Analysis of the Impact of Violation of Safety Requirements on the Occurrence of Accidents at Enterprises of Main Gas Transportation

The procedure of behavioral safety audit has successfully established itself in the practices of Russian and international companies in various industrial sectors. When conducting a behavioral safety audit, an auditor compares the observed conditions and employee’s actions with the established classifier based on the behavioral safety audit results report. In order to determine the relationship between hazardous actions of employees and dangerous conditions at their workplaces with the potential severity of accident consequences, a retrospective analysis has been conducted for the study, where the root causes of 411 accidents that occurred at main gas transportation enterprises have been compared with violations of safety requirements using 33 criteria of the behavioral safety audit. During the discriminant analysis, canonical discriminant functions and centroids have been determined, the coefficient of canonical correlation and the values of Wilks' lambda criterion and F-criterion have been calculated, and standardized and structural coefficients have been identified. As a result of the study, 10 criteria of the classifier of the behavioral safety audit have been detected, whose violation significantly affects the determination of the potential severity of accidents; the degree and conditions of such impact within the context of the examined selection have been established and substantiated.
