This research is practical in terms of its purpose. To conduct this research, a mixed-methods approach (combining qualitative and quantitative methods) with an exploratory design was employed. In the quantitative part, a descriptive survey method was employed, and in the qualitative part, a descriptive-analytical method was used. The statistical population of the qualitative part included theoretical and empirical experts, and according to the saturation principle and the purposive sampling method, 19 interviewees were selected. Also, in the quantitative part, the statistical population included all officials (HSE) in the country's steel industry (530 people), and using the method of calculating the minimum sample size in factor analysis, 223 officials were selected. The data collection method in the qualitative section was semi-structured interviews, and in the quantitative section, researcher-made questionnaires derived from the findings of the qualitative section were used to assess the validity of the model from the perspective of the participants in the qualitative section and also from the perspective of the respondents in the quantitative section, and the validity and reliability of the tool were examined and confirmed in both qualitative and quantitative sections. The data analysis method in the qualitative section included content analysis with MaxQDA-V2018, SPSS-V27, and SmartPLS-V3 software. The competence of officials (HSE) in the country's steel industry factories includes five main parts: "general and professional knowledge", "attitude", "skills", and "psychological and behavioral factors". https://sustainearth.sbu.ac.ir/article_105914_ff4b107fff98bfb6470ab6f23963c084.pdf
