The work aims to study peculiarities of assessing occupational risks of injury to workers during when spraying agricultural crops. The list of possible risks of threats caused by the probable poisoning of workers with pesticides, injury by the tractor operating bodies, sprayers and machines for mixture preparing, as well as injury to workers due to the action of other dangerous factors, is substantiated. The level of risk of dangerous situations is estimated according to the method of expert assessments, as a product of the indicators of the probability of event occurrence, the severity of injury and the indicator of expert opinion.
The research results indicate that the level of risk of the workers’ pesticide poisoning of workers, injury by the operating bodies of a tractor, sprayer and machines for working mixtures preparing, as well as injury to the worker due to the action of other dangerous factors is average. It is revealed that the degree of the basic risk of occurrence of a dangerous situation of poisoning an employee with a pesticide is 36 points, injury to an employee by the working bodies of a tractor, sprayer and machines for working mixtures preparing is 27 points, and injury to an employee by other dangerous factors is 18 points. Therefore, additional protective measures should be used to reduce the level of danger.
Additional organizational and technical measures to protect against hazards are substantiated, namely, medical examination before every shift, need to reserve the personal protective equipment, use of additional equipment for operational control of meteorological conditions and a navigator to control the modes of movement of the unit and prevent its damage by obstacles on the field, etc., which reduce the probability of injury to workers. The use of proposed precautionary measures will make it possible to minimize threats to the workers’ health during the chemical protection of plants by spraying.
