Employee and Contractor Health and Safety Management 

   Thaioil Group’s occupational health and safety management system is governed by the Thaioil Group Policy on Quality, Security, Safety, Occupational Health, Environment, Energy, and CSR Policy (QSHE) and the TOP Group QSHE Excellence 2019 – 2023 strategy. Both the policy and strategy drive the Company in building organizational capacity to sustainably and continuously achieve excellence in QSHE.

   Thaioil currently follows the strategic plan for business excellence (House of Business Excellence: O2Bx) to prepare organizational readiness in becoming a world class refinery by 2022. Safety is one of the pillars of this strategy that has been prioritized for development and improvement.

   In addition, Thaioil Group takes a proactive strategy to promote safety. For example, building on the management walk and talk activity, Thaioil Group started organizing “GEMBA Walks”, which directly involve management executives. In this activity, management executives inspect operations through conversing with operational staff on their key activities with questions are designed to be specific and build understanding. For high risk activities, recommendations are shared on maintaining both personal and process safety. Moreover, Thaioil has also continued to implement the QSHE Roll Out activity, which focuses on engaging operators and instilling cautiousness regarding quality, security, safety, and environment. In this way, we ensure that we are involving all operators across every operational area. Thaioil Group has also applied appropriate management systems to sustainably develop our activities. Furthermore, the performance of such activities are regularly reported to the management and jointly discussed to identify corrective actions needed. In addition, a management review process is implemented on an annual basis to determine improvement areas and develop work plans for the following year. The process has been consistently communicated to employees to ensure effective practices.


OHS Programs

In 2021, The Company implemented key occupational health and safety activities as follows:  

  • • To ensure that the organizational safety culture starts from the top of the organization, the Board of Directors requested that management executives regularly present case studies and key issues on safety during the Board monthly meetings. These case studies and key issues may come from within the Company or externally, but should serve to promote continuous development in the safety measures of the Company.
  • • The onsite visit by the President and Chief Executive Officer and management executives during normal operating conditions, maintenance downtime, and construction periods. These visits help build employee morale, reaffirm the Company’s commitment to maintaining safe working conditions, and set a good example of safety leadership.
  • • Updated the strategic business plan for excellence (O2BX) to build organizational readiness in becoming a world class refinery by 2022, and re-aligned the safety targets with the new strategy – No Harm, No Leak, Goal Zero.
  • • Reviewed the five-year Occupational Health, Safety, Emergency, and Crisis Management Plan to align with both internal and external conditions, risks, and organizational strategic plans and targets.
  • • Reviewed, identified hazards, and assessed risks that may lead to serious accidents, and established controls and preventive measures. The effectiveness of the controls and preventive measures were monitored on an ongoing basis throughout the year. Furthermore, the Company conducted safety inspection and analyzes performance, and proposed corrective actions and preventive measures to avoid recurrence of safety incidents. The safety performance was also reviewed and inspected by management executives on a monthly basis Added.
  • • Reviewed Permit to Work System, with particular attention paid to permits for work with ignition sources near flammable sources, or hot work. All relevant checklists were also reviewed to ensure alignment with international best practices.
  • • Upgraded contractor safety management to align with international best practice, and the annual contractor safety performance review was completed. The Company continued to record the profiles and safety data of individual and corporate contractors through the electronic contractor safety passports, which also inform procurement practices and supplier management.
  • • Developed a security, safety, occupational health, and environmental performance evaluation system for contractors, and defined requirements for third party assessments covering management system and operational performance. Through this system, contractors were assessed and ranked into color coded levels of green, yellow, and red. The ranking results were then considered, alongside other criteria, in deciding if the Company would continue business with the contractors. Nonetheless, contractors who ranked under yellow or red levels – meaning their performance still did not meet Thaioil’s expectations – were given time to implement corrective actions.  
  • • Established a safety training center to develop the knowledge, capabilities, and skills of employees and contractors. The center is equipped to train in both theory and in demonstration and practice.
  • • Through the Competency Assurance System, the Company continued to assess and develop the knowledge and capabilities of employees and contractors whose roles relate to safety. This follows the work permit system and the roles and responsibilities as listed in the emergency and crisis management plan.
  • • Improved chemical management processes throughout the production, product testing, machine maintenance, and manufacturing processes, as well as handling of products and by-products within Thaioil Group, to align with international best practice standards.
  • • Organized All SAFE White Green MTA Project during the maintenance shutdown in 2021.
  • • Initiated the 30 60 90 Days with No Harms and No Leaks” activity to reiterate the importance of safety in the workplace to employees and contractors. The target of this initiative was to achieve zero medical treatment case resulting from work, and the Company successfully achieved this target.  
  • • Promoted awareness within the workplace hazards such as the line of fire, and communicated the 12 lifesaving rules to ensure strict compliance. We also continued encouraging the submission of potential incident reports (PIR), emphasizing the importance of identifying unsafe acts and unsafe conditions in preventing safety incidents.
  • • Reviewed health risk assessment during the annual maintenance turnaround by establishing proactive measures and controls aimed to prevent occupational illness. The effectiveness of the implemented controls and measures was then tracked and monitored by medical and occupational health experts. The Company invested in risk-based health and physical examinations for operators performing high risk activities. Performance was then analysed systematically to identify recommendations and corrective actions to avoid recurrence of incidents.
  • • Evaluated health performance indicators in accordance with internationally accepted standards, International Association of Oil and Gas Producers (IOGP). In 2020, the Company was scored 3.56 out of a total of 4.00 points. Based on these results, Thaioil developed an improvement plan to close the remaining gaps and meet IOGP criteria.
  • • Reviewed the emergency and crisis plan, including preparation of response plans in advance, to ensure alignment with international best practices. Meanwhile, the emergency control center was upgraded for a more modern design, and enhanced its readiness and efficiency.
  • • Continued to follow the COVID-19 surveillance plan. The plan includes three phases.In Phase 0, there are no infected cases and the Company continues preventive and surveillance measures. In Phase 1, suspected or infected cases are identified within Thaioil, but there are no impacts on business operations. In this case, the Company focuses on controlling and preventing the spread of the virus. In Phase 3, a high number of infected cases is identified in Thaioil and there are impacts on business operations. In this case, the focus is on implementing the recovery plan. The emergency control and business continuity center should be active.
  • • Improved the firewater supply systems and fire retention ponds to ensure readiness to respond to fire emergencies in any emergency situation and at any location – including in the production area as well as in the storage tanks. The Company also procured high performing water guns to strengthen our firefighting capability. 
  • • Conducted hazards and risks assessment with high severity, and reviewed mitigation controls and prevention measures. We also established plans and measures to maintain security and safety in various levels (Defence in depth), ensuring that these plans are inclusive of high severity risks – especially chemical spills from marine transport. The emergency drill is therefore extended to the level of crisis management in collaboration with external and local governmental agencies in order to prevent and reduce impacts on the business operations, while ensuring Thaioil Group can continue to manage high risk activities and control risks at acceptable levels at all times.
  • • The comprehensive incident management procedure in place, all incident shall perform the risk assessment and risk rating by utilizing Risk Assessment Matrix and select the investigation method base on risk rating to investigate and determine the root cause or causes of the work-related injuries, occupational illness, diseases, near miss and other incidents (included process safety event) so that corrective and preventive measures can be implemented to correct unsafe acts and conditions (hazards), as well as to prevent the incident from recurring.


Component of Occupational Health, Safety and Working Environment Committee

Thaioil committee of Occupational Safety, Health and Environment is responsible for the operation and management of all staff. People are safe in the workplace. With prescribed rules, regulations and procedures for the safe handling and with protective equipment as well as training provided to employees to have a better understanding of the work.  All performances are continuously monitored and there will be a review of the results.

The Safety Committee consists of the following members

1 Employer representative who is chairman of the board.

4 members of the Representative Commander.

1 Safety Officer as Director and Secretary.
5 Employee representatives (representing 50 percent of the board), handling the election of action.

Thaioil define the security policy as procedures and practice including the regulation of individuals (Blue Book, Section 11, which is a guide that was signed between the organization and the Department of Labor). This is a responsibility of all employees to follow procedures and guidelines set forth during work and to report to the commander for the event with the potential to cause an accident or harm or damage.



Promoting good health for employees

In order to promote good health among its employees, Thaioil puts an emphasis on being proactive by utilizing health risk assessment, which is part of the occupational health and safety standards. The process involves determining the consequences of being exposed to different substances, examining the risk factors, monitoring employees’ health conditions, and assessing their potential risks. Such an assessment should be conducted regularly so as to protect the company’s employees. In addition, monitoring of other contagious diseases, such as avian influenza, is vital. Information on how to protect oneself against such diseases should be provided to employees, especially those who have to work in an area where they may come into contact with certain diseases, for instance, employees who have to travel abroad.

Hearing Conservation Program

There has been no report on employees’ suffering from hearing loss resulting from work at the company.  Nonetheless, to preempt possible cases of noise-induced hearing loss (NIHL), the company has launched a campaign titled Hearing Conservation Program. This program comprises procedures to measure, analyze, and map the noise sources within the company (Noise Contour Map). Warning signs are posted in the areas with noises at the level below 80 dB (A), and employees and contractors are encouraged to wear hearing protection while working in those areas. Moreover, hearing tests are administered in order to detect any potential cases of hearing loss at an early stage, and this is believed to help reduce the risk of NIHL development in the future.

Office Ergonomic

Since the company’s staff members have to work in front of computers continuously for an extended period of time, their health conditions may be affected, which, in turn, may impact upon their performance. Risk assessment has been conducted with the help from health professionals, and their feedbacks regarding office equipment and break times have been incorporated into the company’s plan to create a safe work environment for its staff. With employees’ good physical and mental health, Thaioil can operate in an efficient manner. Because of this health assessment program, for 53 years, there have been no reported incidents of employees suffering from illnesses that result from the operation.

Fit for Work

Group recognizes the importance of preparing the body fitness for the workers so they are ready for operation (Fit for Work). Workers operated with risk, such as working on high places. Health care of employees include being given medical treatment, but without the need to look after diseases such as hypertension, diabetes and heart disease, as well as employees who are obese or with high Body Mass Index (BMI) exceeding the standard from which their care can reduce the risk of accidents due to health problems.

Process safety

Process safety is very important for the operations. Therefore, all production functions of Thaioil Group are operated under effective management system and international standards in safety, occupational and environment. Thaioil Group has zero loss of primary containment (LOPC) Tier 1 target and appointed Safety Committee where at least half of the members must be employees’ representatives. The Committee is accountable for corporate safety management, monitoring and verifying performance against the Group’s standards and providing safety knowledge to all employees in order to enhance safety performance at the corporate level and achieve identified goals.

Transportation safety
