Security control system

Shikoku Operations is reinforcing its own security system by creating a "security control system" in accordance with the High Pressure Gas Safety Act and establishing the Shikoku Operations' Policy.

Shikoku Operations Obtains Class B Certification under the High Pressure Gas Safety Act

As of September 1, 2025, Shikoku Operations was certified by the Minister of Economy, Trade and Industry as an Accredited Advanced Safety Provider (commonly referred to as "Class B Certification") under the High Pressure Gas Safety Act.
This certification is granted to operators that satisfy the new certification criteria, including strong commitment to safety by top management, robust compliance systems, the use of advanced communication technologies, risk management, and cybersecurity measures, and that are capable of maintaining an advanced level of safety under the High Pressure Gas Safety Act.
We will continue to strengthen our safety capabilities through these initiatives and fulfill our social responsibility as an energy company by ensuring the stable supply of petroleum products.

Safety Capability Assessment by an Independent Third-Party Organization

In FY2023, Shikoku Operations underwent a safety capability assessment conducted by the Japan Industrial Safety Competency Center (JSCC), a specified non-profit organization. The safety capability assessment is based on an evaluation methodology developed by the Japan Society for Safety Engineering (JSSE) and uses a five-level rating system to assess 17 elements covering the safety foundation and safety culture that support operational safety.
As a result, the average scores for both the safety foundation and safety culture were evaluated as exceeding the standard level for the petroleum and petrochemical industry.
At the same time, the assessment also identified new challenges. We will continue to pursue continuous improvement through our safety management activities and further enhance our safety capabilities.

Shikoku Operations has established an industrial safety and health management system and is ISO45001 certified. We are working towards systemic and continuous industrial safety and health improvement by performing the PDCA (Plan > Do > Check > Action) cycle according to Shikoku Operations' Policy.
