بررسی ساختار فیزیکی و شرایط ایمنی شبکه برقرسانی مراکز انتقال خون با روش ردیابی انرژی و تحلیل موانع.

Background and Objectives Constant control of electrical panels is effective in ensuring the safety of users. This study was conducted during the years 2022-2023 to evaluate their structure in blood transfusion centers by ETBA method. Materials and Methods In this descriptive-analytical study with the ETBA method, the performance and quality of the grounding system, capacitor bank, connections, the location of the panels, the arrangement structure of the components, and their cleanliness and safety in the centers of Kermanshah, Hamadan, Ilam, Sanandaj, Arak, Karaj, Semnan, Bandar Abbas, Sari and Yazd were investigated. The obtained information was analyzed statistically with SPSS 25 software. Results The results showed 74.3% electrical panels with unprincipled volume and distribution of connections, 72.4% due to the selection of inappropriate location and distance from tools and devices, deployment in users' traffic area without provision of fence and safety devices, 70.5% not equipped with warning devices, 43.3% non-standard arrangement, 51.4% insufficient cleaning, 66.3% not having an active earth connection, and 60.3% not having a capacitor bank did not have reliable electrical safety. Conclusions Based on these results, the regular and continuous establishment and implementation of the medical equipment maintenance management system can be a fundamental and effective factor in identifying risks and the pertinent degree of risks and damages in the process of activity.
