Occupational Health and Safety

Basic Stance to Ensure Health and Safety

We strive to engage in construction activities while giving full consideration to health/safety issues, quality control and environmental preservation. We strictly comply with all relevant laws, regulations, and other requirements. We will accelerate Work Style Reform and productivity improvement by implementing digitalization, and further promote carbon neutrality through decarbonization and use of green electric power, aiming to reduce CO2 emissions generated from our business activities. Through these efforts, we strive to achieve sustainable development and gain trust from all stakeholders.
Under our ESG-oriented management philosophy and out of respect for humanity, we will place the highest priority on construction safety, and entirely commit ourselves to preventing occupational accidents. Furthermore, we will strive to ensure customer satisfaction by delivering high-quality construction products and providing related services, and to establish social credibility through environmentally friendly manufacturing. We will promote efficient and effective operations by continuously improving our systems to ensure occupational health and safety, product quality and environmental protection with the participation of each and every employee.

Occupational Health and Safety Guidelines

  1. Committing ourselves to prevent occupational accidents and all other types of accidents, including public accidents
  2. Preventing the spread of occupational diseases and COVID-19, promoting mental and physical health, and creating a comfortable work environment
  3. Establishing an open workplace culture and implementing safety and health activities in cooperation with employees and subcontractors, aiming to improve the level of safety and health

Implementation of PENTA-COHSMS

Our commitment to construction safety stems from basic respect for humanity. We have established an occupational health and safety management system to 1. eliminate/reduce potential risk of occupational accidents, 2. promote workers' health and create comfortable workplaces and 3. improve corporate standard for health and safety.
We are one of the first companies in the construction industry to receive the "COHSMS Certification" from the Japan Construction Occupational Safety and Health Association in 2008, and have been renewing the certification by undergoing an audit every three years. We have named said certified system "PENTA-COHSMS" and are conducting continuous health and safety management in compliance with the system.
Following the revision of the COHSMS Guidelines to "NEW COHSMS" by the Japan Construction Occupational Safety and Health Association in April 2018, we revised at our end our proprietary "PENTA-COHSMS" by including the addition of mental health initiatives.
While adhering to the standards in the above certification, we will aim at further enhancement of the system and co-work with our subcontractors to ensure its implementation and operation. By improving the level of safety and health management, we will strive to take preventive measures to avoid occupational accidents.
Several of our overseas offices have acquired the international standard for occupational health and safety management systems (ISO 45001), and we are working to continuously improve our occupational health and safety performance through the operation of the system.

Implementation of POC Standard at Home and Abroad

We have been implementing an occupational accident prevention and quality management measures that prioritize safety and quality in Japan and overseas, and named it the Penta-Ocean Construction Standards. We spread these standards in Japan and overseas and carry out occupational accident prevention activities in collaboration with subcontracting companies.

<Specific efforts>
·Special Safety Day (March 30), Safety Contest (1st day of every month), Safety Week (preparation period: June 1-30, the actual safety week: July 1-7) in overseas
·Implementation of Penta-Ocean Construction self-regulation and accident prevention activities (Exercise 333, etc.) in overseas

Environment, Health and Safety Committee

Under the CSR Committee chaired by the President and Representative Director, we have established the Central Safety and Health Environment Committee as a central organization for safety and health environment conservation activities. This Committee deliberates and decides on basic policies and measures to effectively promote health and safety environment activities.
Additionally, based on an annual plan, we regularly carry out the Central Safety and Health Environment Committee Patrols in all branches.

Risk Assessment

Our risk assessment model refers to the database containing some 1,000 risk factors derived from 5,000+ past disaster cases. In construction offices, we use this database to identify risk factors, which are then shared with subcontracting companies, in each phase of work and during the project planning. The risk factors identified through above risk assessment are linked to disaster information, and situational photos and maps from actual disaster records are used to determine risk reduction measures. Thus, we are working together with our partner companies on disaster prevention measures to avoid the same disaster scenarios.
We also work on implementing AI-based risk assessment protocols.

Our Construction Safety Track Record

  • *All numbers are unconsolidated figures (POC only)
  • *Frequency rate indicates the frequency of accidents. Number of fatal causalities due to occupational accidents/total number of actual working hours x 1,000,000
  • *Severity rate indicates the severity degree of an accident. Total number of lost working days/ total number of actual working hours x1,000
  • *Accidents causing 4 or more days lost

Initiatives to Enhance On-site Communication

Since 1998, we have been promoting a Compassionate and Friendly Greeting Campaign that aims to achieve no accidents and no illnesses, and creating a safe, healthy, and lively workplace culture based on the stronger harmony among people. In particular, we make every construction staff to call each other by name for deepening the sense of fellowship.

Initiatives to Prevent "Specific hazards"

We have designated crash accidents, fall accidents and heavy machinery (crane) accidents as "Specific Accidents" and focus our efforts for preventing these accidents amongst all other accidents. Regarding the prevention of crash and fall accidents, we introduced a "Immediate 'Red Card' System for Workers Who Do Not Use Safety Belt*", which suspends a worker from the construction site when he/she is found not using a fall prevention equipment (commonly, a safety belt) in a place where a safety belt is mandatory. As for the prevention of heavy machinery and crane accidents, we enforced the "Zero Heavy Machinery Accident Declaration" to reconfirm prohibition of entering a working radius of the equipment, and to assign guards to prevent any entry. Also, we enforced the "Zero Crane Accident Declaration", "Exercise 333*.

  • *Workers who were suspended will return to the site after recieving the safety training again.
  • *Exercise 333: (1) 3 m away from the suspended load when slinging. (2) Stop hoisting the lifted load at 30 cm. (3) Roll up after counting 3 seconds when hoisting the lifted load.

Initiatives to Ensure Thorough Communication between Work Shifts

We are making efforts to stop unscheduled work by ensuring communication among staffs when changing the work schedule. When it is unavoidable, we request to prepare a "Record of Meeting for Unscheduled Work" and notify the staff and subcontracting companies.

Special Safety Day

Special safety day (March 30th)
On March 30, 2014, a major accident occurred in the Okinotorishima port construction site, where seven precious lives have perished. Every year on March 30, we hold a memorial service with the bereaved families and the client's attendance. We designated the March 30 as a Special Safety Day, where we conduct simultaneous onsite inspections to reaffirm safety.

Fire prevention day (April 20th)
On April 20, 1998, a major fire occurred at our construction site, with one deceased, 16 people mildly/seriously injured, and the building completely burned down. Taking this accident as a lesson, we designated April 20 as Fire Prevention Day to reconfirm fire prevention measures.

Safety as a Top Priority

 Cooperative health and safety initiativesDetails(Japanese only)

We are engaged in various health and safety promotion activities to eliminate occupational accidents.

Cooperative Health and Safety Initiatives with Subcontracting Companies

Occupational Health and Safety Council

To ensure quality and safety together with subcontracting companies, we have established the "Penta-Ocean Construction Labor Safety Council Association" and "Labor Safety Councils" at all branch offices, and 1,084 subcontracting companies have joined. The Labor Safety Councils are engaged in various activities to improve knowledge and skills related to labor safety, to prevent accidents, and to build a smooth cooperation between POC and the subcontracting companies.

<Examples of Penta-Ocean Construction Labor Safety Council's Activity>
(1)Safety and health patrols
Based on an annual plan, the headquarters, branches, and subcontracting companies perform patrols on a regular basis, in addition to the President's patrols twice a year.
(2)Safety and Health Environment Promotion Contest
The headquarters, branch offices, and the Labor Safety Councils co-host a "Safety and Health Environment Promotion Contest" in June, which is the preparation period for National Safety Week held in July every year.
The President/Representative Directors join several Safety and Health Environment Promotion Contests nationwide every year to strengthen efforts for safety and health activities.
(3)Implementation of various educational seminars and trainings
Various education and training programs (4)Other educational seminars/trainings
Seminars for association senior members, business owner education, risk sensitivity education, etc.

Excellent Foreman Award System

Since FY 3/14, we have an Excellent Foreman Certification System to further secure and train future leaders and improve the treatment of construction engineers. In FY 3/23, 431 foremen were certified, and we provided an additional 2,000 yen benefit per day for certified foremen, 1,000 yen benefit per day for foremen who worked more than 100 days a year, and social insurance premiums for the allowance borne by the business owner are paid separately.

The Foreman Committee

We organize foreman's associations (organizations consisting of foremen and safety and health managers of multiple subcontracting companies) at each site to raise awareness of safety and health among all workers.

Work Style Reform Promotion of Subcontracting Companies

Partnership Building Declaration

POC practices ESG-oriented CSR management, believing that the greatest contribution to society is the construction of high-quality infrastructure. Through sincere corporate activities, we aim to be an attractive company in the eye of all stakeholders, including clients, society and partner companies. In order to support our partner companies with their Work Style Reform and secure future workers, we promote initiatives such as implementing the Declaration of Adherence to Price Quotations, paying 100% of construction costs in cash, providing incentives for achieving two days off per week and applying for the Construction Career Development System on behalf of our partner companies.

Labor Cost Correction in Shift-type Holiday Acquisition of Skilled Workers

For the skilled workers whose salaries may fluctuate depending on the number of working days, we implemented an initiative to stabilize their income and raise their awareness, as well as for subcontracting companies. Starting with new orders received by POC from July 2019, we provide a premium compensation for labor costs of skilled workers who take more days off than the site-closure targets set at each site.
We also revised the correction factors used for calculation for projects newly received in July 2020 onwards. The improved system is easier to use and covers a wider range of contents.

Cash Only Payment to Subcontracting Companies

In order to strengthen the management base of subcontracting companies, promote social insurance coverage, and encourage Work Style Reforms at sites, we make all payments to subcontracting companies in cash. Starting with new contracts from July 2017, payments to subcontracting companies (including for construction materials) were changed from bill payments (including electronically recorded credit payments and due date payments) to cash only payments. The transition to cash payments was completed in FY 3/19.

Aiming at 100% Enrollment in Social Insurance Policy

In 2015, we created an "Internal Guideline for the Promotion of Social Insurance Subscription by Subcontracting Companies" and are making company-wide efforts to ensure that all subcontracting companies are covered by social insurance. Regardless of project criteria (public or private), we require primary subcontracting companies to submit quotations that clearly indicate the breakdown of benefit and welfare expenses designated by law, to ensure workers' 100% social insurance coverage. By rule, we do not contract with companies that do not subscribe to social insurance unless there are special circumstances.
As of FY 3/23, the social insurance coverage rate for primary subcontracting companies is 100%, and the social insurance coverage rate for workers of primary subcontractors is over 99%.

Promotion of Construction Career-Up System (CCUS) Registration

The Construction Career Upgrade System (CCUS) is an important tool for improving compensation structure of skilled workers. In order to promote its implementation, we made it mandatory for workers to register for CCUS onsite and installed card readers for construction projects worth 100 million JPY or more. Our CCUS operation is linked to the Green Site, which significantly reduces the registration task for POC and for the subcontracting companies. In order to promote CCUS registration of primary and secondary subcontractors. We extended the free-of-charge registration service for unregistered companies until March 2024, and conduct the service throughout the year. In addition, in 2020, we established an "Inquiry Support Team" at the headquarter office and for subcontracting companies to provide support by responding to questions and consultations by phone and email, and by providing guidance on registration.
