Basic Approach

As a corporate group responsible for the stable supply of energy, resources 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.
In addition, based on the above, each Group company assesses risks pertaining to occupational safety and establishes its own safety policy in accordance with its own business characteristics, 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 partner companies also participate, and we have established preventive and emergency measures to cope with all manner of accidents, problems and natural disasters.

The ENEOS Group Environment & Safety Committee, chaired by the officer (director) responsible for the Safety, Health & Environment Department at ENEOS Holdings, has been established under the ENEOS Group CSR Council, which is chaired by the president of ENEOS Holdings.
The Committee evaluates and shares information on occupational injuries and the implementation of safety activities at each Group company, and also reviews and implements measures to prevent occupational injuries.
For information on our structure, see the ENEOS Group Environmental Management Promotion Structure.

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 its refineries and plants.
JX Nippon Oil & Gas Exploration has adopted its own HSE1 management system (HSEMS), which conforms to ISO standards.
Through HSEMS systems management, the company has established an integrated safe operations framework that includes overseas business sites.
At JX Nippon Mining & Metals, 12 business sites in Japan have obtained OHSAS 180012 certification, and operate this management system to promote safety management. The company is now working to switch this certification to international standards (ISO) by March 2021.

Safety Activities

At the ENEOS Group Safety Education Center (Hitachi City, Ibaraki Prefecture), the ENEOS Group works to improve employee sensitivity to risks. Group companies are also working individually to raise safety awareness and enhance safety management.
Every year in July, ENEOS releases a video message on safety by its president to demonstrate 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). Among these activities, the STOP1 card and safety activities known as UCUX2 dictate that if an unsafe behavior is found during a work task, the work task will be suspended temporarily and cannot be restarted until an improvement proposal is made and the unsafe element is remedied. These activities enable anyone who notices an unsafe situation to propose improvements, which encourages frontline workers to become actively involved in safety and improves overall safety awareness.
JX Nippon Mining & Metals is working continuously to improve safety awareness and sensitivity to risks, by such means as introducing hazard simulation equipment at each business site, preparing and implementing safety curriculum based on past accidents (videos re-enacting occupational accidents), and holding safety lectures led by outside instructors.

Building a Mutual Assistance System for Refineries and Other Sites

For response in the event that a refinery sustains damage from an earthquake and is unable to regain control unaided, ENEOS has established a system for emergency response operations and measures to enable organized support from within the Group. This system ensures the execution of a swift and agile response.

Results of Major Initiatives for Ensuring Safety

With the goal of eliminating all serious occupational injuries,* the ENEOS Group conducts extensive safety activities and safety training programs, in which employees from its partner companies also participate.
In fiscal 2018, there were a total of 40 occupational injuries, four more than the previous fiscal year. However, there were no fatal occupational injuries of contractor company workers, for which there was one each for two consecutive years in fiscal 2016 and fiscal 2017. 20 directly hired employees sustained occupational injuries, an increase of 11 from the previous fiscal year.
The occupational injury frequency rate (the number of occupational fatalities and injuries per million working hours) and the occupational injury severity rate (the number of lost working days per thousand working hours) were both significantly below the average for all industries (Ministry of Health, Labour and Welfare survey).
In fiscal 2017, we adopted Group-wide safety efforts for occupational injuries that occur with greater frequency or which are likely to lead to serious occupational injuries, and are making further efforts to prevent their occurrence.
As a main initiative for fiscal 2018, we collected and shared information on the Group companies' initiatives to address mutual safety items, including safety education, important rules, and supervision and monitoring systems.

Safety Training Program Using Virtual Reality

In 2013, the ENEOS Group established the ENEOS Group Safety Education Center in Hitachi City, Ibaraki Prefecture. Established to enable workers to experience the risks inherent in their work, the aim of the facility is to raise the safety awareness of individual employees through simulation training.
In fiscal 2018, 1,538 employees participated in training at the facility, bringing the total number since the center opened to 10,005.
In addition, a new Group training program that utilizes virtual reality (VR) technology was launched in September 2017. Since then, the program has been expanded to include a larger number of VR experiences. This program enables workers to feel what it is like to be personally involved in an accident and think about victims' psychological state, as well as accident causes and preventive measures. Using VR technology, participants can experience accidents that cannot be safely replicated in the real world, such as steam explosions, being struck by heavy machinery, entanglement in high-speed rotors, and falling from high places, from a victim's perspective, thereby increasing the effectiveness of the training. Since its introduction, VR experiences with dispersal of liquid chemicals, getting fingers caught in slings, grinder recoil, and falling down stairs have been added to the program, further enhancing the training.
Our production sites are also equipped with hazard simulation equipment, and workers are required to undergo training using this equipment before they can begin actual work. Through these and other efforts, we are working to ensure safety across the entire Group.

Preventing Collisions Between Heavy Machinery and People

Test in progress at the Saganoseki Smelter & Refinery

The JX Nippon Mining & Metals Group considers the prevention of collisions between heavy machinery and people as a key safety issue. This is because there is a high risk of collisions on the manufacturing floor, where heavy machinery, such as forklifts, is used, increasing the potential for serious accidents.
The company has implemented a number of countermeasures at workplaces to prevent collisions, including demarcation of separate routes for heavy machinery and people.
Since 2017, the introduction of measures that go a step beyond conventional approaches, making the use of the latest preventive safety technologies, has been under consideration.
From fiscal 2017 to fiscal 2018, a system for automatically braking heavy machinery was tested at the Saganoseki Smelter & Refinery of JX Mining & Metals Group company Pan Pacific Copper, while a system that issues warnings and commands to both operators and workers was tested at JX Nippon Coil Center. Based on the test results, these solutions were introduced at both business sites and put into operation in 2018.

Acquisition of Super Certification for High Pressure Gas

ENEOS's Kawasaki Refinery and Sakai Refinery were the first and second businesses to be certified under the new certification regime for the High Pressure Gas Safety Act in fiscal 2017. Mizushima Refinery A and B also obtained certification in August 2019.
This certification, established by Japan's Ministry of Economy, Trade and Industry, is awarded to refineries that satisfy certain criteria for such areas as advanced safety activities and operational support systems. As a certified business, we will continue to implement high-quality safety activities with the goal of improving our safety practices even further.

Initiatives at Refineries and Plants for Major 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 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 training every year.

Measures for Seismic Reinforcement of Facilities

Brace retrofitting on a spherical tank

We are moving forward with 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).
As for high-pressure gas facilities, we have carried out seismic performance evaluations based on administrative directives, and we have completed the retrofitting of spherical tanks with braces to increase earthquake resistance, taking into account the effects of the Great East Japan Earthquake. We continue to carry out earthquake resistance measures on critical facilities, with completion of work planned for the end of fiscal 2021.

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.

Major Initiatives to Prepare for Accidents and Problems

Disaster Prevention Facilities

At our refineries, plants and stockpiling terminals, we have taken measures such as the installation of disaster prevention equipment and facilities in preparation for potential accidents and disasters.

Oil Spill Countermeasures

Deploying an oil fence as part of a drill to help prevent marine pollution

We are able to respond quickly to oil leaks on land or at sea. We have multiple oil dikes surrounding our storage tanks and systems to prevent leaks from spreading offsite. We also have oil fences and oil recovery vessels in place to respond to oil leaks at sea.

Fire Countermeasures

Firefighting vehicles

In addition to large ladder trucks with hazardous material response capabilities, compressed air foam system (CAFS) tankers and high-capacity water cannons, numerous foam extinguishing systems, sprinkler systems and large extinguishers have been placed onsite for response in the unlikely event of a major fire.
Our facilities also have disaster response vessels with firefighting capabilities to respond to accidents or disasters at sea.

Disaster Drills

We regularly implement comprehensive disaster drills for our own disaster response organizations 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 and disaster response organizations from nearby companies.
