  • Abstract

    Controlled descent devices are critical safety mechanisms designed for emergency rescue, enabling the safe descent of individuals from significant heights during emergencies. This study presents an analysis of risk mitigation strategies for a controlled descent device working on centrifugal braking mechanism. The study adopts a Design Failure Mode and Effects Analysis (DFMEA) approach to systematically identify, evaluate, and prioritize potential failure modes and their effects on device functionality and user safety. By implementing DFMEA, this research aims to mitigate risks associated with component failures, structural integrity, thermal stresses, and braking performance, which are critical for controlled descent technology. Key areas of focus include the braking system’s ability to maintain a controlled, consistent descent speed under varying load conditions, durability and wear resistance of materials, and response to extreme environmental conditions. Findings from the DFMEA, guides design improvements and operational recommendations, highlighting essential mitigations such as material selection for high wear resistance, redundancy in braking components, and rigorous testing for thermal and mechanical resilience. This comprehensive risk assessment ensures the reliability of the controlled descent device, providing valuable insights for manu-facturers and safety personnel dedicated to advancing the emergency rescue technology.
