Abstract:

Functionality, reliability and safety of complex technological systems consisting of elementary components are determined by their quality service. The conditions for good quality service of the facility are adequately prepared internal regulations, technological procedures and the implementation step process in which human factor contributes. The paper describes an example of the real process of workers during reparation of the electric engine in the nuclear power plant. The method of the partner control during controlled operation the fulfillment of the principles of safety at work by independent observer was evaluated. The aim was to identify human error factor. Couching and observation were used as tools to identify the deviations from the standard procedure when repairing the electric engine. Human factor errors were identified. The measures for applications of the tools to prevent human errors were set up on retraining and self-perception of the incorrect procedures of the employees due to objective and subjective reasons. The implementation of methods of the effective couching and the control from the management are the measures in the area of nuclear power stations and, thus, they lead to achieve desirable behavior change and awareness of the personal responsibility for quality and safe work performed by the staff.
