Introduction: Many safety accidents in various industries are caused by poor safety culture of employees. Therefore, safety training can play an essential role in reducing workplace accidents and any damage to students. According to the importance of university workshops, the purpose of this study was to identify and assess the safety and health risks of the foundry and machinery workshops of Iran University of Science and Technology.

Methods: This descriptive study was conducted at Iran University of Science and Technology in the 2018. After identifying risks, the Fuzzy Failure Modes and Effect Analysis (FMEA) technique was used to identify and assess the RPN number of risks which is calculated by multiplying of Severity x Occurrence x Detection and all risks were prioritized based on the calculated RPNs. Finally, corrective actions are presented to reduce injury risks.

Results: The RPN range of 10 potential hazards in the machinery workshop calculated from 5.8 to 230.3, and the RPN range of 19 potential hazards in the foundry workshop calculated from 1.3 to 665.3. The danger of " throwing lathe chuck wrench " with RPN=230/33 in machinery workshop and "melt throwing due to air retention in metal parts " with RPN=665/33 in foundry workshop received the top priorities.

Conclusion: Based on the calculated results, it is expected that the implementation of proposed corrective actions and the development of educational programs to promote students' safety culture can reduce the level of existing risks significantly.
