Abstract

Introduction: It is necessary to pay attention to the key role of chain dry boom crane in heavy industrial projects such as the steel industry, to identify and manage occupational risks related to it. This study was conducted with the aim of identifying, evaluating, and managing job risks associated with chain dry boom cranes in the Yazd Alloy Steel Oxygen Plant project using the HAZID technique and providing control strategies to reduce the risk level.

Materials and Methods: This study was conducted qualitatively using the HAZID technique. The statistical population included 50 operators, managers, and project experts, and the required information was collected through semi-structured interviews and HAZID workshops. Identified risks were classified into three categories: technical, environmental and human and were evaluated using the risk matrix. Control measures to reduce risk were also proposed and implemented.

Findings: In this research, occupational hazards associated with dry chain cranes were identified and classified into three main categories including technical hazards (40%), environmental hazards (30%) and human hazards (30%). Failure of hydraulic systems, failure of boom and safety equipment were considered as technical risks, dealing with high voltage power lines and inappropriate weather effects as environmental risks, and use of unauthorized operators and ignorance of safety principles were considered as human risks.

Conclusion: The results of this research showed that after the implementation of control measures, the level of risk decreased significantly. Applying the HAZID technique in similar industrial projects can improve safety and prevent accidents by accurately identifying risks and providing preventive solutions.
