RadEX vs. a Market-Leading Certified Fire Suppression System
Government-Supervised Comparative Testing – Finland, March 2025
Test Date: March 26, 2025
Location: Finnish National Fire Academy, Kuopio
Report No.: 2025-133

Client: Impulse Storm Ltd. (United Kingdom)
In March 2025, the Finnish National Fire Academy conducted an official comparative test of two condensed aerosol fire suppression systems:
- RadEX – an innovative prototype developed by Impulse Storm Ltd., currently in the final engineering refinement phase.
- Benchmark System – a commercially available, market-leading aerosol unit holding top-tier international certifications (UL (USA), the United Kingdom, and the European Union) and authorized for use in occupied residential and public buildings across both the EU and the USA.
Purpose of the Tests:
To assess toxic gas emissions (CO, NO), oxygen depletion (O₂), and airborne particulate concentration following activation, under realistic fire conditions.
Key Findings:
- Extinguishing Performance:
Both systems extinguished the fire in 2–3 seconds. However, RadEX achieved this using 13 times less active compound, offering a 13x advantage in extinguishing efficiency, material usage, logistics, and disposal. - Carbon Monoxide (CO):
- Benchmark system: up to 8000 ppm
- RadEX: maximum 590 ppm
→ RadEX is 13.5 times safer
- Nitric Oxide (NO):
- Benchmark system: up to 960 ppm
- RadEX: maximum 180 ppm
→ RadEX is 5.3 times safer
- Oxygen (O₂):
- Benchmark system: dropped to 18% – the hypoxia threshold
- RadEX: 0% oxygen reduction – oxygen levels remained stable at 20–21%
→ RadEX fully preserves breathable air
- Aerosol Particles (Dust Load):
- Benchmark system: up to 7.2 g/m³
- RadEX: maximum 2.0 g/m³
→ RadEX reduces airborne contamination by over 3.5 times
Official Conclusion:
The tests confirmed that the benchmark system, despite holding international certifications, produces toxic emissions that exceed globally recognized danger thresholds, including IDLH and AEGL-3 limits for both CO and NO. This raises serious concerns about the credibility of its certifications and its legal use in human-occupied environments.
In contrast, RadEX, even in prototype form, demonstrated:
- Toxicity levels up to 14 times lower,
- Zero oxygen depletion,
- 13 times higher extinguishing efficiency.
RadEX represents a new generation of fire safety.
It does not just meet regulatory paperwork — it delivers real protection, complies with modern health and environmental standards, and is ready to replace outdated and potentially lethal technologies.
