Summary of the Grievance and Mediation Policy 10.4 Occupational Health and Safety 10.4.1 Work Safety Management The United Laboratories adheres to the management philosophy of “safety first, prevention-oriented” and regards work safety as a key operational priority. The Group continuously enhances its occupational health and safety (OHS) management framework and system, and requires all units to strictly comply with applicable laws, regulations and internal policies. Through mechanisms such as risk identification, training and education, emergency management and continuous improvement, the Group seeks to reduce accident risks and safeguard employees’ health and operational safety. The Group has established an occupational health and safety management system and obtained relevant third-party certifications. Among them, Inner Mongolia Company has been certified to the ISO 45001:2018 Occupational Health and Safety Management System and has also passed the Level II Work Safety Standardisation assessment, providing a methodological foundation and management framework for system implementation and on-site control. Under the guidance of this management system, all departments are required to comply strictly with legal and regulatory requirements as well as internal policies, conduct regular safety risk assessments, identify potential risks across different work areas and job functions, and formulate corresponding risk control measures. The Group promotes the effective implementation of management requirements across all levels and functions through structured governance. Taking Inner Mongolia Company as an example, safety risk and hazard identification and inspection are coordinated and supervised by the Safety Department under the authorisation of the Safety Committee. Functional departments carry out specialised inspections based on their respective responsibilities and maintain inspection records, while relevant departments/workshops continuously track rectification actions and ensure closed-loop management. To ensure the effective implementation of occupational health and safety measures, the Group has established a closed-loop management mechanism of “Plan – Do – Check – Act (PDCA).” The Safety Production Committee provides overall supervision, while the safety and environmental protection departments organise all units to conduct on-site inspections, specialised checks and management audits on an annual and quarterly basis. These activities cover key areas such as high-risk operations, equipment and facility inspections, use of personal protective equipment, hazardous chemicals management and contractor operations. For issues identified during inspections, responsible departments and personnel, rectification deadlines and acceptance requirements are clearly defined, and follow-up actions are tracked to ensure effectiveness. At the same time, trend analysis is conducted based on indicators such as accident and near-miss reporting, occupational hazard monitoring results, employee health examinations and training completion. Findings are regularly reported to management and incorporated into management reviews to update control measures and drive continuous improvement. , 93 The United Laboratories International Holdings Limited 2025 Environmental, Social and Governance Report
