Abstract
This work aimed to identify harmful factors in the production environment, identify risk
factors, and assess their impact on the health of workers of the Ferghana Oil Refinery Plant. The
research was conducted in 2010-2014 at the Fergana Oil Refinery. Sanitary and hygienic, labouratory,
calculation and statistical methods of research were used to achieve the goal. The research results
showed that the activity of professional groups of the main production shops of the refinery is
accompanied by an unfavourable impact of a complex of factors of the production environment and
labour process. The workplaces of these categories of specialists correspond to the general class of
working conditions according to the hygienic classification - 3 class 1, 2, 3 and 4 degrees (3.1, 3.2,
3.3, and 3.4), where the high level of gas pollution, industrial noise and vibration, the severity of the
labour process is observed. The technological cycle of production, consisting of sequential production
operations, based on a multistage chain of chemical reactions, allowed identifying one of the leading
harmful production factors - chemical. The composition of chemical pollutants of the working zone
included a wide range of gases and chemical substances: carbon monoxide, sulphur dioxide, hydrogen
sulfide, chlorine, toluene, benzene, acetone, hydrocarbons, kerosene, mineral oils, phenol, sulphur oil,
gasoline, methylethyl ketone, diesel fuel. Thus, based on the obtained research results, the nature and
intensity of unfavorable production factors have been revealed, the level of professional risk for the
employees' health has been assessed, the risk factors determining the employees' professional health
have been identified, the priorities in implementation of preventive measures at the enterprise have
been determined.
