Basic Approach

As a corporate group responsible for the stable supply of energy and materials, the ENEOS Group believes that ensuring safe operations is the basis of our business survival and social credibility, as well as the source of our competitive edge.
Based on this understanding, safety has been prioritized in the ENEOS Group Philosophy, and our basic policy on safety and security has been stipulated in the ENEOS Group Code of Conduct.
Based on the above, each Group company has established its own safety policy in accordance with its business characteristics and assesses risks pertaining to occupational safety, thereby ensuring multiple layers of effective safety activities. Specifically, we aim to enhance our safety activities and safety training programs, in which the employees of our contractor companies also participate, and we have established preventive and emergency measures to cope with all manner of accidents, problems and natural disasters.
We check with our labor unions to make sure efforts are being made to maintain the facilities needed to ensure the health and safety of labor union members (Article 90 of the Ancillary Agreement to the Labor Agreement).

ENEOS Group Safety Policies

Each ENEOS Group company has established a policy on occupational health and safety which states its commitment to prioritizing and fully ensuring the safety of its workers.

    We aim to ensure that nobody gets hurt and to eliminate accidents.
  • JX Nippon Oil & Gas Exploration
    Ensuring that Health, Safety and Environment (HSE) considerations are given prevailing status over our other business considerations.
  • JX Metals
    We place the highest priority on ensuring the health and safety of people working in all areas of business operations.

See the following for further details on the safety policies of the Group’s principal operating companies.


For information about our structure, see ESG Management Structure.
We have established the ENEOS Group Safety, Health & Environment Council, chaired by the officer responsible for the Safety, Health & Environment Department at ENEOS Holdings. The council meets, in principle, twice annually, to share information on the status of occupational injuries and the implementation of safety activities at ENEOS Holdings and its principal operating companies, as well as to discuss and develop measures to prevent occupational injuries.

Operation of Safety Management System and Status of Certification

Each Group company has built safety management systems tailored to its respective business characteristics. Our companies are continuously making efforts to raise safety awareness and prevent occupational injuries through means such as implementing regular safety education and training, conducting investigations into the causes of incidents and formulating and implementing measures to prevent recurrence.
ENEOS has established and implemented its own safe operations management system (SOMS), which conforms to ISO standards, at all of its refineries and plants.
JX Nippon Oil & Gas Exploration has adopted its own HSE1 management system (HSEMS), which conforms to ISO standards. Through HSEMS system management, the company has established an integrated safe operations framework that includes overseas business sites.
JX Metals is moving ahead with the acquisition of ISO 450012 and JIS Q 451003 certification, and by March 2023, 13 domestic business sites had obtained certification. The remaining business sites, including those that have newly joined the JX Metals Group, plan to acquire certification in fiscal 2023 and beyond.

Results of Major Initiatives for Ensuring Safety

The ENEOS Group prioritizes and is fully committed to the safety of its workers. We have set material targets for zero serious occupational injuries (occupational fatalities) and a total recordable incident rate (TRIR)* of 1.0 or less, and we implement comprehensive safety activities and safety training for employees, including those of contractor companies.
In fiscal 2022, we had zero serious occupational injuries (occupational fatalities) and TRIR of 1.0, thus achieving our material targets. We believe that the achievement of these targets attests to the effectiveness of our safety activities.
A total of 29 workers sustained lost-work-time occupational injuries in fiscal 2022. While this was a decline from 43 workers in the previous fiscal year, improvement is still needed. As many of these incidents have occurred in the course of work activities, we will enhance our ongoing safety activities to continue reducing lost work time. We have also found that a certain number of accidents occur outside of work, such as when moving from one place to another. As a preventive measure for accidents that occur outside of work, we seek to raise safety awareness by sharing situation analysis and cause investigation results for individual incidents.
As a company group that provides work environments for a large number of employees, including those of contractor companies, we will continue to implement effective safety activities in accordance with the characteristics of our businesses as part of our efforts to eliminate occupational accidents.

  • *Total recordable incident rate (TRIR) is the number of occupational injuries per million working hours (non-lost-time occupational injuries + lost-time occupational injuries and fatalities)

Major Initiatives

Increased Scope of Data for TRIR and LTIR

As part of the management of safety-related targets, the three principal operating companies use TRIR and LTIR as indicators. In fiscal 2022, we decided to expand the scope of data for TRIR and LTIR.
In addition to the original scope of data, which includes company employees and employees of contractor companies at business sites under the direct control of the three principal operating companies, the expanded scope of data will also cover the group companies of each of the three principal operating companies. We plan to make preparations for dissemination to and training for these companies in fiscal 2023, and start collecting data in fiscal 2024.

Safety Activities

Group companies are working to raise safety awareness and enhance safety management. Risks at production and manufacturing sites are managed using a PDCA cycle to identify hazards, assess risks and take necessary risk mitigation measures and assess their effectiveness.
Every year in July, ENEOS releases a video message on safety by its president to all employees, demonstrating the company’s top-down commitment to safety. At its refineries and plants, the company has implemented a behavior-based safety (BBS) system that is used to facilitate safe operations by focusing on individual behavior.
JX Nippon Oil & Gas Exploration has implemented various safety activities at its business sites both overseas and in Japan (Vietnam, Malaysia, and Nakajo). For example, workers have stop work authority (SWA) so that anyone can halt work in the event of unsafe behavior. Furthermore, we encourage the active participation of frontline workers in safety to help raise the safety awareness of the entire workforce, through activities such as Unsafe Condition Unsafe Act (UCUX), where workers can point out or propose improvements at any time to resolve unsafe conditions or behaviors.
JX Metals is working continuously to improve safety awareness and sensitivity to risks through means such as enhancing hazard simulation training at its business sites and developing and implementing safety training materials based on past accidents (videos re-enacting occupational accidents, e-learning, etc.).

Group-wide Safety Action Items

In order to prevent serious occupational injuries, we designated preventing falls, separating people from heavy machinery, and preventing heatstroke as the three safety action items for the three principal operating companies. We established these action items in the ENEOS Group guidelines in February 2020.
Since fiscal 2021, we have reflected the three safety action items, positioned as common issues for the three principal operating companies, into the safety activities of each company. The principal operating companies are also sharing safety initiatives with their own group companies as part of their efforts to eliminate occupational injuries.

Group-wide Safety Action Items
  • Preventing falls
  • Separating people from heavy machinery
  • Preventing heatstroke

Hazard Simulation Training Using Virtual Reality

Virtual-reality training equipment

The ENEOS Group launched the ENEOS Group Safety Education Center in Hitachi City, Ibaraki Prefecture in 2013 to enable workers to learn about the hazards inherent in day-to-day operations through simulated experiences. Since fiscal 2017, the center has implemented a training program unique to the Group using virtual reality (VR) technology.
The program enables workers to feel what it is like to be involved in an accident and think about victims’ psychological state, as well as accident causes and preventive measures.
Using VR technology, trainees can experience simulated accidents that cannot be safely replicated in the real world, such as steam explosions, being struck by heavy machinery, getting caught in rotating equipment, and falling from heights. These experiences improve their ability to detect workplace hazards to avoid or deal with when they occur. Since the launch of the program, VR experiences with scattering of chemicals, getting fingers caught in slings, grinder recoil, falling down stairs, electric shock, and fire caused by static electricity have been added to the program, further enhancing the content of the training.
In fiscal 2022, 1,013 persons participated in training at the facility, bringing the total number since the establishment of the center to 13,353.
We have also installed hazard simulation equipment at each of our production sites (ENEOS: 11 sites, JX Metals: 7 sites). Workers at these sites, including those from contractor companies, are required to undergo training using this hazard simulation equipment before engaging in onsite work. With these and other efforts, we are working to ensure safety across the entire Group.

Using AI to Ensure Safety While Walking

In fiscal 2022, ENEOS introduced an AI-driven program for analyzing walking motion as a way to improve movement safety. The program uses a special device to measure a person’s walking speed, stride length, center of gravity, and other elements to determine the level of safety in the walking motion. The program then uses the results to provide suggestions for exercises or other ways to improve safety while walking.

Improving Human Skills

As human factors are a major cause of occupational accidents and injuries, we have focused for many years on training to arm employees with the knowledge and technical skills needed to implement procedures and rules without fail. In recent years, however, there is growing awareness in the manufacturing industry, referencing leading initiatives in the healthcare and airline industries, about the importance of stepping up initiatives to improve non-technical skills, including status confirmation of work environments and communication among workers, in addition to compliance with procedures and rules. Accordingly, we are incorporating knowledge and activities for the improvement of these non-technical skills.

Foundation for Safe and Stable Operations

In the ENEOS manufacturing division, we refer to these non-technical skills as human skills, which we have stipulated in the activity guidelines for improving human skills in the manufacturing division. In accordance with these guidelines, at all of our plants and refineries, top management shares the importance of human skills, and systems have been put into place for the implementation of various forms of education and training and the integration of the resulting skills into existing daily safety activities in the workplace. In this manner, we are working to improve the human skills of all employees in the manufacturing division to prevent human-factor-related accidents and occupational injuries.

Initiatives with Contractor Companies

At ENEOS refineries and other facilities, when selecting contractor companies, we evaluate the companies’ safety management in their business operations. In addition, even after beginning business relationships with contractor companies, we conduct regular evaluations of the status of their safety management, identify areas for improvement and follow up on the implementation of improvement measures.
Moreover, in order to ensure proper safety management of contractor companies, we require the primary contractor to submit and execute a safety management plan, establish KPIs for the contractor company, conduct regular monitoring and evaluation, and report on improvements.
All new entrants to contractor companies are given orientation training.

Main Initiatives at Refineries and Plants for Earthquakes

The ENEOS Group implements various earthquake measures at its refineries and plants.

Measures to Protect Lives

Elevated warehouse (Sakai Refinery)

As a precaution against earthquakes and tsunamis, we have voluntarily implemented seismic reinforcement of our onsite offices and production unit control rooms, with priority given to the protection of human life.
We have also designated locations and methods for evacuation in case of an earthquake or tsunami, and we carry out disaster preparedness drills every year.

Measures for Seismic Reinforcement of Facilities

Brace retrofitting on a spherical tank

We are carrying out legally required seismic reinforcement work for tanks that store hazardous materials.
Upgrade work on floating-roof tanks subject to this requirement was completed before the statutory deadline. As for internal floating-roof tanks, which became subject to legislation in fiscal 2011, plans are in place to complete seismic reinforcement work by the statutory deadline (end of fiscal 2023).
For high-pressure gas facilities, we have already completed seismic assessments following government instructions, as well as the retrofitting of spherical tanks with braces to increase earthquake resistance, taking into account the effects of the Great East Japan Earthquake. Seismic countermeasures for facilities of high importance were completed in fiscal 2021, marking the
completion of our seismic reinforcement of high-pressure gas facilities.

Measures to Mitigate Damage from Disasters

We have installed seismographs at all of our refineries and plants as part of a system that automatically shuts down equipment in a prompt and safe manner in the event of an earthquake, depending on the intensity.

Countermeasures against Accidents and Malfunctions

Disaster Prevention Facilities

High-capacity foam water canon (Oita Refinery)

At our refineries, plants, and stockpiling terminals, we have established self-defensive organizations for disaster prevention and installed necessary disaster response equipment and facilities in preparation for potential accidents and disasters. We have also established a defensive organization for cooperative disaster prevention with nearby companies to improve the disaster preparedness of industrial complexes.

Oil Spill Countermeasures

Drill for oil spill at sea using oil fences and oil recovery vessels
(ENEOS Kiire Terminal)

We have multiple oil dikes surrounding our storage tanks and systems to prevent leakage from spreading offsite. In addition, to promptly respond to oil spills at sea, we have oil fences to prevent oil spills from spreading and oil recovery vessels in place.

Fire Countermeasures

High-altitude chemical water cannon vehicles (Mizushima Refinery)

We have equipped our refineries and plants with fire extinguishing equipment, such as large chemical firefighting vehicles, high-altitude water cannon vehicles, and high-capacity foam water cannon systems, for response in the event of a major fire.
Our facilities also have disaster response vessels with firefighting capabilities to respond to fires at sea.

Disaster Drills

Comprehensive disaster response drill with refinery self-defensive organization for disaster prevention and local government (Sendai Refinery)

We regularly implement comprehensive disaster response drills for our self-defensive organizations for disaster prevention to ensure that we can respond in a quick and agile manner should an actual disaster occur. We also hold other drills, including joint disaster preparedness drills involving local fire departments as well as disaster response organizations from nearby companies and local communities.

Ensuring a Stable Supply

The ENEOS Group has established a backup system for ensuring a stable supply in the event of a major disaster that impacts the functions of production and shipping sites through collaboration with other production and shipping sites. We also conduct drills and training regularly to ensure that our sites can continue to function in the event of a disaster.
