The State Fire and Rescue Service (SFRS) plays a crucial role in Latvia’s internal security system and operates as a key component of the European Union Civil Protection Mechanism. Ensuring the reliability of self-contained breathing apparatus (SCBA) is vital for firefighter safety and operational effectiveness. However, the continued use of outdated testing equipment (Labtest 250, ProfiCheck) and decentralized maintenance documentation delays defect detection and increases service costs. This study evaluates current SCBA maintenance practices at SFRS and investigates modernization opportunities through the integration of SmartCheck automated diagnostics, TecBOS.Tech digital tracking software, and centralized maintenance record systems. The applied research methodology comprises quantitative data analysis (2020-2024) of technical reports and maintenance indicators, experimental performance comparisons between SmartCheck and Labtest 250 testing methods, and expert consultations with SFRS technicians and SCBA industry specialists (MSA, Dräger). Experimental results demonstrated that SmartCheck reduced the time required for defect detection by 35%, improved diagnostic accuracy from 78.4% to 93.2%, and extended SCBA service life by 20%. Additionally, the use of TecBOS.Tech is projected to reduce maintenance costs by up to 15% through optimized planning and real-time defect tracking. These findings suggest that integrating automated diagnostics, IoT monitoring, and AI-driven maintenance algorithms would significantly enhance the reliability, efficiency, and responsiveness of SFRS equipment management. As SFRS is integrated into the EU Civil Protection Mechanism, such advancements align with broader regional objectives in emergency preparedness and resilience.
