During gas transportation operations in extreme low-temperature natural and climatic conditions of the Far North, one of the urgent issues is the assessment of the probability of personnel death in the event of emergencies and occupational diseases during regular operation when operating the technological equipment of the compressor stations of main gas pipelines. The article discusses the results of an assessment based on the developed methodology for calculating integral indicators of the risk of damage to the life and health of employees of the compressor stations of main gas pipelines in the conditions of the Far North, aimed at ensuring the safety of personnel in the workplaces.
When creating the methodological approach, specific features affecting the level of safety of life and health of personnel were considered, such as: microclimate, the mechanism of brittle destruction of equipment metal, temperature inversion, prolonged exposure to aggregates noise, etc. To determine the influence of each of the listed factors, a single criterion for assessing damage to the health of personnel (days of under-living) located directly at the investigated hazardous production facility (compressor stations of main gas pipelines) was selected and justified: machinists, automation and metrological support fitters, repair fitters. Based on the statistical data, the damage of under-living to retirement age is determined, adjusted for the conditions of the Far North in the event of the death of an employee of each profession in the event of an emergency at a compressor station. Further, in the range from the beginning of employment to the estimated age of death calculated above, the damage from occupational diseases is determined.
These provisions of the methodological approach for assessing the cumulative damage to health allowed to develop recommendations for calculating insurance payments in the event of the death of an employee, calculating additional payments for harmful and hazardous working conditions and design changes in the form of the use of special coatings for pipelines for reducing the occupational risk of personnel of the compressor stations of main gas pipelines in given conditions.
