Personal Safety Management ^{GRI 403-2, GRI 403-5}

To control, prevent, and reduce the risks of accidents that directly impact PTT employees and contractors, PTT places a high priority on enhancing its safety, occupational health, and work environment management systems. This also includes fostering a robust safety culture throughout the organization, with a focus on employee and contractor engagement to promote safety awareness and behaviors both during and outside of working hours. Key actions include:

• Establishing comprehensive risk management and control processes for safety, occupational health, and work environment. This encompasses hazard identification, risk assessment, the development of risk control measures, and the implementation of mitigation strategies. These processes are formalized into operational procedures, work practices, and standards that meet international practices.
• Promoting SSHE culture development. A clear and structured process has been developed for cultivating a strong SSHE culture within the organization. Periodic surveys are conducted to evaluate the level of SSHE culture, with the results used to continuously refine and enhance operations.
• Developing video materials and brochures on PTT’s basic safety rules (PTT Life Saving Rules). This includes a review of the operational procedures aligned with PTT's Basic Safety Rules to ensure effective communication and understanding among employees and contractors. Training sessions are organized to promote safe working practices, reduce risks, and prevent accidents and injuries. Special focus is placed on controlling on-site operations, including key processes such as work permits, energy isolation, confined space work, working at heights, use of personal protective equipment (PPE), lifting and handling of objects, and chemical management. Furthermore, employees and contractors are granted theRight to Refuse Work if they find tasks unsafe, with no repercussions. Employees are also given Stop Work Authority to halt any work that may present a safety risk.
• Implementing an incident and non-compliance reporting system. A robust system has been established for employees to report incidents, accidents, near misses, substandard practices or conditions, and any violations of legal requirements, regulations, or operational procedures. The ongoing collection and analysis of this data enable the identification of corrective measures and the development of systematic strategies to control and mitigate risks.
• Providing mandatory and need-based safety training. PTT offers safety training, both mandated by law and based on specific training needs, to all employees and contractors.
• Continuously promoting and developing a safety culture. PTT has launched the Incident and Injury Free (IIF) program at the Rayong and Khanom Natural Gas Separation Plants, focusing on integrating the IIF 5-Step problem-solving process: planning, risk assessment, employee engagement, skill-building, and sustainable implementation. This initiative has been expanded to the Natural Gas Pipeline Division, further reinforcing safety awareness and behaviors. All operational areas are required to enhance safety through Small Group Activities (SGA), which has led to an improvement in the safety culture score from 4.36 to 4.49 (out of 5) and a record of zero severe accidents. Additionally, training has been provided to reinforce safety knowledge and behavior among workers at 9 major gas distribution stations (Mother Stations), with a total of 234 participants. PTT is committed to continually improving and expanding the safety culture across the organization

Occupational Health and Working Environment Management

In managing occupational health and the working environment, PTT has developed the PTT Group Occupational Health Management System and formulated the PTT Group Occupational Health Management System Guideline. These frameworks are in compliance with legal requirements, best practices, and international standards. Key initiatives include:

• Engaging Occupational Medicine Specialists to review and update the Health Risk Assessment (HRA) process, ensuring it comprehensively addresses all major hazards such as physical, chemical, and biological threats. This includes environmental assessments, health screening programs, sampling methods, and sample handling procedures. Additionally, control measures are implemented to mitigate health risks, with mandatory annual occupational health check-ups for all employees.
• Providing Specialized Occupational Health and Safety Training to employees, which includes: Hearing Conservation Programs to educate employees on preventing hearing damage caused by workplace noise exposure, Ergonomics Training for employees in office environments and operational areas, focusing on computer usage and manual material handling. These training sessions are designed to identify and address ergonomic issues, and operational guidelines are established to align with international ergonomic standards.
• Developing and Updating Operational Guidelines for occupational health, including ergonomics for computer work, manual material handling, and medical emergency response procedures. These guidelines aim to enhance the overall management of occupational health within PTT and its subsidiaries, aligned with the Health Performance Indicators (HPI) as per IOGP standards.

Process Safety Management (PSM)^{GRI 403-2, 403-7}

Accidents within the production process can cause significant damage to life, property, and the environment, with far-reaching effects on stakeholders across the entire supply chain. To mitigate these risks, the PTT Group places a strong emphasis on preventing major incidents such as fires, explosions, or the release of hazardous chemicals into the environment. This is achieved through the implementation of a robust “Process Safety Management (PSM)” system across key operational areas. The PSM system ensures that production processes and plant construction are designed and built in accordance with sound engineering principles and international standards. Employees are trained to operate machinery safely according to established operational manuals, while machinery and equipment are regularly maintained and inspected to meet international standards.

PTT Group has established both leading and lagging indicators for process safety, following internationally recognized standards such as API RP 754. These indicators are incorporated into the Company’s annual QSHE targets. Lagging indicators, such as Process Safety Events (Tier 1 and 2), are consistently monitored and reported. This allows for the timely implementation of corrective and preventive measures to address and minimize the risks of production-related incidents, ensuring a proactive approach to process safety.

PTT Group has been applying Bow Tie Analysis techniques and Barrier Validation for Major Accident Events (MAE) since 2019 to systematically analyze and manage process safety risks. This is aimed at preventing and controlling major accidents within operational areas. The Barrier Validation process ensures that the control measures for MAE in the operational risk management system are both effective and in optimal condition, ready for deployment. These control measures include both equipment barriers and human barriers. Should any deficiencies be found in these control measures, they are promptly addressed and corrected to restore their full functionality. Effective and operational control measures for MAE play a crucial role in preventing severe accidents, minimizing production downtime, and ensuring the continuity of business operations. Moreover, these measures help reduce potential impacts on surrounding communities and the environment. In 2024, the PTT Group expanded the application of Bow Tie Analysis to two additional operational areas: the Wangnoi Compressor Station (WCS) and the Sriracha Oil Depot. As a result, all high-risk operational areas across PTT now fully implement Bow Tie Analysis, ensuring comprehensive risk management. The next phase of this initiative involves reviewing and updating the risk data to ensure it remains current, while maintaining the readiness of control measures for ongoing effectiveness. In addition, Barrier Validation was extended to the Ratchaburi Compressor Station (RCS) in 2024. This essential process ensures the thorough verification of both equipment and human control measures, while also promoting the continuous improvement and elevation of process safety standards across PTT and its subsidiaries. These efforts significantly contribute to the prevention of severe accidents, such as fires, explosions, and hazardous chemical leaks. PTT organized workshops to share knowledge and best practices among companies, ensuring the effective implementation and elevation of process safety standards throughout PTT and PTT Group's operational areas.

Additionally, PTT has expanded its Asset Integrity assessments within its operational areas under the PTT Safety Risk Assessment and Assurance program in 2024. This extension covers an additional nine operational areas, helping to further raise operational safety standards across the organization.

Security Management

PTT has established security management standards for PTT Group, along with risk assessment guidelines to evaluate security threats across the organization. The Company has also developed procedures for safeguarding personnel and assets, ensuring a consistent and unified approach to security across all operational areas of PTT and PTT Group. These guidelines are regularly reviewed to stay aligned with changing circumstances and emerging risks. Additionally, PTT collaborates with a network of government agencies, state enterprises, and private sector partners to enhance intelligence operations and ensure swift assistance during emergencies. Regular security and emergency response drills are conducted across PTT Group’s operational sites, ensuring preparedness and the ability to manage emergencies in a systematic and efficient manner.

PTT places significant emphasis on enhancing its security management capabilities, focusing on three key areas: building personnel competencies, refining operational protocols, and integrating innovative security technologies into operations.

Aware of the potential human rights risks associated with security operations, PTT has clearly defined measures to respect human rights within its Quality, Security, Safety, Occupational Health, and Environment (QSHE) policy. This policy ensures the protection of life, property, and sensitive organizational data. It also mandates that security personnel undergo training in self-defense, personal search techniques, and other related skills. Furthermore, PTT conducts thorough evaluations of security personnel to ensure they understand their roles and responsibilities and operate without infringing on individuals' rights. These policies extend to all security service providers across PTT’s operational areas, with mandatory compliance audits conducted every three years. In response to increasing threats, PTT has also developed a collaborative network for intelligence sharing, allowing for rapid threat assessments. The Company has conducted threat evaluations for PTT and its subsidiaries in three high-risk areas as follows:

1. Southern Region: The three southern border provinces.

2. Western Region: Specifically in the Thai-Myanmar border area.

3. Eastern Region: Chonburi Province and Rayong Province.

In collaboration with external agencies, PTT, together with the National Security Council and its partner networks, organizes the Critical Infrastructure Security (CI-SEC) Academic Conference. This event is designed to strengthen and promote the security of the nation’s critical infrastructure, fostering resilience and advancing best practices in infrastructure protection.
