Slip, trip, and fall (STF) incidents are among the most common occupational accidents in industrial settings. One preventive effort undertaken by companies is providing occupational health and safety (OHS) communication media. This study aims to analyze the influence of OHS communication media on workers’ safe behavior in preventing STF at CV Cita Nasional. This quantitative study used a cross-sectional design involving 52 workers selected through purposive sampling. Data were collected using a Likert-scale (1-4) questionnaire measuring seven variables: STF Understanding, OHS Media Availability & Distribution, OHS Media Quality, Communication Intensity, OHS Media Understanding, Work Environment Condition, and Safe Behavior. Data analysis included validity and reliability testing, descriptive statistics, Pearson correlation, and multiple linear regression using SPSS. Results showed all questionnaire items were valid and reliable (Cronbach's Alpha 0.783-0.921). Multiple regression analysis revealed that STF Understanding, Communication Intensity, OHS Media Understanding, and Work Environment Condition significantly and positively influenced Safe Behavior (p<0.05), with OHS Media Understanding as the strongest predictor (Beta=0.383). The regression model explained 68.1% of the variance in Safe Behavior (R²=0.681; F=16.018; p<0.001). A total of 61.5% of respondents had experienced or nearly experienced an STF incident, yet 81.6% of these incidents were not reported. This study recommends improving workers’ understanding of OHS communication media and strengthening incident-reporting culture as efforts to prevent STF in the workplace.
