Introduction. Effective occupational health and safety education plays an important role in the prevention of workplace accidents and work-related illnesses. In 2017, there were 23,387 occupational accidents resulting in incapacity for more than 3 working days and 281 suspected occupational diseases in Hungary. A significant part of these occurred in the manufacturing industry. Objective.

Methods. A questionnaire survey was conducted among the employees of a medium-sized manufacturing company. Of the 83 employees, 72 participated in the study. Workers completed an anonymous questionnaire consisting of 24 questions that covered, in addition to demographic characteristics, occupational health and safety training, situation of health and safety at work, preventive measures, occupational accidents and work-related ill health. Data were processed in a descriptive manner and by inferential statistical analysis. Results. In the survey, the employees reported about having attended regular occupational health and safety trainings, understanding what they have been taught and being familiar with their health and safety tasks, although some shortages in the effectiveness of the education, especially the limited practice, have been identified.

Four of the respondents had work accident at their current workplace, and three people experienced ill health that they related to work.

In addition, the use of dangerous equipment, the modernity of work equipment, and the attention of the employer to health and safety at work correlated significantly with the employees? perception how much they considered their workplace to be harmful to health.
