چکیده مقاله :
Examining the records of accident analysis shows that so far more direct and indirect causes of accidents have been dealt with and more rooting has not been done in the field of revealing the hidden causes of accidents. Unfortunately, most of the shallow analyzes of accidents focus on the obvious causes of accidents. If in the next steps it is necessary to identify the hidden causes of accidents that are usually hidden from the eyes of non-experts. In this article, while considering the obvious and hidden causes of accidents, the evaluation of two accidents that happened in the electricity distribution company of Chaharmahal and Bakhtiari province is discussed. By drawing the tree of each incident, the percentage of frequency of the causes of each incident is calculated. The results are as follows: Non-observance of safety principles with the highest percentage of frequency (66%) had the greatest impact on the occurrence of these accidents. The lack of supervisor supervision and non-observance of training have played a role in the occurrence of these incidents with the same percentage of frequency (33.3%).
