safety & Environmental Meeting as a place to deliberate and determine the most important matters related to safety and the environment. Guidelines and action plans determined at the Meeting are spread to each site by the Environmental and Safety Supervisory Manager (General manager of the Environmental and Safety Dept.) under the direction of the Chief Environmental and Safety Officer. Each site has a chief person responsible for managing environmental safety, who makes sure that the required actions are being reliably executed.

Reporting to the Board of Directors

Progress of safety plans, occupational accidents and implementation of measures to prevent recurrence are reported once a month at the Executive Council, which the President attends. The President (Representative Director) or the Chief Environmental and Safety Officer (Director) reports important matters to the Board of Directors for monitoring and supervision.

Meeting of General Managers in Charge of Safety and Environment

The Environment and Safety Department holds a meeting of general managers in charge of safety and environment once a month. The Chief Environmental and Health Officer (Director) and the general managers in charge of safety and environment at each business unit participate in the meeting, with a corporate auditor and labor union representatives attending as observers. In addition to confirming the progress of safety plans and reviewing safety performance, the meeting analyzes the causes of each accident that has occurred at each site in Japan and overseas and discusses how to prevent recurrence. Furthermore, the meeting regularly confirms the implementation of measures to prevent recurrence and the deployment of these measures at each site, identifies areas for improvement, and takes thorough measures to prevent accidents. The agenda details of the meeting are reported to the members of the Board of Directors.

Health and Safety Management System

In FY2020, all major sites of Mitsui Kinzoku Group completed the transition to the occupational health and safety management system, ISO 45001. For small-sized sites, we developed an internal certification system. At each site we work to realize an upward spiral motion by going through the PDCA cycle in accordance with the management system. Improvements to the issues identified by the review are incorporated into measures such as risk assessments as well as health and safety training.
We conduct safety risk assessments following the management system when planning new projects and when building or remodeling facilities, to prevent accidents and mitigate risks. Existing facilities are periodically checked for safety to incorporate the latest technology and to assess the effects of long-term operation.

Labor-management activities

Each site holds a Health and Safety Committee meeting where labor union representatives and site managers attend to deliberate on measures in order to prevent occupational accidents and health problems.
Meetings of the Central Health Act are also held once a year in order to share company policies and information on occupational health and safety at each site. The attendees of the committee meetings are as follows; the Chief Environmental and Safety Officer, the Chief Environmental and Safety Administrators of each site, and the officer in charge of safety at labor unions under the Mitsui Mining & Smelting Workers Union.
We have concluded an agreement on health and safety with the Mitsui Mining & Smelting Workers Union and implement measures for occupational health and safety based on the agreement.

Internal Safety Audits

Teams made up of safety officers from each business division and the Environment & Safety Department conduct safety audits of each site.
They check aspects such as action taken to address issues identified in the previous audit, execution of the safety and health management program, enhancement of the intrinsic safety of equipment, chemical substance risk assessments and the status of safety training. They then conduct a field audit of each site. The audit results are immediately shared with the management of each site.

Health and Safety Training

Each production site improves the safety awareness of their employees by conducting KY (“Kiken Yochi ” meaning “hazard prediction”) activities before starting operations, and giving experiential risk training by experienced employees.
Furthermore, at each workplace the workers and supervisors talk about safety issues, implementing training to ensure the safety and working on safety compliance activities thoroughly.
Information on work-related accidents within the Group and training materials are available on the intranet so that employees can review and refer to them at any time.

Accident Prevention Efforts

We are working to prevent recurring accidents and eliminate major accidents.

 1.Investigation of accident causes and prevention of recurrence
  After an accident occurs, we simulate the scene of the accident, investigate the cause, discuss measures
  to prevent recurrence, and disseminate the information to each site. We also review our safety standards
  and incorporate the accident into the Group's training programs as a case study as needed.

2.Formulation of the President’s Policy on Important Health and
  Safety Issues 

  We analyze every year’s safety performance results and the status of accident occurrences, deciding on
  the President’s Policy on Important Health and Safety Issues as a next measure that should be promptly
  and intensively implemented.

 3.Study of accidents at other companies
  We analyze the causes of accidents that have occurred at other companies by using accident case
  studies provided by the Japan Mining Industry Association, the Japan Federation of Basic Industry
  Workers' Unions, and other organizations. We make explanations and case studies of those examples
  that will be helpful for our group in training and training programs within the Group.

  Introduction and deployment of a Lockout System
  The Lockout System is a system that shuts off and locks the power source of machinery and
  equipment to prevent occupational accidents caused by mishandling and to protect the safety
  of workers. Implementation of the lockout system, along with training on its introduction, began
  at each site in FY 2019. Currently, we are regularly reviewing and improving the proper operation
  of the system.

 4.Elimination of major accidents
  Intrinsic Safety of Equipment and Preventive Management
  In order to ensure preventive management, we are improving equipment and work processes to
  remove or minimize sources of hazard identified in our risk assessments.


  Enhancement of Hazard Simulation Training
  In addition to hazard simulation training at work sites and on actual items, we have introduced VR
  (Virtual Reality) hazard simulation equipment at our manufacturing sites to simulate serious accidents.
  Trainees are receiving this training only at their sites due to movement restrictions caused by the
  pandemic of Covid-19. After the lifting of movement restrictions, we plan to further utilize the VR
  hazard simulation training by providing exchanges between sites.


President’s policy on important health and safety issues for 2024(*)

  1. [Preventive management]
    Promote understanding of equipment structure and work standards. Review the implementation status and effectiveness of accident-prevention measures at our
    company and other group companies by utilizing the Health and Safety Committee. Practicing intensive warm-up stretching prior to operation with the aim to prevent
    tripping, back pain, and aging.
  2. [Improving the intrinsic safety of equipment and reviewing work content]
    - Ensure the intrinsic safety of our facilities and equipment according to actual conditions in the workplace. Especially taking necessary measures to protect
    personnel through safety equipment, fences, etc.
    - Review the work content of older workers to take into account characteristics such as reduced physical strength.
  3. [Safety compliance activities]
    Eliminate accidents caused by rule infringements by continuing the thorough implementation of safety compliance activities: "Teach the rules, obey the rules, caution others."
  4. [Risk sensitivity]
    Improve risk sensitivity by promoting "hiyari-hatto" (close call incidents) activities and risk assessment, as well as ensuring hazard prediction before non-routine
    In addition, conduct hands-on education (including external or VR training) in a planned way.

(*)The policies are based on the analysis of the accidents occurring between January and September 2023, and enacted in October.

Health Management

Our Approach

Mitsui Kinzoku Group aims to continue to contribute to society with valuable products. In order to achieve this goal, it is necessary to create a work environment where all employees can maintain both physical and mental health in order to exercise their individualities and ability. We become even more vibrant company through keeping our employees health.

Promotion System

Mitsui Kinzoku Group promotes initiatives to maintain or improve the employee’s health, establishing cooperative relationships with general affairs department of headquarters and general affairs/human resources department at each site so that the initiatives are well performed at the whole company.

Our Initiatives

At each site, we strive to unitarily manage each employee’s personal data on health and standardize how to handle the information. In addition, we implement stratified education program and provide information on health through the corporate magazine, the intranet and lectures by occupational health physicians in order for each employee to improve health literacy. Various kinds of exercise events are also held for the employees to make their life-style better.

Regarding employees’ mental health, the stress check has been conducted in accordance with the Industrial Safety and Health Act. The stress check in FY2021 shows that 15.6% of the subjects of the test have high levels of stress, which is an increase of 2.3% from the previous fiscal year.

Also, we use the results of the stress check for employees’ self-care and for understanding the strength and weakness of each department based on the results of organizational analyses, working to improve the workplace environment.
