Home  /  COMPANY  /  TVO as an employer  /  Principles for management of occupational health and safety


The occupational health and safety activities are steered by the Occupational Health and Safety System certified to the OHSAS 18001 standard. It also applies to activities on the OL3 construction site within TVO's area of responsibility.

The occupational health and safety policy is written in the Group-level policy under the sub-area of corporate social responsibility. The premise applied to the occupational health and safety policy is the zero accidents philosophy, maintenance of a good working atmosphere and working conditions, and zero tolerance of harassment or bullying in the workplace.

TVO aims at guaranteeing a safe working environment for all employees, including the employees of contractors and service providers, and ensuring that standardised procedures and practices are followed in the Group’s operating area. Everybody working in the Olkiluoto area is required to complete the occupational safety card training. TVO employees attend this training at the start of their employment. According to the zero accidents objective, all accidents can be avoided through good planning of work, proactive risk identification and high standard of implementation of work.

Occupational safety cooperation across organisational boundaries

Occupational health and safety activities are coordinated by the experts in health and safety in the Fire Safety and Environmental Safety Team of the Competence Centre for Corporate Security. They include the OHS Development Manager, three OHS Managers and an OHS Supervisor.  The personnel (workers and salaried employees) have elected occupational safety representatives and deputy representatives from among themselves. There is an Occupational Health and Safety Team at Olkiluoto. It consists of occupational safety representatives, representatives of the various Business Units, and representatives of the occupational health care organisation. The comprehensive composition of the Team is designed to ensure that the Team represents the entire personnel (100%).

The Company Management carries out a management review of the effectiveness of the occupational health and safety system twice a year. The Management specifies Company-level objectives for health and safety operation. Health and safety management is in the Management Group represented by the Senior Vice President, Safety. Once a month the management carried out a safety round in a pre-agreed area, and the observations made during the rounds were recorded in the electronic data system of quality management for further actions, if required. The development of health and safety is also monitored by the Board of Directors of the Company.

The objective set for the year 2017 was to decrease the overall accident frequency rate in Olkiluoto from the 20% target value of the previous year, which equals 4.0 accidents or less per one million working hours. This objective applies to the personnel of TVO, Posiva and the contractors working in Olkiluoto. Another objective was for every employee of the TVO Group to make two safety observations during the year, which means the total number of safety observations that was to be achieved was ca. 1600.

Occupational safety and safety culture programmes were prepared to ensure the achievement of the objectives. The main approaches described in the occupational safety programme of 2017 included the use of preventive tools, risk identification carried out on the work point, and inspection rounds in the individual’s own work environment. The use of preventive tools was designed to impact the accident frequency rate through prevention. The achieved results have for both development programmes been measured with safety indicators and reported in the safety monitoring reports. The target level was not achieved in the accident frequency rate, as the rate was 6.0 in Olkiluoto in 2017. This figure includes TVO personnel, Posiva personnel and all contractors active in Olkiluoto, with the exception of the OL3 site which is reported by the AREVA-Siemens Consortium. The number of safety observations met the target number, but coverage was only 75.6 percent.

The Company management has specified the objectives for 2018 in connection with strategy planning. Occupational health and safety is part of the safety strategy planning. The Company-level objective is to decrease the combined accident frequency rate in Olkiluoto by 20% from the objective for 2017, which equals 3.2 accidents or less per one million working hours.

Health and safety cooperation with contractors

In 2017, cooperation in the field of occupational health and safety was intensified with contractors who had reported injuries in 2016. Four contractors were placed under intensified monitoring. A programme was set up for them focusing on the use of preventive tools, reporting and follow-up. For two of the four monitored contractors, the number of injuries decreased from the previous year and one of them achieved a zero target. For the other two contractors, the number of injuries remained unchanged, or increased. Preventive tools were used adequately in terms of numbers, but were not yet established in systematic use. Monitoring of these contractors will be continued also in 2018.
