Occupational Health and Safety in the Workplace

Occupational health and safety is an essential aspect of sustainability in the Company's business operations. Improper safety management may result in the disruption of the production process, loss of life, property and the impact on the image and reputation of the Company as well as the Company's stakeholders. As a result, to manage risks that may affect stakeholders and the organization, particularly employees, contractors/trade partners, and surrounding communities, the Company has established an Occupational Health & Safety Policy that requires all employees and contractors to have a duty of care for the safety of themselves and their colleagues, including compliance with the law. The Company has adopted the ISO 45001:2018 Occupational Health and Safety Management System for the management (GRI 403-1) by setting objectives, goals, and management plans, regularly reviewing and tracking operating results. The Company sets up the Occupational Safety, Health and Working Environment Committee (OSH&E Committee) to perform supervisory duties and continually improve safety, occupational health, and work environment implementations, as well as setting occupational health and safety goals of the Company

In 2025, the Company had a total of 18 factories certified under the ISO 45001 Occupational Health and Safety Management System by external certification bodies, as follows:
Sheet Rubber Factory:
• Sri Trang Agro-Industry Public Company Limited, Trang Branch
Block Rubber Factories:

• Num Hwa Rubber Co., Ltd.
Concentrated Latex Factories:
• Sri Trang Agro-Industry Public Company Limited: Hat Yai, Trang, and Kanchanadit Branches

In 2025, all branches of the Block Rubber product group were certified under the ISO 45001 Occupational Health and Safety Management System by external certification bodies. For 2026, the Company plans to expand certification as follows: the Concentrated Latex group aims to include the Surat Thani branch, targeting full certification of all branches by 2031, and the Sheet Rubber product group plans to include the Chiang Rai branch, targeting full certification of all branches by 2028. Additionally, the Company organizes regular occupational health and safety meetings for the natural rubber group and reports performance to the Audit Committee on a quarterly basis. The Company has received the Outstanding Model Enterprise Award for Safety, Occupational Health, and Work Environment from the Department of Labour Protection and Welfare and has been continuously certified as a “Safe, Healthy, and Happy Workplace” by the Department of Health across multiple factory branches. These recognitions reflect the Company’s effective management of occupational health and safety. Key initiatives conducted in 2025 included the following:

Hazard Identification Process, Risk Assessment, and Incident Investigations (GRI 403-2)

To proactively manage and prevent accidents and reduce risks that may cause serious accidents, including occupational diseases. The Company has carried out work-related hazard identification and assessment of occupational health and safety risks by covering both activities performed by employees and contractors. In identifying hazards, duties, nature of work, location, activities, and potential hazards are taken into account, including social factors, work design, past incidents, and changing work processes in order to prepare a risk control and established control measures to eliminate hazards and reduce risks at work following the Hierarchy of Controls. The Company also sets up a risk assessment and process review at least once a year in order to continually improve and develop the occupational health and safety management system.

The Company has also established procedures for dealing with physical or property incidents, including occupational diseases. Employees have to analyze hazards or abnormal events in the work process, investigate the root cause of the incident, and then define measures to effectively correct and prevent a recurrence, including continually improving safety management. Moreover, the Company organizes a monthly meeting of the safety working group of every branch factory to promote the creation of a safety culture in the Company group. The Company also communicates accidents through the RCS Application, an accident notification system within the Company group to be informed when an accident occurs at any branch in order to prepare and prevent the recurrence of accidents.

In 2025, the assessment of operational safety risks identified high-consequence work-related hazards, including chemical-related accidents, machinery-related incidents such as those involving conveyor belts and rollers, and fire-related accidents. The task force implemented control and risk mitigation measures, including the installation of machinery guards, Safety Switch systems, development of safety manuals, and the application of Behavior-Based Safety (BBS) activities to promote safe working behaviors.

From the Company’s incident reporting and analyses, it was found that 40.66 percent of bodily accidents were caused by unsafe actions, 17.58 percent were caused by unsafe working conditions, and 41.76 percent were caused by unsafe actions and unsafe working conditions, as per the following details.

The top 5

  5. Incorrect factory layout or confined workspace;
In addition to the issue of bodily accidents, fire is an incident that results in the loss of very high-value property. To raise safety and proactive prevention awareness regarding fire suppression in the factory, the Safety Center team has assessed the accident and fire preventive measures according to the manual of the Institute for the Promotion of Occupational Safety, Health, and Work Environment (public organization), which consists of four topics:
  • Fire prevention and suppression
  • Electrical radiator/boiler system that uses liquid as a heat conductor
  • Chemical safety
  • General safety related to fire
The assessment results indicated that the Company’s Block Rubber, Sheet Rubber, and Concentrated Latex factories achieved scores exceeding 90% of the evaluation criteria. The assessment team also developed a follow-up plan and provided recommendations for improvement. In addition, the Company’s Safety Center 2025 team conducted inspections across a total of 27 factories within the Sri Trang Group. The Company has been monitoring the implementation of the recommendations and corrective actions through the Occupational Health and Safety Department.

Health and Occupational Health Services (GRI 403-3)

Apart from the importance of safety at work, the Company is aware of the care and prevention of health hazards of employees and those who work in the Company’s area, which may have an environment that may cause health hazards. The Company has adopted a proactive occupational health process. It provides occupational medicine doctors to assess the health risks of employees and those who work by covering operations in all areas that lead to plan appropriate control and risk reduction measures. It also entails regular monitoring and measuring of various working conditions, such as light, sound, heat, dust, and chemicals. In the event that the measurement results do not meet the specified safety standards, the Company will take corrective and preventive measures to design and improve the work area to have a better environment and systematically monitor to make such measurements pass the specified standards.

The Company provides a hospital room for health services to employees and contractors working in the area. It also provides health checks for new employees before starting their work or a change in positions, an annual health check-up of employees, and health check-up according to risk factors by occupational medicine doctors, including providing safety officers acting for supervision, suggestions, and consultation to employees and contractors on issues related to occupational health and safety.

Participation in Consulting and Communicating Information Related to Occupational Health and Safety (GRI 403-4)

The Company has appointed the Occupational Safety, Health and Working Environment Committee, a working group established by law in the workplace. The responsibilities of this committee are to promote employees’ participation in occupational health and safety operations and risk management. It is the participation of representatives from the management team and employees collaborating to establish a safe and good working environment, including a continuous and consistent improvement and development of the occupational health and safety management system. The employee representative working group consists of employees at the operational level. The employees’ representatives consist of operational staff elected from different lines to communicate with employees from all lines and levels. The working group is required to hold a meeting at least once a month to exchange information, provide feedback, and follow up on the progress of safety operations to improve operations continually and consistently.

The Company also organizes safety promotion activities and communicates safety information to employees at all levels. Examples include reporting safety-related behaviors through the BBS Observation Card via the RCS Application to report unsafe or safe behaviors observed, monthly safety quizzes, and participation in activities such as 5S, KAIZEN, QCC, KYT, and Safety Talks. In 2025, the Company conducted its 6th consecutive annual “Safety and Environmental Conservation Culture” program in an online format on 27 March 2025, simultaneously across all branch factories. Additionally, on-site activities were held at each branch from 1 April to 15 May 2025 to raise awareness and reinforce safe working practices among all employees. These initiatives reflect the Company’s ongoing commitment to fostering a strong safety culture throughout the organization.
