F-500 puts out fires 10 times faster than traditional foams, and encapsulates flammable liquids and gasses rather than just covering them up.

AmerizorbTM is proud to announce the new product we have just added to our premier line of absorbents called F-500 Encapsulator Agent (EA). We are now the Northwest's exclusive dealer of this concentrate which is manufactured by Hazard Control Technologies, Inc. (HCT) headquartered in the Atlanta Georgia area.

F-500 EA is a chemical that replaces hazardous foams for Fire suppression. Unlike many of the fire fighting foams being used today, it is non-toxic and not harmful to the environment, people and wildlife. F-500 puts out fires 10 times faster than traditional foams because it operates very rapidly on a cellular level to encapsulate flammable liquids and gasses, whereas foams simply create a thin wall bubble covering over the flammable materials, which is easily broken or disrupted.

HCT F-500


F-500 EA is the answer to many of today’s firefighting challenges.  In a world where fires have become hotter and more difficult to extinguish, F-500 Encapsulator Agent’s unique capabilities meet those challenges.  First, F-500 EA has a remarkable ability to cool a fire and surrounding structures, with the ability to absorb 6-10 times more heat energy than plain water.  Instead of scalding steam, F-500 EA releases a warm vapor.  Secondly, F-500 EA encapsulates fuels forming micelles or “chemical cocoons” that render the fuel nonflammable and nonignitable.  Finally, F-500 EA interrupts the free radical chain reaction.  Free radicals are unburned gases produced during the combustion process that turn into smoke and soot.  Inhibiting the chain reaction results in less smoke and toxins and increases visibility.

  • Rapid cooling
  • Encapsulates the fuel
  • Interrupts the free radical chain reaction
  • Eliminates almost all cancer-causing toxins in smoke
  • Contains no fluorines (PFOS/PFOA)
  • Produces no scalding steam

F-500 Encapsulator Agent is not a foam, so it contains no fluorines, such as perfluorooctyl sulfonate (PFOS). F-500 EA is 100% biodegradable and is non-hazardous, containing no ingredients reportable under the Superfund Amendments and Reauthorization Act (SARA) Title III, Section 313 or the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). Shelf life is 15 years and it can be discarded as a non-hazardous waste under RCRA CFR261.

These unique properties make F-500 Encapsulator Agent the most versatile firefighting agent available.  Where foam has to form and maintain a perfect blanket to separate a fire from oxygen, F-500 EA merely needs to contact the fuel and vapors.  F-500 EA is perfect for three-dimensional fires, plus F-500 EA is recommended for Class A, Class B (polar and nonpolar), Class K and Class D fires.  There’s no need to inventory Class A, AFFF and AR-AFFF foams and specialized agents for Class D fires.  F-500 EA can do it all!

F-500 Encapsulator Technology vs. AFFF Foams Fire Classifications

Class A Fires
• Flammable solids
• Wood, cloth, rubber
F-500 EA reduces the surface tension of the water allowing for deep penetration into the pores of the fuel. F-500 EA’s rapid cooling results in fast knockdown and excellent burnback resistance. Not applicable; must use a Class A foam for Class A fires.
Class B Fires - Nonpolar
• Flammable liquids
• Gasoline, jet fuel, heating oil
F-500 EA forms micelles around the hydrocarbon liquid and vapor molecules rendering them nonflammable. F-500 EA encapsulates, then cools the fuel so it cannot reignite. AFFF (foam) must separate the fuel from the oxygen. For Class B fuel spills, NFPA 11-Table states foam must be applied for a minimum of 15 minutes at 0.10 gpm/ 2 ft . The amount of foam and water required far exceeds the F-500 EA and water used for a comparable fire.
Class B Fires - Polar
• Flammable liquids
• Ethanol-blended fuels (E10, E85), ethanol, acetone, butanol
F-500 EA can encapsulate both ethanol and ethanol-blended fuels rendering them nonflammable and nonignitable. Ethanol will break down the AFFF (foam) because it is water-based. An expensive AR-AFFF foam must be used in these circumstances. Even then, it must form a blanket and smother the fire.
Class C Fires
• Class A or B, plus electrically energized objects
• High-voltage transformers
• High-voltage car batteries
F-500 EA is not recommended for general Class C fires, however, F-500 EA was the only agent tested by ConEdison at 345 kV with negligible electrical feedback to the nozzle. Transformer fires should be attacked after they are de-energized, but there is no need to be concerned about peripheral equipment that could still be energized. Bosch of Germany tested various agents for high-voltage battery fires and only recommends F-500 EA. Dekra, Daimler and Deutsche ACCUmotive also tested agents on lithium-ion battery fires and concluded F-500 EA was the recommended agent to extinguish hybrid and electric vehicle fires. AFFF (foam) is highly conductive. Transformers are a three-dimensional, hot oil fire with large amounts of hot metal, making AFFF foam ineffective. AFFF (foam) has also been proven to be ineffective on high-voltage, lithium-ion battery fires.
Class D Fires
• Combustible metals
• Magnesium, titanium, sodium
Applying foam to combustible metals creates an explosive situation since the foam is applied with water which releases hydrogen and oxygen. F-500 EA molecules are hydrophylic and attach themselves to water droplets. This prevents the droplets from evaporating and reduces the heat rapidly. With F-500 EA there is no violent reaction from the molten metal. AFFF foam is not to be used on Class D fires and will create an explosive situation.
