Abstract :

In this research, the risk assessment of this project was performed in apparatus, service, turning, welding and forging units. In the apparatus process, 23 cases of accidents are among the high-risk accidents. The second activity is related to changing tires, the control of which is training and observing distance. The third activity is related to inflating the tires, the control action of which is checking the safety valve of the compressor. After performing the control measures, only three of the activities had a high risk. In the service sector, 58% of activities had a high risk, which after control measures, which reached 33%. In the turning section, 45% of the activities had a high risk, which after zero control measures, this amount reached zero%. The most important accident that can be predicted with a risk number of 25 for the forging and welding part is an explosion and fire near the forging workshop, which can lead to the death of the relevant operator due to the double effect of the fire
