Shihlin Electric is committed to creating a comfortable, safe, and healthy working environment, continually reducing the rate of occupational accidents. We have established an "Occupational Safety and Health Policy" as the highest guiding principle for safety and health management, actively improving workplaces, manufacturing equipment, and work procedures to protect the rights and safety of workers and stakeholders. Occupational safety and health management at each production and operation site—covering worker participation, consultation, communication, and the prevention and mitigation of business-related health and safety impacts—is carried out in accordance with the chapters and clauses of the occupational safety and health management system. Annual third-party audits ensure continued certification validity. The system encompasses all employees and all non-employee workers within our facilities. To comply with domestic EHS regulations and align with international management systems, the company has invested in safety management resources. Since 2020, we have been certified under ISO 45001:2018 and CNS 45001:2018. We implement a "safety management cycle" composed of legal compliance, system development, policy and target setting, solution planning, incentive and disciplinary measures, and performance review, all aimed at achieving zero workplace accidents.

Occupational Safety and Health Committee

To enhance workplace safety and provide a secure working environment for both employees and contractors, Shihlin Electric has established an Occupational Safety and Health Committee in accordance with legal requirements, aiming to contribute to sustainable development. The committee is chaired by the factory director, who is the highest-ranking manager of the facility, with a safety and health department member serving as the executive secretary. More than one-third of the committee members are employee representatives, ensuring labor participation in reviewing and promoting safety and health matters. Regular committee meetings are held every three months, with additional meetings convened as necessary. Agenda items include safety and health incident reports, stakeholder concerns, assessment results, performance targets and improvements, regulatory updates, employee health protection, and health promotion efforts. The committee also reviews the effectiveness of the occupational safety and health management system, ensuring continuous improvement in workplace safety and health performance.

Hazard Identification, Risk Assessment, and Incident Investigation

In alignment with the occupational safety and health management system, Shihlin Electric has established a Hazard Identification and Risk Assessment Process. The scope includes all routine and non-routine activities carried out by in-plant workers. Annual identification and updates of occupational safety risks and opportunities are conducted. All designated personnel receive annual training on risk assessment methodologies and hazard control awareness. For identified high-risk factors, the company analyzes their potential impact, plans control measures, and integrates them into OSH goals and management programs. These control measures are periodically reviewed through management review meetings to ensure their effectiveness and applicability. The company has established internal procedures such as the “Incident Handling and Investigation Management Procedure”, “Emergency Response Procedure” and “Nonconformance Corrective and Preventive Measures Procedure” to facilitate prompt communication, resolution, and prevention of future incidents. These procedures apply to all workers and stakeholders within the company and cover fire, chemical hazards, injuries, near misses, and other accidents. Workers who report risks or hazards are protected from retaliation. Furthermore, in compliance with the Occupational Safety and Health Act, workers are allowed to evacuate to a safe location via a secure route in the event of immediate danger (e.g., explosion, fire, earthquake) without fear of punishment.

Workplace Environment Monitoring

To mitigate potential health hazards in the workplace, Shihlin Electric regularly conducts workplace environment monitoring, including planning, sampling, analysis, instrument measurement, and exposure assessment. 1.Monitoring Frequency: Conducted semi-annually (January and July). 2.Hazard Assessment: Conducted by the factory manager, OSH personnel, manufacturing supervisors, labor representatives, and certified technicians, evaluating physical and chemical properties to draft monitoring plans. 3.Health Management: Special hazardous operations require the establishment of health management data and implementation of specific health examinations with result-based risk classification. 4.Monitoring Results: Before testing, monitoring details are pre-registered on the Taiwan OSHA website. On-site measurements are conducted by certified professionals from accredited institutions, and results are submitted and made public on the OSHA platform.
