Risk Mitigation Highest Risk Level (Red Zone) Based on Hazard Identification Risk Assessment And Assessment (Hirarc)

Abstract

The rate of work accidents in the mining industry is still relatively high despite the implementation of various safety systems. Coal transportation activities with heavy equipment and extreme road conditions are one of the main contributors to the risk of fatal accidents. This study aims to identify and evaluate the risks that are classified as very high at PT. XYZ uses the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) method, and formulates mitigation strategies in the form of preventive actions and contingency plans to reduce risk levels and maintain the company's operational sustainability. Through risk assessment using a matrix, 21 risk variables were found to be categorized as very high (red zone), with the two main risks being slippery roads during rain and operators not knowing the landslide zone. The cause analysis was conducted using a fishbone diagram, and then mitigation measures were developed based on the risk control hierarchy. The results showed that the integrated implementation of technical and administrative controls and the use of personal protective equipment can significantly reduce potential hazards. This study concludes that systematic risk management through the HIRARC approach is effective in mapping hazard priorities and determining appropriate mitigation measures. The main recommendations are aimed at improving engineering controls, operator training, and emergency response plan readiness to prevent future work accidents.
