Occupational Health and Safety

Occupational Health and Safety Management at Türk Telekom

At Türk Telekom, we implement and certify the ISO 45001 Occupational Health and Safety Management System across all our sites to ensure the highest standards of employee health and safety. As part of our Integrated Management System Policy, we address occupational health and safety alongside quality, environmental, and customer satisfaction management systems, ensuring continuous improvement and development across all processes.

We are committed to managing occupational health and safety in full compliance with applicable national and international legislation and regulatory requirements. We develop systems and processes that encourage employee participation and undertake initiatives to prevent workplace accidents, health impairments, and occupational diseases. We prioritise emergency scenarios in line with our risk-oriented approach, aiming to eliminate hazards at their source and minimise existing risks.

At Türk Telekom, we implement our occupational health and safety (OHS) management system across all employees and operations. As part of our OHS Risk Assessment Procedure, we carry out hazard identification and risk assessments based on location and activity and we implement preventive measures in high-risk areas.

We encourage employee participation through our reporting system, corrective action mechanisms, OHS committees, and employee representatives. In cases of serious and imminent danger, we grant employees the right to refuse work in accordance with Law No. 6331. We identify potential hazards in advance through near-miss reports, field inspections, and root cause analyses of incidents, and take the necessary preventive actions. In 2024, approximately 13,000 occupational health and safety inspections were conducted across our regional directorates.

Our OHS Committees are established in line with legal regulations and company procedures. They convene regularly with active participation from employee representatives and ensure that decisions are implemented in the field. We monitor our OHS performance through key performance indicators such as the accident frequency rate and the number of inspections per employee.

Our OHS practices are carried out by the Health Services and OHS Department at headquarters, together with OHS professionals—specialists, doctors, and health personnel—based in our regional offices. These teams actively support the system through field inspections, incident investigations, and improvement proposals. We also monitor legislative updates regularly through Legal Compliance Assessment Tables and implement changes accordingly.

In 2024, we achieved improvements in workplace accident indicators compared to the previous year:

• The total number of accidents decreased from 291 to 277 (a 4.8% reduction).

• The number of lost-time injuries dropped from 142 to 127 (a 10.6% reduction).

• The number of lost workdays declined from 1,994 to 1,783.

• The accident frequency rate fell from 5.7 to 5.5.

• The lost-time injury rate decreased from 2.8 to 2.5.

Employee Health and Medical Services

At Türk Telekom, we carry out pre-employment, periodic, and return-to-work medical examinations through our occupational physicians to protect the health of our employees. In addition, our in-house outpatient clinic at the Head Office allows employees to receive healthcare services from physicians in various specialties.

As a company, we offer our employees and their families access to discounted healthcare services through agreements with external medical institutions. We also support all employees in accessing private healthcare services through the Türk Telekom Health and Social Welfare Foundation. While no occupational illnesses have been recorded, we take preventive measures and provide training sessions to raise employee awareness on this issue.

OHS Management for Suppliers

At Türk Telekom, our occupational health and safety policies extend beyond our own workforce; we require our suppliers and subcontractors to apply the same OHS standards.

• We require supplier employees to complete OHS training and check for valid OHS certificates before site access. Employees without training documentation are not permitted to enter the site.

• We include occupational safety and environmental specifications in supplier contracts and discontinue engagement with firms that fail to meet defined safety standards.

• We plan to monitor health and safety performance of suppliers via surveys, internal stakeholder assessments, and audits as part of our upcoming “Supplier & Partner Portal” which will come into effect in 2025.
