Furthermore, PTT also emphasizes on continuous development of security management in order to reduce the risk of threat that may happen in various forms. Such risks may cause significant damages to the business and employees’ safety.

PTT has continuously developed and applied tools per different standards. The emphasis is on building safety behaviours through reporting system for incidents, accidents, near misses, sub-standard act/conditions on the Intranet system. The system can record incidents, analyse and investigate for true cause. PTT also develops mitigation measures and prevention online, as well as disseminating information internally to prevent recurrence in the future.

Employees’ Safety 

PTT promotes awareness of employees and subcontractors, specifically to instil safety behaviours. This was achieved through diverse training for all employees and subcontractors. There are Incident Injury Free (IIF) of Natural Gas Separator, which is one of the successful projects in 2018. The project uses integrated management process according to the 5-step IIF principle. 
  • Planning

  • Skills
  • Sustaining

PTT formulates management approach to promote PTT Group’s safety and occupational health culture. The approach specifies process and steps for corporate SSHE culture development with clarity.

PTT gives great attention to PTT Group Occupational Health Management System, whose system is in accordance to international standards. It serves as a guideline in occupational health management. Furthermore, PTT also developed proactive occupational health performance indicator, which is called ‘Health Performance Indicators (HPI)'. The indicator helps users understand occupational health performance. There are also efforts to elevate work’s efficiency continuously. In order to enhance employees’ and operators’ understanding, PTT has also develop a multiple occupational health manual/guideline to disseminate information on occupational health. This helps improve occupational health management’s effectiveness continuously.

Health Risk Assessment is one of the tool used to assess potential health impacts that may occur to PTT’s employees and operators, due to contact or expose to other risks at work. There are also measures to control and decrease health risk level, as well as annual health check-up organized. This was delivered in tandem with knowledge-sharing measures to employees prior to worksite entry. In some cases, there are risks in which operators are expose to hazardous chemicals. For such, PTT has developed monitoring of work environment; established work duration, and mandated for workers to wear appropriate protective equipment. Additionally, there is also continuous health promotion projects to encourage employees and subcontractors to have good health. 

Process Safety Management

Process safety accidents can cause damages to life, assets and environment, widespread and severe. It can also affect stakeholders throughout the entire supply chain. Therefore, PTT Group focuses on preventing severe accidents, such as fires, explorations, hazardous chemical contamination. The Group uses Process Safety Management (PSM), focusing on accurate process safety design and plant construction design per engineering principles and international standards; while ensuring operators can operate machines according to operation manual. Machines and equipment must be maintained regularly according to international standards. PTT Group has set targets for process safety event tier 1 to be 0 by 2021.

PSM System is communicated via PTT Integrated Management System (PIMS) and Operational Excellence Management System (OEMS). The system connects to lead responsible function, which are Engineering, Operation, Maintenance and SSHE. The roles and responsibilities are divided according to related management topics.

PTT Group manages process safety strictly. PTT Group Process Safety Management Task Force is a network of PTT Group’s executive and employees, driving for collaboration, and exchange of knowledge. Continuous sharing includes in-depth technical knowledge for safety process control, learning from past lessons and mistakes that cause damaging incidents. Case studies may come from PTT Group or global industries. The information is used to formulate effective and comprehensive prevention measures, which are good practices and recommendations from relevant assessments. Furthermore, in 2019, PTT Group started deploying Bow Tie Analysis tools to analyze and manage process safety risk. The aim is to prevent and minimize severe accidents within PTT Group’s operation sites. PTT analyzes and invests efforts to understand risks in processes; formulates prevention and impact mitigation measures. PTT also monitors effectiveness of deployed measures regularly, with the aim to expand coverage across entire PTT group in 4 years.

PTT Group has established collection of PTT Group’s process safety indicators, consists of Process Safety Leading and Lagging Indicators. The indicators reference international standards of data collection, API RP 754, in order to promptly prevent losses. Process safety event tier 1 and 2 indicators are communicated to relevant parties, as PTT Group’s annual QSHE targets.


PTT formulates PTT Group’s Security and Safety Management Standards and Risk Assessment. They serve as framework for security and safety governance, ensuring consistency across the organization.
