Abstract

Functionality, reliability and safety of complex technological systems consisting of elementary components are determined by their quality service. The paper describes an example of the real process of workers during reparation of the electric engine in the nuclear power plant. There was evaluated fulfillment of the principles of safety at work what was done by an independent observer who used the method of the partner control. The aim was to identify human failing factor. Couching and observation were used as tools to identify the deviations from the standard procedure at the electric engine repairing. Several human factor errors were identified. The measures for applications of the tools preventing human failings were set up on retraining and self-perception of the incorrect procedures of the employees due to objective and subjective reasons. These measures should help to achieve desirable behavior change and relevant awareness of the personal for responsibility for quality and safe work performed by the staff.
