Assessment of labor conditions of working drilling units for oil production

Abstract

Introduction. During oil production, drillers are exposed to harmful occupation production factors: noise, vibration, the severity and intensity of work, microclimatic conditions, oil, and components. The purpose of the study was to conduct comprehensive investigations of working conditions and health status, to assess the occupational risk of drillers at an oil production enterprise. Material and methods. The work was carried out within the framework of the special assessment of working conditions carried out according to the plan. The influence of occupational factors of the production environment on workers’ health was assessed by indices of occupational morbidity and the results of periodic medical examinations of drillers servicing the drilling rig for oil production driller 5000.320 ERO for the period 2013-2018. Results. Analysis of the measured parameters of harmful occupation factors indicates noise, vibration, and psychophysiological indices to be the leading indices of working conditions that affect the employees’ health. The general assessment of employees’ working conditions corresponds to the class- 3.3 (harmful), the category of occupational risk - high (unbearable). The source of harmful effects on workers is the equipment of the drilling rig 5000.320 ERO. Analysis of medical documents drillers over 5 years revealed a link between working conditions and the development of occupational diseases (vibration disease, sensorineural hearing loss); between operating conditions and the development of career-related diseases: musculoskeletal system (arthrosis, arthritis, osteochondrosis, etc.); the peripheral nervous system (radiculitis, plexitis, polyneuritis, etc.); diseases of the respiratory system (bronchitis, pneumonia, asthma, and respiratory diseases, etc.). Conclusion. To prevent the negative impact of harmful production factors at the enterprise it is necessary to provide many preventive measures: automation, mechanization, sealing of equipment, employees have to be equipped with personal protective equipment, improving the quality of preliminary and periodic medical examinations.
