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.

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.

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

Thaioil Group’s transportation is operated under PTT Group Road Safety Management System which comprises safety management, driver management, a safety checklist report prior product delivery, and monitoring system to ensure punctuality transportation time and regulations in order to reduce safety risk.
