Abstract With the increase in the importance given to occupational health and safety, the importance given to occupational safety training has increased. Many studies on the causes of occupational accidents indicate that there are cases called "unsafe behaviors" that are caused by the individual mistakes of the employees at a rate of 80-90%. Efficient occupational health and safety training is an important issue that needs to be emphasized in order to correct the mentioned individual mistakes and reduce occupational accidents and diseases. In this study, in order to increase the efficiency of occupational safety trainings, trainings in different structure were applied to 3 working groups consisting of 50 people with the same number and similar quality. The first group was given job-specific training in the office, the second group was given job-specific toolbox training in the working area, the last group was given both job-specific and job-specific toolbox training. After the trainings, instead of multiple-choice exams, infographic drawing surveys containing job-specific hazards were applied to the personnel, and the change in the hazard perceptions of the personnel according to the trainings of different structures was determined. SPSS 22.0 program was used in the statistical analysis of the data obtained in the study. According to the results of the analysis, it was concluded that coeducation was more effective in increasing the danger perception of the personnel compared to the other two types of education. Also, the groups that need to be specially trained are classified according to their demographic characteristics.
