Occupational Health and Safety

Occupational Health and Safety Management at Türk Telekom

Occupational Health and Safety

We position protecting the health and safety of our employees at the highest level among our core priorities. We consider employee well-being as an integral part of corporate sustainability. In this regard, we implement and certify the ISO 45001 Occupational Health and Safety Management System across all our field and operational activities. In line with the OHS policy defined in our Integrated Management System Policy, we address occupational health and safety together with quality, environment and customer satisfaction, and adopt a continuous development and improvement approach across all our processes. Through this integrated structure, we aim to ensure the systematic management of risks and enhance corporate resilience.

In our OHS practices, we not only ensure compliance with legal and regulatory obligations but also encourage our business partners to adopt and implement these standards. We prioritise the dissemination of an OHS culture across our entire value chain. We systematically evaluate feedback from our employees and carry out corrective actions in line with the findings identified during occupational safety inspections. By conducting regular risk assessments across our areas of operation, we aim to minimise issues that involve high risk and require urgent action. Our Board of Directors regularly oversees the findings obtained. We contribute to our continuous improvement approach not only through risk assessments but also through training activities and preventive practices. Through these monitoring and evaluation activities, we aim to protect the health of our employees and stakeholders and ensure Occupational Health and Safety the sustainability of a safe working environment.

We adopt a risk management approach based on a preventive perspective. We implement our OHS management system through a holistic approach that covers all our operations and business partners. Within the scope of our OHS Risk Assessment Procedure, we carry out location- and activity-based hazard identification and risk assessment studies and implement preventive and corrective actions for high-risk areas. Through these efforts, we aim to ensure that potential risks are brought under control before they materialise. We actively encourage employee participation through employee reporting systems, corrective action mechanisms, OHS committees and representatives. We consider employees’ direct contribution to the process to be critical for the effectiveness of OHS management. In cases of serious and imminent danger, we grant our employees the right to refrain from work in accordance with Law No. 6331. By using the data obtained through near-miss notifications and accident root cause analyses, we carry out activities aimed at preventing the recurrence of similar incidents. In 2025, approximately 15,878 inspections were conducted within the scope of OHS across our regional directorates. These inspections constitute one of the most important tools supporting our continuous improvement approach in the field. Our OHS Committees are established in accordance with legal regulations and company procedures. They convene regularly with the active participation of employee representatives and ensure that the decisions taken are reflected in field practices. Through these committees, a participatory and transparent governance structure is established. We monitor our OHS performance through key performance indicators such as the accident frequency rate, the lost-time injury rate and the number of inspections per employee. These indicators enable the regular monitoring of our OHS performance and provide input for management decision-making.

Our OHS practices are carried out by the Health Services and OHS Directorate operating at the headquarters, together with OHS professionals affiliated with the regional directorates (occupational safety specialists, workplace physicians and other health personnel). These teams ensure the effective functioning of the system through field inspections, incident investigations and improvement recommendations. In addition, we regularly monitor legislative updates and implement them through Legal Compliance Assessment Tables.

OHS committees are established at each of our workplaces and convene at intervals appropriate to the hazard classification. Employee representatives serving on these committees are determined either by authorised trade union representatives or through election among employees. Our employees can convey their views, suggestions and complaints to the committees through their representatives and can also report near-misses and hazardous situations through online and manual systems. These mechanisms support the active participation of employees in OHS processes. In addition, our employees directly contribute to the process by taking part in the relevant teams involved in risk assessment activities conducted at their workplaces.

In order to further advance our OHS processes, we aim to implement VR and AI-supported applications. Through these technologies, we seek to enhance awareness and the effectiveness of learning, particularly in high-risk activities.

As part of Occupational Health and Safety Week, we organised an awareness event to promote the OHS culture among our employees. As part of the event, our managers from the Ankara Headquarters and Regional Directorates, OHS coordinators, solution partners and expert academics were brought together. E-seminars and informative articles on topics such as Office Ergonomics, Stress Management in Working Life, Oral and Dental Health, Post-Holiday Syndrome and HIV/AIDS were shared with all employees. Through these events, we aim to increase the visibility of OHS on the corporate agenda.

Occupational Health and Other Health Services Practices

To protect the health of our employees, we regularly conduct pre-employment, periodic and return-to-work medical examinations through our workplace physicians. Through these processes, we ensure the continuity of employee health. In addition, through the outpatient clinic services provided at our Headquarters, we enable our employees to access healthcare services across different medical specialisations.

We also provide our employees and their families with access to healthcare services under favourable conditions through discountagreements with external healthcare providers. In addition, through alternative Private Health Insurance models offered via the Türk Telekom Health and Social Welfare Foundation, we provide our employees with comprehensive health coverage. Through these practices, we aim to support the physical and mental well-being of our employees. Although no occupational diseases have been recorded to date, we take preventive measures and conduct training activities to raise awareness among our employees on the prevention of occupational diseases. In this context, we adopt a preventive health approach.

Within the scope of the Company’s Human Resources Policy, we implement the necessary risk assessment processes to protect employees’ rights, ensure fair working conditions, prevent discrimination and maintain a safe working environment. In this context, we monitor activitities within the company in terms of social risks, and we undertake efforts to ensure compliance with legislation, industry practices and corporate standards.

OHS Management of Suppliers, Subcontractors and Contractors

We do not limit our OHS policies to our own employees; we also require our suppliers, subcontractors and contractors to apply the same standards. We aim to establish a shared safety culture across our entire business ecosystem. In this context:

• We require subcontractor and contractor employees to complete OHS training and verify their OHS training certificates upon entry to the worksite. Supplier employees without valid training certificates are not permitted to enter the worksite.

• We include occupational safety and environmental specifications in the contracts signed with our suppliers, subcontractors and contractors, and we do not work with companies that fail to comply with the established safety standards.

• As of 2025, within the scope of the “Supplier & Partner Portal” project that has been put into operation, we monitor the health and safety performance of our suppliers through surveys, internal stakeholder assessments and audit processes. Through this system, we aim to make supplier OHS performance more transparent and traceable.

2025 – Occupational Health and Safety e-Training: The training was assigned to 17,288 employees. 14,225 employees completed the training, resulting in a completion rate of 82%. In 2025, the Occupational Health and Safety e-training was not opened to all employees; instead, within the scope of the RPA project, assignments were made to employees who are required by legislation to receive the training, based on their hazard classification.

2025 – Environmental e-Training: The training was assigned to 17,288 employees. 14,852 employees completed the training, resulting in a completion rate of 86 %. In our Company, the Accident Frequency Rate (Ratio) Target is monitored on a regional basis using scales developed each year by evaluating the previous year’s data, within the scope of occupational health and safety. Similarly, there is a target for the accident frequency rate (ratio) that is adopted and monitored by the relevant Directorate of the General Directorate, in line with the scale created for the entire Company. As Türk Telekom, in line with our legal obligations and with the aim of increasing OHS awareness, we conduct regular training programmes to ensure that our employees operate in a healthy and safe working environment. As an important part of our peopleoriented approach, these trainings aim to strengthen our employees’ competencies in recognising risks, implementing preventive measures and adopting a safe working culture. In this way, we adopt a proactive approach to preventing occupational accidents and diseases. Within the scope of the OHS trainings organised:

• We address the root causes of occupational accidents and the prevention principles aimed at avoiding such incidents,

• We share practices aimed at identifying and eliminating hazardous conditions and unsafe behaviours,

• We provide information on occupational diseases, their risk factors and the preventive measures that can be taken against these risks,

• We provide information to office employees on physical, chemical and ergonomic risk factors.

• Through the OHS Training for Employer Representatives, which is specifically designed for employer representatives, we aim to enable managers to fulfil their occupational health and safety responsibilities more effectively.

Through our Occupational Health and Safety training programmes, we aim to instil safe behavioural habits, support employees in recognising risks in the field at an early stage, increase awareness of long-term health impacts and contribute to creating healthier and more ergonomic working environments.

Through the OHS Training for Employer Representatives, which is prepared with dedicated content for managers who play a critical role in OHS management, we aim to enable employer representatives and managers to fulfil their responsibilities arising from legislation more effectively and to manage OHS practices in the field more robustly. Through these trainings, we aim to strengthen managerial responsibilities and further embed the OHS culture across the organisation.
