Occupational safety

The Idemitsu Group strives to reduce and eliminate risks and eliminate accidents and disasters through the appropriate allocation of management Resources and the maintenance, management, and improvement of equipment, processes, and work systems, in order to ensure the safety of people as our top priority. Our philosophy for ensuring safety is ''We strive to foster a culture of safety.'' Ensuring safety based on this philosophy is the result of management efforts, and zero accidents and disasters is the greatest achievement in this field. Based on this recognition, we place the utmost importance and priority on ensuring safety in all business activities such as production, logistics, sales, research and development, all business operations, and various value judgment standards in each scene and stage of every action. We have established the following specific policies and strive to ensure the health, safety, and security of all people associated with our company.

Our group positions safety, health and the environment as the foundation of management, and has established a Safety and Environment Headquarters to promote these initiatives.
Every year, each department and major affiliated company independently runs the PDCA cycle based on the year's basic policy and priority issues presented by the headquarters. Each department and major affiliated company appoints a safety and environment officer to manage and promote overall initiatives, including those at Complex under their jurisdiction.
The secretariat determines the frequency of audits according to safety and environmental risks and management status, and conducts audits. If improvements are found through the audit, the secretariat will follow up on the response plan from decision to completion.
The Safety and Environment Headquarters Director and Deputy Heads visit the site every year to provide safety and environment guidance and patrols. Additionally, in order to prevent large-scale accidents at Complex, we have established a Safety and Security Advisory Committee that includes outside experts, and are working to develop more effective safety and security measures.

●Position of the Safety and Environment Headquarters in the corporate governance system and safety and environment management system

Utilizing the safety and health know-how cultivated through our past experience, we have built and operated a unique management system based on the international standard for occupational safety and health management systems (ISO45001) and the certification standards of the High Pressure Gas Safety Act. doing. We also make continuous improvements through internal audits and management reviews.
Some of our overseas Complex have obtained ISO45001 certification. Additionally, all of our group's Refineries/Complexes, and refining companies have obtained certification under the High Pressure Gas Safety Act.

Reflecting new thinking on earthquake countermeasures such as strengthening facility structures, which we have implemented since FY2005, we have revised the "Natural Disaster Risk Management Guidelines" in FY2021, adding measures against storm surges and typhoons to earthquake countermeasures. . In fiscal 2022, we proceeded with consideration of specific issues based on these guidelines.

Preventing the recurrence of fatal accidents

In fiscal 2022, we set the goal of ''no accidents'' and aimed for ''zero serious personal accidents,'' including fatal accidents, but one fatal accident occurred. During a complete remodeling of a group company's self-service station, one partner company employee died due to an electric shock. Although this work was being carried out under a contract, we worked with the main contractor to investigate the cause, shared the case study within our group, and thoroughly informed everyone about measures to prevent recurrence.
As a measure to prevent the recurrence of similar accidents, we have reconfirmed and ensured that hazardous areas on the premises are clearly marked and measures to prohibit entry are in place at each Complex within the group.

Accident-free efforts

In fiscal 2023, we will continue our "challenge to achieve no accidents," work to establish a culture that thoroughly adheres to the "rules to protect lives," and ensure that workers are protected during irregular operations and work. We are strengthening our focus on identifying and responding to danger sources. Specifically, we have started a company-wide case review meeting for cases that could have resulted in serious personal injury accidents, in an effort to eliminate serious personal injury accidents.
In addition, while each department and major affiliated company independently promotes the PDCA cycle for safety and environmental management, we are ensuring safe and stable operation by comprehensively discovering potential hazards, including processes and equipment, and taking appropriate risk assessment measures. We are working to continue.

Strengthening the earthquake resistance of existing facilities

Our group's Refineries/Complexes have traditionally been working to strengthen their response in preparation for natural disasters. Regarding earthquakes, we have evaluated the seismic resistance of equipment and other equipment based on the assumed earthquake strength stipulated by law, and have taken steps to strengthen them as necessary. Furthermore, based on the lessons learned from the Tokachi-Oki Earthquake, we have evaluated and made improvements to simulated earthquake intensities that exceed legal standards.
In response to the Great East Japan Earthquake in 2011, laws and regulations regarding high-pressure gas equipment were strengthened and standards were reviewed. In line with this, we are carrying out planned reinforcement work on the spherical tanks that store LPG at our group's Refineries/Complexes, with the aim of improving the earthquake resistance of the support structures. Since fiscal 2020, we have been working to strengthen equipment at Refineries/Complexes, and oil terminal using the Resilience Assistance Project. Our group will continue to consider and implement further earthquake resistance enhancements.

Super certified Complex

Our group's Refineries/Complexes are working to improve their safety capabilities in light of the increasing sophistication of safety technology, including the use of advanced technology, advanced risk assessments, and advanced education and training. As a result, the following Refineries/Complexes Complex been certified as "Super Certified Businesses" that are implementing advanced safety initiatives under the High Pressure Gas Safety Act.

In order to cope with the aging of plants and the decrease in the number of skilled employees, Complex that implement advanced safety initiatives such as the use of IoT and big data are certified as "Super Certified Complex" and are recognized as industrial It is expected that this will also contribute to improving the security capabilities of the entire industry. For certified Complex, rationalization of voluntary safety regulations will be applied, leading to stronger international competitiveness.

Practical firefighting training

[Training of disaster prevention personnel at Refineries/Complexes]

In the unlikely event that a fire or explosion occurs, it is extremely important to carry out initial fire extinguishing activities and take measures to prevent the spread of fire in order to minimize damage inside and outside Refineries/Complexes. Therefore, we are focusing on training disaster prevention personnel, recognizing the importance of accumulating practical training based on basic fire prevention theory. For example, we learn the basics of disaster prevention activities through classroom lectures, and then carry out training in handling materials and equipment and deploying hoses according to a plan. In particular, at Hokkaido Refinery, Chiba Complex, and Aichi Complex, we also conduct flame-contact training using live fire training areas.

[Live fire training at Niigata Disaster Prevention Training Center]

The Safety, Environment and Quality Assurance Department owns the Niigata Disaster Prevention Training Center, and we continue to accept a large number of trainees from within the company as well as from companies in the industry every year. The training assumes fires that occur in different types of equipment at Complex, and by learning initial fire extinguishing methods suitable for the nature of oil fires through theory (lectures) and practice (Complex fire training), We are working to strengthen our initial fire extinguishing system.

Utilization of external education

[Training for top management]

In order to prevent serious industrial accidents, it is extremely important that top management at the site, such as Refinery and Complex, have a strong awareness of safety and promote accident prevention measures under their strong leadership. is. Therefore, related organizations in the petroleum and chemical industries and related companies, including our company, appealed to an external training center about the importance of fostering safety awareness among top management. This was the starting point for the center's special lecture, ''Future Safety and the Role of Top Management,'' which has been held regularly since March 2016. At our company, on-site Refinery and Complex as well as top executives from the head office's Manufacturing & Technology Department attend this course every year, and together with Refinery from other companies, mainly from companies around the center, lead the way in industrial safety. We are working to strengthen this.
