What is Suppressall™ and how does it work
The National Fire Protection Association (NFPA) defines condensed aerosol as "A fire suppression medium composed of finely divided solid particles and gases, generated by the combustion of a solid aerosol-forming compound".
What is Suppressall™ Aerosol
Suppressall™ Aerosol utilizes a solid chemical compound that, when activated, releases billions of microscopic particles into the air to extinguish fires.
These particles, composed of potassium salts and propelled by gases like nitrogen and carbon dioxide, create an atmosphere that prevents combustion.
The particles suppress fires through several mechanisms:
- Disrupting the chemical reaction: By removing oxidants, they most effectively halt the burning process.
- Cooling the flame: The particles envelop the fire, absorbing heat through their vast surface area.
- Preventing radical recombination: The resulting atmosphere inhibits "free radicals" from sustaining the fire.**
**Suppressall™ works simultaneously on three components of the fire tetrahedron; heat, fuel, and the chemical reaction while oxygen levels are unaffected.
During combustion, free radicals and unstable atoms are formed. This elemental formation allows fire to exist.
Performance of Suppressall™ Condensed Aerosol
Attacking all elements of the fire tetrahedron, Suppressall™ Condensed Aerosol suppressants are highly effective. Some can extinguish a Class B flammable liquid pool fire with 1/5 the amount of Halon 1301 or 1/10 the amount of HFC or FK-based clean agents, in terms of kg agent/m3.
Extinguishing performance depends on aerosol particulate density near the flame. Faster agent build-up around the flame increases efficiency. Extinguishing and design densities are expressed in g/m3. Efficiency varies by factors like aerosol location, proximity of other combustibles, and fuel type.
