Initiatives in Health & Safety

Policy and Commitment

To prevent occupational accidents and health disorders at worksites and protect the environment, Shimizu works to strengthen occupational safety and health management and promote accident prevention activities, with the goal of zero fatal and serious accidents and zero public accidents.

Basic Health and Safety Policy

Basic Principles

Shimizu stands on the principle of respect for human life and human beings and places the highest priority on safeguarding the lives and health of our employees in all corporate activities. We have established a corporate culture that is grounded in safety and maintain a safe, comfortable work environment.

Measures for Achieving Our Goal

1. Shimizu operates a Construction Occupational Health and Safety Management System (COHSMS). We pursue enhancement of preventative safety measures through risk assessment and strive to reduce occupational accidents on a continual basis.
2. We recognize the importance of both safety and production in business activities, based on our policy of safety as a top priority. We ensure safe equipment by implementing redundant safety measures and other means and work to make construction procedures readily visible, from the construction planning stage onward.
3. We encourage suppliers and subcontractors to establish independent safety management^*, actively encourage disaster prevention conferences, and clarify the respective role and responsibilities of Shimizu and our subcontractors in promoting the prevention of accidents.
4. We recognize our responsibility as a business operator to further improve initial explanation of projects and training on job site rules to workers who are new to a job site. We work to ensure strict safety compliance among workers and eliminate accidents involving them.
5. We make sure that managers in charge of health and safety have the knowledge and dynamism to educate employees and develop them as promoters of compliance with laws and regulations (strict compliance with company rules for safety work) and accident prevention.
6. We have strengthened rules on working safely to eliminate exposure to dust, asbestos, and other materials that are harmful to health, and work to provide comprehensive education on preventing health hazards.

The policies above also apply to subcontractors to which construction work is outsourced.
Shimizu distributes the Supplier and Subcontractor Health & Safety Management Guidelines to subcontractors we outsource construction work to and facilitates independent and sustainable health and safety management by these companies.

Company-wide Health and Safety Plan for Fiscal 2025

"Raise Individual Safety Awareness—Achieve Zero Accidents through Teamwork"

Code of Conduct for Achieving Zero Accidents

All personnel involved at worksites must share a sense of ownership, and with a conviction to protect the lives and physical and mental well-being of oneself and colleagues, practice smooth communication and implement the PDCA cycle.
Departments, worksites, project leaders, and foremen are expected to help each worker strengthen their awareness of potential hazards and promote safety activities that encourage every team member to see safety as their own responsibility.

PDCA Cycle

P (Plan): Identify potential accidents and disasters based on risk assessment and proactively ensure safety by incorporating "double safety" measures into work plans and procedures.

D (Do): Share awareness of accident and disaster risks; employees, foremen, Safety and Health Supervisors, and work supervisors must fulfill their responsibilities and ensure safety through teamwork.

C (Check): Based on the new "Three Actuals" principle (Actual Site, Actual Thing and Actual Situation) with increased verification eyes, conduct site patrols and inspections to confirm safe conditions.

A (Act): If actual operations deviate from the plan, stop the work, reassess the risks, revise the plan, and communicate the changes to all stakeholders before resuming.

Key Measures

1. Eliminate fall and drop-related accidents (refer to fall protection equipment as safety belt)
2. Eliminate construction machinery and crane-related accidents
3. Eliminate collapse-related accidents
4. Eliminate public accidents, infrastructure damage, and fire incidents

System

Our health & Safety management structure (Executive Vice President and Representative Director) is headed by a safety & environmental officer, who is director and senior managing executive officer appointed by the president. The health & environmental officer is responsible for overseeing the company’s health and safety management. The head of the Safety Administration & Environment Division plans and implements specific activities and initiatives. At the branch level, each branch manager is responsible for planning and implementation in their own branch.
Twice a year, Shimizu holds meetings of the Safety & Environment Committee, where members, including the executive officer in charge of safety and environment, receive reports on health and safety activities and discuss and formulate matters related to the company-wide health and safety plan, along with measures and efforts to prevent the recurrence of serious accidents and incidents.
In addition, three times a year we convene the Company-wide Meeting of General Managers of Safety and Environment Departments to review health and safety activities at each branch, incorporate employee input into the company-wide health and safety plan, exchange views with branch offices to help streamline health and safety management operations and raise management standards, and share best practices and measures for preventing accidents and incidents.

Construction Occupational Health and Safety Management System

Our safety management method is to promote measures to prevent accidents by taking preventive safety measures that focus on universal potential hazardous factors.
At all work sites, applicable hazardous work is identified at the pre-construction review meeting before the start of construction. After the start of construction, we conduct risk assessments for each work procedure at individual pre-construction meetings and assign a person in charge to implement risk mitigation measures.
Since 2001, we have been operating an occupational health and safety management system based on Construction Occupational Health and Safety Management System (COHSMS) Guidelines to raise the level of our health and safety standards by effectively implementing the PDCA cycle.

Health & Safety Results

The LTI (lost time injury) Frequency Rate^* for FY2024 was 0.76, a 0.22 deteriorate from FY2023.

LTI (lost time injury) frequency rate: The number of deaths and injuries per million cumulative man-hours. Figures for all industries and for the construction industry represent accidents resulting in one or more lost work days, calculated on a calendar-year basis. Figures for Shimizu represent accidents resulting in four or more lost workdays, calculated on a fiscal-year basis.

Ratio of Offices Certified under OHSAS 18001

As of 2025, Shimizu has no offices certified under OHSAS 18001.

Response after an Accident

In the Event of a Fatal or Serious Accident

(Accident investigation)
If a fatal or serious accident occurs, the Division Safety Management Officer immediately goes to the site to take the necessary initial actions and conduct an accident investigation. The Director, Safety & Environment Division cooperates with the division’s investigation as necessary.

(Analysis of issues and review and establishment of countermeasures)

1. The Division Safety Management Officer directs the worksite in analyzing the issues related to the accident and reviewing countermeasures.
2. Based on investigation and analysis of the circumstances of the accident, the Division Safety Management Officer and Director of the Safety & Environment Division formulate and promote measures to prevent the occurrence of the same or similar accidents.

(Measures to prevent recurrence and similar accidents)

1. The Division Safety Management Officer confirms that measures to prevent recurrence and similar accidents are being implemented properly.
2. The Director, Safety & Environment Division issues directives and administrative notices to prevent the occurrence of the same or similar accidents.

In the Event of a Lost-time Accident

1. The Division Safety Management Officer reviews and confirms the accident report and the table of measures to prevent similar and repeat accidents prepared by the worksite and relevant department, and reports them to the Safety Department of the Safet and Environmental Division.
2. The Division Safety Management Officer and the Director, Safety & Environment Division issue administrative notices as necessary to prevent the occurrence of the same or similar accidents.

Initiatives

Efforts to Prevent Occupational Accidents

Accident Analysis

The following procedures are followed when responding to on-the-job accidents:

1. Provide information to the relevant people through the accident reporting system.
2. Perform an investigation of the accident and include safety staff in the investigation.
3. Formulate plans for and implement corrective measures to prevent recurrence of similar accidents based on the investigation and analysis.
4. Roll out measures internally, across the organization when necessary.
5. Accumulate accident data for use of risk assessments, etc. and prepare safety-related statistics.

By accident type, the most common was slip, followed by fall and drop.
There were 55 incidents in FY2024 that resulted in four or more days of absence from work, up by 10 from the previous year.
Falls remain one of the most frequent causes of accidents, often stemming from insufficient coordination between our company and subcontractors. To prevent such incidents, we identify fall-risk tasks each day, and our employees are required to visit the site before work begins to discuss potential hazards directly with those involved. These efforts are part of our ongoing commitment to ensuring safer on-site operations.
Based on analysis results and severity of accidents in FY2024, we will continue to prioritize eliminating fall and drop-related accidents in FY2025, while also focusing on the elimination of construction machinery and crane-related accidents, collapse-related accidents, and public accidents, infrastructure damage, and fire incidents, aiming for further reduction in accidents.
Ensuring safety is fundamental to construction and manufacturing, and it forms the basis of client and public trust. By working together—our company, subcontractors, foremen, and workers—we aim to fulfill our roles and responsibilities and achieve zero fatal, severe, and public accidents.

Internal reporting system

Sharing Information and Activities to Prevent Recurrence

At the job site, we and our suppliers and subcontractors work together on a regular basis to perform basic and routine safety management tasks as part of a safe construction cycle. We implement a safe construction cycle to facilitate information sharing such as coordination between work areas and prevent accidents from occurring.

Safety Patrols by President

Every year during National Safety Week and National Industrial Health Week, Shimizu carries out worksite safety patrols led by the President and members of the Company-wide Safety Committee to review construction progress and on-site safety measures. These patrols call for compliance with work procedures and basic rules, while also emphasizing thorough measures to prevent heat illness. In FY2025, the patrols covered building construction and civil engineering sites in Tokyo under the jurisdiction of the Tokyo Branch.

Supporting Health and Safety Education for Partner Companies

With regards to the health and safety trainings listed below, Shimizu provides support and guidance to its business partners such as by supplying training material, lending venues, and dispatching instructors.

1. Safety training for workers upon initial employment, upon initial dispatch to a job site, and upon changes made to their assigned work
2. Special training for workers assigned to work legally designated as dangerous or hazardous
3. Training for foremen and safety and health officers
4. Training for workers assigned to dangerous and hazardous work and capacity building training for workers assigned to health and safety operations
