Risk assessment of unsafe behaviors among workers of a mining company in Sirjan city in 2026

Introduction: Unsafe behaviors are one of the most important factors in occupational accidents in high-risk industries, and risk assessment of these behaviors plays an important role in accident prevention. Despite the development of various risk assessment methods, the uncertainty in the analysis of unsafe behaviors has not yet been fully addressed. Therefore, the present study aimed to provide a quantitative model for assessing the risk of unsafe behaviors using Monte Carlo simulation in the mining industry. Materials and Methods: This study was conducted in a descriptive-analytical manner in a mining industry. Data were collected through a questionnaire designed based on individual and organizational factors affecting unsafe behaviors. After calculating and normalizing the factor scores, the probability and severity of the risk of unsafe behaviors were estimated using Monte Carlo simulation and the presented quantitative model. Results: The results showed that 62.1% of behaviors are unsafe. Accordingly, welders and mechanics had the highest level of risk of unsafe behaviors. Also, safety culture and safety awareness were identified as the most important factors in reducing unsafe behaviors. Simulation results showed that increasing organizational and individual safety factors can reduce the likelihood of unsafe behaviors. Conclusion: The results of the study showed that unsafe behaviors were significantly prevalent among workers employed in mining activities and those workers in the welding and repair sectors had the highest risk of unsafe behaviors. Also, organizational factors, especially safety climate and safety management system, played a more effective role than individual factors in the occurrence of unsafe behaviors. Therefore, strengthening safety culture, improving supervision, and implementing behavioral safety-based interventions can be effective in reducing the likelihood of occupational accidents in mining industries.
