Workplace protectionIncluding the activities of the Kubanenergo branch in December 2025.

The Company’s main goal in workplace protection is to ensure workplace safety and protect the health of employees by preventing work-related accidents and occupational diseases, as well as to improve the level of safety culture.

The establishment and operation of the occupational health and safety management system (hereinafter referred to as the OHSMS) at PJSC Rosseti South takes into account state regulatory requirements for occupational health and safety, the commitments made on occupational health and safety, as well as national standards.

In accordance with the requirements of the Labour Code of the Russian Federation, with the aim of ensuring continuous improvement of occupational safety activities and the preservation of the life and health of employees, the Regulations on the occupational safety management system at PJSC Rosseti South (hereinafter referred to as the Regulations) were approved and put into effect.

Risk assessment

Risk assessment is an important tool to identify hazards and risks in a timely and systematic manner and to take preventive measures.

An appropriate procedure is established for the identification (detection) of hazards and assessment of occupational risk levels at workplaces.

The procedure for identifying (detecting) hazards and assessing occupational risk levels includes the following measures:

• Identification of workplace hazards in structural units with control measures in place
• Assessment of the levels of occupational risks from each identified hazard
• Assessment of the acceptability (admissibility) of the assessed levels of occupational risks
• Analysis and assessment of the adequacy of existing measures to manage and control occupational risk levels

The results of hazard identification and assessment of risk levels at workplaces are communicated to employees in the following ways:

• By including in workplace health and safety briefings
• By posting summary data on the risk assessment results in publicly accessible places (information stands, occupational safety and health desks, etc.)

Information on detected (identified) hazards and occupational risk levels is used at all levels of occupational health and safety management.

Training

A high professional level of training for the Company’s employees is one of the requirements for the OHSMS to operate effectively.

The professional competence requirements for employees to perform their work are established by regulatory legal acts, professional standards, local regulations and other internal documents of the Company.

Knowledge and practical skills acquired by workers are analysed with due account of the results of on-the-job training, shadowing, emergency and fire drills, as well as the results of periodic observations (various types of control) of how the employee performs the functions and tasks assigned to them.

In order to make occupational safety training of employees more effective, structural subdivisions ensure the availability of occupational safety rules and instructions, as well as other materials necessary for safe performance of work.

Investigation and recording of accidents

Work-related accidents, occupational diseases, micro-injuries (micro-damage) at the Company’s workplaces are be investigated and recorded.

The purpose of investigating the causes of accidents, occupational diseases and other injuries is to prevent the deterioration of employee health and safety and to identify deficiencies in how the OHSMS functions.

Measures to investigate and record accidents and occupational diseases include:

• Organising the reporting of accidents and occupational diseases to the competent authorities and organisations
• Organising and ensuring a proper and timely investigation of an accident and ill health, drawing up investigation materials in accordance with legal requirements

Assessment of working conditions

A special assessment of working conditions is a unified set of consecutive measures aimed at identifying harmful and/or hazardous factors in the working environment and work processes and assessing their impact on employees, taking into account any deviations from the standards (hygiene standards) for working conditions established by the federal executive authority authorised by the Government of the Russian Federation and the use of individual and collective protective equipment for employees.

Employees who perform their duties at workplaces that do not meet state regulatory requirements for occupational health and safety are paid compensation for work in hazardous working conditions, are granted additional paid leave, increased wages, and are provided with milk or other equivalent products (monetary compensation).

For protection against harmful and (or) hazardous factors of the production environment and (or) pollution, as well as at work performed in special temperature conditions, employees are provided free of charge with personal protective equipment and washing agents that received confirmation of conformity in accordance with the procedure established by the legislation of the Russian Federation on technical regulation. The Company’s personnel are provided with personal protective equipment to the full extent.

In order to monitor, control and evaluate the OHSMS performance, the health of employees is monitored, including preliminary and periodic medical check-ups (examinations) and psychiatric examinations.

In accordance with legal requirements, the Company organises medical check-ups: once every two years for employees whose workplaces are found to have harmful and/or hazardous production factors and for vehicle drivers, and every year for persons authorised to work at heights.

In 2025, occupational health and safety measures required by law were fully completed at the Company.
