Occupational Safety and Health

Occupational health and safety management system

Wistron’s plants leverage ISO 45001 OHS Management System to maintain effective operations. Through education, training, promotion, and drills, the company ensures that all stakeholders have a clear understanding of their safety and health obligations and rights. This proactive approach aims to reduce and eliminate risks and impacts related to occupational safety and health.
 

Labor Safety Committee

All Wistron plants have established a Labor Safety Committee to facilitate communication, provide consultation, and respond to complaints. The members of the Committee include managers responsible for decision-making as well as labor representatives. They serve to provide communication channels for employee participation and consultation in occupational safety management systems. Employees can offer their thoughts or suggestions on occupational safety and health to department representatives who will share employee feedback during annual meetings, allowing our employees to communicate with senior executives through the Committee.
 

Occupational Safety and Health Measures

Internal Audit

Education and Training on Occupational Safety and Health

To ensure employees fully understand Wistron’s occupational safety and health regulations and management system, and are equipped to respond to hazards and accidents, we conduct annual audits involving on-site inspections and verification activities. Additionally, all new employees are required to undergo general introductory education courses, such as Responsible Business Alliance (RBA) training. For employees in specific job positions where unique hazards may occur, Wistron will continue to provide tailored specialized training. This includes emergency rescue drills at the Hsinchu plant and energy response drills at the Zhongshan plant, which focus on strengthening employee safety awareness and validating the safety of the working environment. In 2025, a total of 271,712 individuals completed training, accumulating 276,382 training hours. Each plant conducts regular emergency response training to ensure familiarity with processes. This ensures the effectiveness of organizational disaster recovery mechanisms and reduces false alarms. In 2025, there were 54 reported cases. For historical data, please refer to the section on internal near-miss incidents.

Hazardous Substance Management

Trained and qualified professionals are tasked with overseeing the management of hazardous chemicals used in manufacturing processes. Comprehensive controls are in place for the procurement, handling, storage, and use of hazardous chemicals. In 2025, environmental initiatives at manufacturing sites focused primarily on reducing environmental impacts through planned process improvements. In addition, annual occupational safety and health training programs provide operational training, emergency response procedures, and knowledge development. Safety Data Sheets (SDSs) are prominently displayed for easy reference, enabling personnel to respond effectively in the event of an emergency.
 

Workplace Hazard Identification and Risk Assessment

Trained and qualified personnel are responsible for conducting task-related hazard identification and applying quantified risk factors as the basis for risk assessment. Following review by the occupational safety and health management unit, risk levels are established, and operational controls and improvement objectives for hazard risks are defined. These are tracked regularly within the occupational safety and health management system to ensure potential occupational hazards are consistently eliminated from the workplace.

In the event of an immediate and dangerous emergency during any operation, employees are authorized to assess the situation based on the severity of the danger present and then determine whether to cease operations or take necessary protective measures before evacuating without adverse consequences. In 2025, Wistron continued to manage this occupational safety risk indicator (facility incident rate ≤1.14‰) as a medium- to long-term performance target. Through planned training programs and periodic inspection mechanisms, the Company effectively monitored and tracked site indicators on a monthly basis to reduce the likelihood of risk occurrence, and no related risks were identified in 2025.

Most medium-to-high-risk items involve injuries caused by improper actions during routine operations involving mechanical equipment. To mitigate these risks, employees receive additional training to ensure the proper use of personal protective equipment and to review work procedures, thereby reducing the likelihood of incidents.

 

Voluntary Reporting of Near Miss Incidents

Wistron has SOPs in place for near-miss incidents, such as fires, power outages, or earthquakes. They are reported to the responsible units in accordance with the Incident Response and Investigation Management Procedures to verify whether an incident has occurred, conduct investigations, track events, and promote safety and health. Where no significant property damage or casualties have occurred, the event is recorded in the near-miss incident log, submitted for approval, and retained for reference. The Company analyzes the causes, formulates corrective and preventive measures, evaluates the effectiveness of these measures, and continues to monitor improvement efforts.

To minimize delays in communication, Wistron continues to strengthen its digital communication platforms through AI applications, including Columbus, Wistron’s internal knowledge platform. By integrating a smart assistant module, the platform provides employees with Q&A services. Additionally, internal communication procedures are in place to facilitate quick reporting of any emergencies or near-miss incidents.

In 2025, there were a total of 54 near-miss incidents. The majority of near-miss incidents were caused by equipment and facility malfunctions or negligence, such as false fire alarms. Prompt action and subsequent measures were taken to verify the functionality of related equipment and enhance inspection procedures, respectively. Specific maintenance precautions are also included to prevent similar incidents in the future.
 

Accident Investigation

Data on Occupational Hazards & Injuries

Wistron identifies occupational safety and health issues with potential risks by analyzing data on occupational hazards and injuries, which guides the formulation of specific action plans to improve workplace safety and reduce work-related injuries. Work-related injury statistics for Wistron employees and non-employee workers in 2025 are shown in the table below. Each plant reports detailed information on work injuries by month, as well as monitoring and tracking by designated personnel to ensure they stay informed about work injury management.

The tables below are compiled based on legal reporting requirements, with a focus on recording injuries. The definition of severe occupational injuries follows government regulations. We have not received any reports on occupational diseases. In terms of managing non-employee workers, all Wistron plants comply with local regulations in managing on-site personnel and subcontractors. Through vendor selection and contractor management, Wistron assesses and standardizes operational standards for suppliers to achieve our expected results from OHS management systems. In 2025, no significant violations (defined as violations with ≥NT$1M fines) occurred in the management of subcontractors.

In 2025, the lost workday rate among employees in Taiwan increased compared with the previous year, primarily because employees were unfamiliar with traffic routes and commuting patterns following the relocation of the Hsinchu/Hukou sites, resulting in a higher number of commuting-related traffic accidents. Administrative units continued to strengthen communication on traffic safety through bulletin boards and introduced safety awareness sessions and traffic-reduction measures (such as shuttle bus services). In Asia (excluding Taiwan), the lost workday rate decreased compared with the previous year. Most occupational injuries were minor injuries, and the Company responded by reviewing standard operating procedures and strengthening foundational training. In Europe and the United States, the lost workday rate increased compared with the previous year, primarily due to mechanical injuries caused by improper handling. In response, Wistron strengthened employee training, reviewed standard operating procedures, and ensured that employees properly wore protective equipment to prevent injuries.
 

Employee Absence Rate

Note 1 : Absence Rate: Number of absent days/Number of days to work*100. The number of days to work: refers to the number of working days.The number of working days is the sum of the total annual working days of each plant around the world.
Note 2: Absent days include work injuries and sick leave (Sick leave excludes leave taken due to the pandemic).
Note 3: The target value of absenteeism rate in 2025 was set at 0.85 (set to not exceed the average value of the previous three years).
