Background:
Hospitals are considered one of the most important institutions providing health services; given the presence of specific hazards, compliance with safety principles is of utmost importance. This study aimed to identify and evaluate the risk of existing hazards using the Energy Tracing and Barrier Analysis (ETBA) method in the imaging department.
Materials And Methods:
The present study is an analytical study performed to assess the risk in the imaging department of Amir al-Momenin Ali (AS) State Hospital in Gerash in 2024. In this study, potential risks were identified using the ETBA technique and qualitatively assessed via the risk matrix (MIL-STD882E). Observation, interviews with department experts, review of documents, work instructions, technical documents of devices, layout of devices, as well as documents of the maintenance and repair unit of this department were used for data collection.
Results:
A total of 433 risks were identified, 232 of which were human-related, 167 were equipment-related and 34 were environmental-related. At the primary risk level, 13 were identified as unacceptable risks (high level) requiring immediate intervention, 281 as undesirable risks (serious level), 79 as acceptable risks with revision (medium level), and 61 as acceptable risks (low level). At the secondary risk level, once the controls were implemented, the results improved and the number of undesirable risks dropped to 18, 274 as medium level, and 141 as low level, demonstrating the effectiveness of the controls in mitigating risks.
Conclusion:
In this study, in addition to obtaining the level of risks in the hospital imaging department, the level of possible risks in each of those departments was also measured. Further, based on the existing assessment levels, control measures and suggestions were presented. They included implementing measures such as safety training, periodic inspection monitoring system, operator training, protection control, cable inspection, installation of overload alarms, improving preventive maintenance, as well as providing appropriate educational solutions to control the identified risks.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
