Investigations of accidents in industry have shown that various factors affect the occurrence of accidents. Therefore, the aim of this study was to investigate the relationship between the prevalence of occupational accidents with individual and occupational factors in the industrial work environment of Qom province.

This descriptive study was performed based on the incidents registered in the Labor Inspection Office of Qom Province in 2017. All cases were selected and 1048 cases were reviewed according to the accurate registration of incidents. Necessary parameters were extracted from accident reporting forms and their frequency and frequency percentage were analyzed by SPSS 18 software.

The highest number of accidents was in the age range of 20-30 years with less than 5 years of work experience. The lowest number of accidents was related to bachelor's degree and higher. In addition, a high number of victims (41.5%) were involved in construction activities. In the study of the working population, the highest number of accidents was related to workshops with a staff number of 10-24. In investigating the causes of accidents, 33.2% of accidents were identified as lack of safety training and 24.2% as lack of safe work procedures. In the group of equipment causes, the highest share of accidents was due to the lack of proper equipment and in relation to human causes, the main reason for the accident was the non-stopping of the device during repair.

The results of the present study showed that demographic and occupational factors, such as age, work experience, and type of industry were very important in the occurrence of industrial accidents. In addition, it was found that managerial, equipment and human causes each have an effective role in the occurrence of accidents, which can be significantly reduced using more supervision by managers and recruiting safety and health officials, and finally observing safety principles in all areas of work.

Analyze the causes of accidents to control and prevention of accidents is necessary.This study was conducted to analyze the causes of disability accident in a dam construction project using Tripod Beta-SCAT combination method.

A critical event was selected and the causes were identified, employing Tripod Beta-SCAT method. In this sense,first, interface causes and root causes obtained by the Tripod Beta method. Then, the obtained causes and the control measures were placed in SCAT table. The effect of causes of accidents and their ranking were determined using Chi-Square Test and Friedman test, respectively. Accordingly, appropriate control measures and necessary suggestions were provided.

underlying cause were identified in 6 classes. Maintenance management ( 25%) and training (20%) had the highest rank and executive instructions (5%) had the lowest. 13 preconditions were also identified. Most important indirect cause was "the inappropriate machine lifting factor (2.69)". Most important root cause was "the erosion and excessive deterioration of the mechanical excavator (4.55)". Furthermore, the most important control measure was “the inspection and control of the operation (5.05)". There was also a significant relationship between indirect and root causes (significance level 0.001 and correlation coefficient 0.608).

Combined method presented in this study has in many cases met the needs of different organizations and is currently one of the most important methods for analyzing the accidents causes. The combination of SCAT with other methods will be useful for analyzing the causes of other accidents on dams and construction projects.
