Workers Protected Under IHI’s Occupational Health and Safety Management System

The IHI Group has established standards laid out in both the occupational health and safety management system at works and research facilities and the occupational health and safety management system at construction sites.
These standards apply to all Group works, research facilities, and construction sites, and extend to all workers at these sites, including Group employees and partner company employees.

Education/Awareness Building

Employee Training and Education

The IHI Group provides education on health and safety specific to each position to everyone from new employees to management.
Works division employees undergo Supervisor Safety Training (SST) to learn about health and safety when promoted to assistant foreman or foreman.
Design and development employees on construction sites undergo Construction Safety Standard Training (CSST) to learn the ins and outs of construction health and safety as new and senior employees or group leaders and management.
Employees who are candidates for construction site director or supervisor undergo Site Manager Safety Training (SMST) to learn about on-site health and safety. We also provide follow-up training thereafter to expand knowledge about health and safety.
The IHI Group also cultivates trainers for the SST, CSST, and SMST programs as a Group.
In addition, the Health and Safety Committee constantly reflects feedback from employees based on standards laid out in the occupational health and safety management system at works and research facilities.

Health and Safety Management

The IHI Group is committed to eradicating occupational accidents through Five Safety Principles that act as a Group-wide code of conduct.
We assess risk at our works and construction sites to identify and mitigate potential hazards through strict verifiable countermeasures. We conduct regular health and safety training for all of our employees to eradicate occupational accidents. In addition, we give support to business partners at works and construction sites to improve health and safety management in a cooperative effort to ensure safe working environments.
We carry out these health and safety initiatives as part of the occupational health and safety management system.

Activities to Reduce the Risk of Occupational Accidents

The IHI Group promotes health and safety activities upon defining occupational health and safety policies, targets, and plans according to the standards set as part of our occupational health and safety management system. Our annual occupational health and safety management evaluations also drive improvements to eradicate occupational accidents.
We define items requiring our attention as well by identifying dangers and hazards related to machinery, facility, chemicals, and other such factors in order to reduce and eliminate them.
We rolled out the IHI Group Basic Safety Principles for the six most common types of occupational accident in fiscal 2020 and are focusing on eradicating these occupational accidents throughout the entire IHI Group.

FY2023 IHI Group Health & Safety Management Priority Policy

Due Diligence to Occupational Health and Safety during Projects

Concerning project execution, the IHI Group strives to identify and evaluate occupational health and safety risks in advance and take any necessary steps to reduce them. Moreover we carry out safety measures, which include IHI Group Basic Safety Principles, with our business partners.

Investigation Procedures and Observations in the Event of an Occupational Accident

The IHI Group assesses and analyzes factors of any occupational accidents through Group-wide disaster investigation procedures. The use of standardized accident report formats allows for swift sharing of information about an accident in the Group.
An analysis and evaluation of the accident information collected helps put in place measures to prevent any recurrence of the same or similar accidents throughout the Group.

Health Management

The IHI Group believes greater employee well-being* helps improve individual productivity and invigorate their workplaces. That is why we strive for both physical and mental health management.
Our mental health education takes both reactive approaches, such as detailed follow-up with individuals suffering from mental illness, programs to help employees return to work, and reintegration programs, as well as active approaches, such as education to teach mental toughness to improve motivation and performance. These educational programs aim to build an enthusiastic workplace for everyone, from new employees to senior management.
We also provide additional health measures to improve lifestyle habits and prevent metabolic syndrome, smoking, and other such lifestyle illnesses and issues in addition to the spread of COVID-19.

Well-being: condition where body and mind are healthy, a person is able to work in a lively manner, and both employees and organization are full of vitality

FY2023 IHI Group Health Care Priority Policy

Carry out both offensive and defensive measures to improve each individual’s energy and create a workplace where everyone can feel the joy of working from the perspective of physical and mental well-being, which is the foundation for everything.

  1. Offense measures: Improve the energy of individuals and the organization
    • Hold workshops and events for health, which forms the basis for participation and activity. Theme: The effect that sleep, nutrition, exercise, etc., have on energy
    • Well-being activities held at each workplace (creating a workplace utilizing health surveys, etc.)
    • Hold programs that increase the engagement of management
  2. Defense measures: Establish a system that can promptly address physical and mental illness stemming from a change of environment
    • Expand a revised program that further increases coverage inside the Group and supports early response, early recovery, and second chances.

Activities to Promote Health Management

The IHI Group is working on activities that improve the well-being of our Group employees and the organization in order for outlined in Project Change toward overcoming operating environment changes to drive value creation.
In fiscal 2022, we selected workplaces for well-being improvement and promoting activities to improve the workplace with a focus on management and communication.

Topics Covered Under the Main Dialogue Between Employee Representatives and Management on Health and Safety

The IHI Group convenes the Central Health and Safety Committee every year to engage in a labor-management dialogue about employee health and safety.

Health Management of Employees Involved in the Nuclear Power Business

The IHI Group has an established set of Radiation Control Standards for preventing radiation hazard to our employees. Based on these standards, we regulate the exposure of all IHI Group employees and partner company employees engaged in radiation work at nuclear power sites to evaluate radiation damage caused by exposure (exposure dose control).
These standards are stricter than the radiation protection regulations and guidelines issued by the Japan Ministry of Health, Labour and Welfare, which we use to manage exposure doses in order to promote good mental and physical health. Furthermore, IHI’s industrial physicians provide health checkups along with health advice.

Management Resilience Program

The IHI Group started a Resilience Program for its management beginning in fiscal 2021. Our industrial physicians give lectures throughout the year covering four topics where workers learn about the body (sleep, exercise, and nutrition), emotion, consideration, and spirituality and put them into practice.
The purpose of this program is not only to maintain and improve physical strength, but through these initiatives, to further build an individual and organizational vitality and strengthen cooperation among Officers. By making changes within the management class that leads our organization, we will continue making efforts to improve the health of the organization as a whole by striving for the happiness of our employees and improving the organization’s corporate value.
