RedextendeR Problem & Context: Suicide by jumping is a critical public health crisis. Currently, emergency services rely on inflatable air cushions to intercept falls, but these face severe operational gaps: they are often unusable due to urban obstacles (furniture, trees, vehicles) or complex terrain. Furthermore, in high-rise incidents (above 10 floors), air cushions reach their physical limit, resulting in minimal survival rates due to extreme impact forces. The Innovation: RedextendeR RedextendeR is a patent-pending rapid-deployment rescue system designed "by firefighters for firefighters." It shifts the paradigm from ground-level interception to point-of-incident protection. By deploying a lightweight, foldable safety net just one floor below the victim, it drastically reduces free-fall distance and kinetic energy. Capability Gaps Addressed: Force Mitigation: Intercepting the fall early ensures controlled deceleration through a specialized dynamic safety chain with integrated energy absorbers. Urban Versatility: Deployed from within the building, RedextendeR is immune to street-level obstacles or building geometries that block traditional equipment. Responder Safety: It eliminates the risk of the victim falling onto the rescue team. Deployment is performed "under cover" from indoors, safely out of the vertical fall trajectory. Precision Engineering: Features unique Z-shaped telescopic poles for maximum lateral coverage and an anti-pendulum line to prevent impacts against the facade. Standards & Reliability: The system integrates components meeting rigorous European safety standards: UNE-EN-1263-1 & 2 (Nets), CE-EN-355 (Absorbers), UNE-EN-795B and CE-EN-362 (Anchors/Connectors). It is currently moving from TRL 6 toward full industrial implementation and joint certification.

Objectives: The primary goal of this proposal is to transition RedextendeR from its current validated state (TRL 6) to a fully industrialised, market-ready solution (TRL 8/9). Specifically, we aim to: Industrialise Production: Leverage i4Sistemas' engineering expertise, ISO 9001 standards, and their "Innovative SME" capabilities to optimise manufacturing, ensuring scalability for mass adoption by European emergency services. Achieve Full Certification: Finalise the comprehensive joint certification of the system, ensuring it meets all European safety and performance standards for rescue equipment. Operational Implementation: Conduct final pilot testing with frontline firefighting units to refine deployment protocols and training modules. European Dissemination: Establish a roadmap for international distribution, using the DIREKTION framework to showcase the solution in Germany and Brussels. Relevance and Validation: RedextendeR addresses a critical Capability Gap in urban resilience. The project’s relevance has already been recognised by the professional community; it was successfully presented and discussed in a dedicated workshop during the 29th ASELF National Congress (Málaga, November 2025). This presentation before Spain's leading fire and rescue association provided vital expert feedback, confirming the urgent need for such a tool in modern emergency portfolios. By bridging the gap between innovative engineering and frontline reality, RedextendeR offers: Increased Survivability: Drastically reducing fall energy translates directly into lives saved in high-rise incidents where traditional air cushions fail. Responder Safety: It mitigates the risk of the victim falling onto the rescue team by allowing "under cover" deployment from within the building. Strategic Autonomy: Providing a lightweight, EU-manufactured, and high-tech alternative to heavy equipment, strengthening the operational capacity of European first responders.
Innovation: A Paradigm Shift in Life-Saving Technology 1. Architectural Innovation: Point-of-Incident Protection RedextendeR introduces a disruptive paradigm shift by moving fall protection from the ground to the point of incident. By deploying the system just one floor below the victim, we minimize free-fall distance. This is critical because kinetic energy increases quadratically with fall height; reducing this distance fundamentally changes the physics of the survival outcome. 2. Dynamic Energy Management Unlike static nets, RedextendeR utilizes a multi-stage dynamic chain designed for controlled deceleration: High-Tenacity Nets: Engineered for initial impact through elastic deformation. Sequential Energy Absorbers (CE-EN-355): They ensure the "Force of Shock" remains below human injury thresholds, even in high-altitude scenarios. Z-Shaped Telescopic Engineering: Developed with i4Sistemas, these custom poles allow maximum lateral expansion from a single opening, creating a wide catchment area from the building's interior. 3. Anti-Pendulum Control System A key innovation is our integrated anti-pendulum line. In standard falls, the "pendulum effect" often causes the victim to strike the facade after the initial catch. Our system cancels this vector, keeping the victim in a safe, neutral zone for immediate medical access. 4. Operational Agility & Safety The system enables a 90-second "under cover" deployment. Firefighters work from within the safety of the building, eliminating the "target-risk" (victim falling onto rescuers). This is a major leap in occupational safety. 5. Maturity & IP Backed by a patent-pending status, this solution has moved from theory to a TRL 6 functional reality, validated by professional fire services at the ASELF National Congress.
Closing the Gap in Crisis Intervention RedextendeR addresses critical failures in the operational capacity of European First Responders (FRPs) during high-altitude suicide attempts and falls, resolving three fundamental "bottlenecks": 1. Eliminating Environmental Constraints Standard protocols rely on inflatable cushions requiring a large, flat, and unobstructed "footprint". In dense European urban environments, street furniture, parked cars, trees, and narrow sidewalks often make deployment impossible. RedextendeR resolves this by de-linking the rescue system from ground conditions. As a facade-mounted device, it operates regardless of street-level obstacles, ensuring rescuers always have a viable tool, no matter the urban layout. 2. Overcoming the "Height-Energy" Barrier The operational limit of traditional equipment is reached quickly in high-rise buildings. Beyond a certain height, impact energy exceeds the physical capacity of ground cushions. RedextendeR resolves this by shortening the fall trajectory. By installing the device just one floor below the victim, we maintain the impact force within survivable limits. This extends the operational reach of fire services to any floor of a skyscraper, providing a capability that currently does not exist. 3. Drastic Reduction in Response Time In suicide interventions, every second is critical. The logistics of moving and inflating large cushions can take several minutes. RedextendeR’s 90-second deployment allows an almost immediate response once the anchor point is set. This speed resolves the "vulnerability window" during which the victim might jump before safety measures are ready. 4. Occupational Risk Mitigation Current methods often place rescuers in the "fall zone" during equipment positioning. RedextendeR enables "under-cover" operation: personnel work from the interior of the floor below, protected by the building’s structure, eliminating the risk of the victim or debris falling onto the team.
