F-500 Encapsulator Agent (EA)

Why F-500 EA is Economical


F-500 Encapsulator Agent can be used on most fires.  There is no need to carry Class A foam for Class A fires, AFFF foam for Class B nonpolar fires, AR-AFFF foam for Class B polar fires and powder for Class D combustible metal fires, when F-500 EA can handle all of these fires.  F-500 EA is also approved for ISO (Insurance Services Office) Equivalency List Credit Recognition, so there’s no reason to inventory foam at the station.  F-500 EA has been tested and recommended for transformer fires, and tested by multiple companies for lithium-ion battery fires, particularly hybrid and electric car fires.

Type of Fire

Fire Suppression Agent Required

Class A – wood, paper, tires

F-500 Encapsulator Agent

Class A foam
Class B – nonpolar (gasoline, diesel fuel) AFFF foam
Class B – polar (ethanol, E10, E85) AR-AFFF foam
Class D – Combustible metals Powder; CO2; not foam
All Three-Dimensional Fires


Less Agent Used

Time after time, tests and real life events have shown the superior knockdown capability and burnback resistance of F-500 EA.  The fire is rapidly cooled and the fuel and free radicals are encapsulated, extinguishing the fire.  F-500 EA is competitively priced with foams, so the comparison is simple.  The faster the fire is out, the less agent will be used.

A striking example is a small fuel spill on a highway.  Eight gallons of gasoline would require one gallon of F-500 EA and 40 gallons of water to render it nonflammable and nonignitable.  NFPA 11 (Table states foam must be applied to a nondiked hydrocarbon spill for a minimum of 15 minutes at an application rate of 0.10 gpm/ft2 or 3%.  To safely blanket the ethanol-blended fuel spill, according to NFPA, 36 gallons of AR-AFFF foam will be required with 1,200 gallons of water!  The difference in the cost of F-500 EA vs. the foam is staggering.

Clean-up with F-500 EA is minimal.  Generally, the F-500 EA is left to evaporate.

Less Water Used

More and more communities are taking water usage more seriously.  Water is becoming an expense that needs to be addressed.  In the example above, 40 gallons of water was used with the F-500 EA and 1,200 gallons of water with foam, but the quantity used on the scene is not the whole story.

In many areas, water is not available, such as highways, industrial properties and rural areas.  That means the first fire truck on the scene needs to be carrying enough water to fight the fire or an addition team or tank truck needs to be called in.  An expensive and time consuming drafting operation may be initiated to draw water from a nearby pond. All of this may be unnecessary if F-500 EA is used due to the speed of extinguishment.

Finally, using less water means less water damage at the scene of the fire and probably no runoff into the sewer system or worse, local streams.  Rarely, would a diking operation be required.


Time at a scene is critical.  If the firefighters are paid per call, it makes sense to finish the job quickly.  Even if they aren’t paid per call, delays on scene prevent firefighters from being available for other calls.  Time wasted on overhauls and rekindle callbacks waste time and money.  More time at the scene results in fatigue, which leads to injuries.

Reduced Workman’s Compensation Claims

F-500 EA doesn’t create a scalding steam like water.  Only F-500 EA creates a warm vapor which means firemen won’t be submitting claims for steam burns.  Less time at the scene of a fire reduces injuries associated with fatigue, such as tripping. F-500 EA’s ability to interrupt the free radical chain reaction reduces smoke and toxins, improving visibility.

Using F-500 EA will save your department money.

  • Less agent is needed
  • Less water is used
  • Less time at the scene
  • Fewer workman’s comp claims
