Management Approach

At PTT’s workplace, safety comes first. To ensure the workplace conditions comply with international occupational health and safety standards at all operating areas, all of PTT Group’s important operational areas have been certified using Occupational Health, Safety and Environmental Management System Certification against TIS/OHSAS 18001. The operational areas have been continually awarded outstanding workplace for Occupational Health, Safety and Environment. Safety principles are applied using tools and methods including an intranet reporting system. The intranet reporting system captures accidents, near-miss, environmental conditions and below standard actions. Each incidence is recorded, analysed, investigated and appropriated corrective actions and protection plans are prepared. The online database can be accessed by all staff; best practice and lessons learned are shared internally with the aim to prevent similar incidents or near misses in the future.

Employee Safety and Well-being

At PTT, there is an emphasis on creating safety awareness amongst employees and contractors. In order to foster safe behaviour, various programs have been implemented i.e. Incident Injury Free (IIF) program at the gas separation units. IIF started in 2016 and is considered as one of PTT’s flagship projects. The IIF project has an integrated process that follows five principles

  1. Planning
  2. Assessment
  3. Engagement
  4. Skills
  5. Sustaining


PTT has provided its employees and contractors with training as part of PTT’s basic safety culture on the basics of Occupational Safety and on the principles of PTT’s safety event reporting system. For continuous improvement, PTT Group developed the SSHE Culture Management Guideline which outlines the development process of organizational SSHE culture.

Implementation and deployment of safety aspects is the responsibility of the operating officers for occupational health and safety. PTT prioritizes development of PTT’s OHS management system to comply with international standards. The PTT’s OHS KPIs are referred to as Health Leading Performance Indicators (HPI) and are designed to be the proactive KPIs which continuously enhance PTT’s OHS performance. To share and disseminate OHS knowledge and best practice, PTT has developed working manuals and procedures which are shared with officers and operators to use as reference guides for efficient and safe working conditions.

Health Risk Assessment is one of the tools to determine health aspects and impacts for PTT’s operational areas. The assessment considers risks from direct contact with harmful substances or other working related risk factors. Based on the risk assessment PTT puts in place control and appropriated mitigation measures, for example, annual health check-up, knowledge sharing and trains sessions. For employees working in areas that pose a risk of contact with dangerous chemicals, PTT will conduct an evaluation of the work environment and assess risks of contact with dangerous chemicals. Workplace exposure limits for dangerous chemicals haven been determined and all operators must wear appropriate PPE. In addition health promoting campaigns are held in operating areas to support employee health and well-being.

Process Safety Management

PTT Group has committed to a target of zero Tier 1 Process Safety Events. PTT Group strictly manages process safety through the process safety working group which was formed to create a network of PTT Group management and employees capable of driving mutual collaboration and information exchange on technical approaches for process safety control, and to share lesson learned from incidents in PTT Group and Oil and Gas sector.

Any accidents occurring in the production line can have impacts to life, asset, and environment, and affect stakeholders’ trust in the value chain. PTT Group has the Process Safety Management (PSM) in place to ensure appropriate design, operation and maintenance and to prevent accidents.

Operating results from the PSM system are communicated via the Operational Excellence Management System (OEMS) to the main units i.e. Engineering, Operation, Maintenance, and SSHE. These units are part of a forum that is responsible to ensure compliance with OEMS elements.

Recently, PTT Group PSM Implementation Guideline and Audit Checklist have been prepared and these manuals are shared with relevant OEMS Forums. These manual are for internal purpose to up-scale Process Safety Barrier i.e. Operating Window, Management of Change, Pre Start up Safety Review (PSSR), and Safety Critical Equipment, etc. The system can be used for consolidation and analyse of information for future improvement.

The expansion scope of monitoring indicators covers Process Safety Indicator of Tier 3 and 4 that enable PTT to proactive monitor and sustain proactive prevention. The expanded scope has been communicated to relevant parties via the OEMS Forum and implementation against targets is monitored.


PTT has established PTT Group Security Management as well as guidance for PTT group security risk assessment for setting up performance monitoring framework to ensure security aspect is consistent throughout PTT and PTT Group. In 2011, PTT Way of Conduct was issued which is part of personnel job responsibilities is being followed by PTT group. Central operators are responsible for evaluating job performance to be in accordance with PTT group security risk assessment manual. The output from assessment and appeals for security and safety issues are analyzed and used in order to improve successively security management system. PTT collaborates with government agencies for timely warning and emergency notifications in case of an emergency. Security practice training is regularly performed in all PTT sites, together with emergency practice training for personnel to prepare and effectively cope with emergency situations.

PTT is concerned about human right issues arising from security. Hence, PTT has addressed human right regulation including quality, security, health, and environment policies to be followed. The regulations cover life, property, and data protection, as well as organizing training courses, such as martial art and people frisking skills, for PTT security personnel and included in one of the requirement for employment. Evaluation of security personnel performance is regularly monitored through security assessment of PTT group for assuring that all security personnel recognize their right in performing their job duty in which do not abuse ignore or deny basic human rights.

Although PTT is currently not a participant of the Voluntary Principles on Security and Human Rights, PTT operates by endorsing accordingly to the Principles which align to PTT Group Security Management Standard.
