Net een mail terug gekregen van elise-shop.com (Moordrecht) over de Vuureter!
Lijkt me handiger dan een 15kg Co2-blusser in je auto!
Hierbij een tekst van de fabrikant van dit produkt met een uitleg:
The environmentally-safe fire suppressant 8B
The flame suppressant Fireater is a manual, portable extinguisher with remarkable extinguishing capability. It is non-toxic and environmentally safe.
Fireater is a small, compact, lightweight cylinder that is 10 inches long, 1.2 inches in diameter and 0.6 pounds in weight. The upper part of the device is a metal tube containing the extinguishing charge. The lower part of the device is composed of plastic and serves as a support handle.
When activated, the powerful extinguishing charge produces a potassium (aerosol) jet that lasts more than 50 seconds. This activation time is very long, especially when compared to industry standards. The following shows industry standard minimum charge times for fire extinguishers of different weights:
Less than 3 kg, 6 seconds (less than 6.6 pounds: 6 seconds)
3 – 5 kg, 9 seconds (6.6 pounds – 11 pounds: 9 seconds)
6 – 10 kg, 12 seconds (11 pounds – 22 pounds: 12 seconds)
> 10 kg, 15 seconds (more than 22 pounds: 15 seconds)
Fireater More than 50 seconds
Product specifications
Compared to the new generation of fire extinguishers available on the market today, Fireater is not only efficient, economical and environmentally safe but also distinct in its specific use of Potassium powder as the basis of its extinguishing power.
Fireater is composed of stable, solid minerals; it does not contain gas and is not pressurized. The aerosol-like jet is only produced when the charger is “scratched” with its base.
While the jet produced resembles gas, it is essentially an inert salt that emits gas that is already present in the atmosphere. Thorough testing has been conducted, and the results regarding the potential impact of the product on the environment and users are excellent:
ODP Ozone Depletion Potential = zero
GWP Global Warming Potential = zero
ATL Atmospheric Life Time = zero
Not dangerous to human health
Does not product any “organic accumulation”
Non-toxic
Environmentally safe
Non-corrosive
Technical specifications
The use of a Potassium powder jet – a unique method among fire extinguishers – involves the vaporization of the powder in the environment followed by the condensation of its extinguishing substance. Fireater works by interrupting a fire’s chain of reaction (the “auto-catalyst” of the fire). This method allows Fireater to extinguish all types of fires through a saturation process. Furthermore, its slow bio-degradation in the environment furthers the prevention of subsequent fires.
The extinguishing process involves two different reactions: one is physical and the other one is chemical The physical reaction relates to Potassium’s tendancy to oxidize rapidly in air. When in contact with air, alkaline salts consume great quantities of oxygen, thus depriving fires of oxygen. The granulometry of Fireater has been specially conceived to maximize its fire extinguishing capabilities.
The chemical reaction is created through the stable link between Potassium particles and the fire’s combustion particles.
Effective synthesis of the two reactions Through the two reactions, a quick oxidation process takes place, immediately transforming the jet from a solid state into a gaseous state which frees the potassium particles. These atoms are able to intercept and interrupt any other free particles produced by the fire’s chain reaction combustion process. Potassium has strong inhibitor qualities, due to its weak ionization energies.
Classification
Fireater is able to extinguish fires of different classes:
Class A: Solid material, ordinary combustibles, such as wood, paper, cloth, etc.
Class B: Flammable liquids, such as gasoline, oil based paints, solvents, alcohol, acetone, etc.
Class C: Gaseous category: Gas, methane, ect.
Electrical: electrical equipment
Safety of use
The two components necessary for the ignition of Fireater are placed on opposite ends of the device, rendering accidental ignition during transport and storage impossible. The first component, a dry round area, is protected by a lid, and is at the top of the product. The second component, inserted as a cap in the handle is a scratchable head piece made out of phosphorous.

Voor alle duidelijkheid, dit produkt krijgt in Nederland geen officieele classificatie. De reden hiervoor is dat de blusser niet midden in het proces gestopt kan worden. Dit is een eis in het besluit handblus middelen, vandaar dat de blusser niet als handblusser aangemerkt mag worden.
Grappig genoeg wist men bij TNO wel te melden dat men bekend was met dit principe en verrast waren van de effectiviteit.
