GreenFire® FAQ's
AFFF Replacement Foam

What is GreenFire®?

AFFF Replacement Greenfire PFAS Free BadgeGreenFire® is the Fluorine Free, PFAS Free AFFF Replacement Foam.  Food Safe, Non-Toxic and Non Carcinogenic.


GreenFire® belongs to a unique class of fluids called non-Newtonian fluids. These fluids can change viscosity depending on their circumstances.


In the case of GreenFire it is called a shear-thinning fluid. What this means is that when it is in a high shear environment (such as passing through a hose or a pump) the viscosity drops, nearly to that of plain water. This allows it to flow easily with minimal pressure loss.


After it exits the hose and lands on its target surface the viscosity increases again to become closer to that of maple syrup. This allows for greatly enhanced extinguishing capabilities while minimizing runoff.


The Leidenfrost effect is a phenomenon in which a droplet of water is unable to make physical contact with its target surface due to a steam barrier that forms between them.

The proprietary blend of wetting agents contained in GreenFire allow it to break through this steam barrier and provide immediate cooling to even the hottest surfaces. These properties allow for much faster fire knockdown and use of up to 90% less water.


  • Proprietary mixture/trade secret as defined by 29CFR 1910.1200 Contains natural boron compounds, food grade wetting agents, anionic detergents.
  • Uses 20% LessThe Amount Of Water Required By Other Products. Penetrating The Agent, Allowing It To Last Longer. This Increases The Absorption Of GreenFire® Into Any Fuel, And Prevents Re-Ignition

Can GreenFire® be applied to my home and defensible space to help prevent fires?

Yes. We have our Home Defense blend that you can purchase and apply it yourself. If you need someone to apply it, you can call one of our GreenFire® Dealers. They can help you.

Can GreenFire® be used in a wildfire area?

Yes. In fact, it should be the first choice. Being that it has a Food Safe Label means it is safe for the forest. The USDA governs what Fire Fighting Products are fit for use in fighting wildfires. The reason is that what hits the soil eventually enters our water tables. That starts the snowball affect of ingesting chemicals by humans and animals.
We are Food safe and PFAS Free!

What is AFFF?

AFFF stands for Aqueous film forming foam.  AFFF is a highly efficient type of fire suppressant agent, used by itself to attack flammable liquid pool fires, and in conjunction with Halon 1301 to attack fires in Navy vessel machinery spaces.

However it is highly TOXIC to people

All AFFF products contain PFAS. This applies to foams used in the past and those being sold today. Foam currently in stock or new foam that is labeled as AFFF or AR-AFFFcontains perfluoroalkyl or polyfluoroalkyl substances, or both, as active ingredients

Certain PFAS can accumulate and stay in the human body for long periods of time. Long-term exposure to PFAS/PFOA/PFOS, in high concentrations, causes a buildup in the body. This buildup may have negative health effects like a risk of thyroid disease and testicular, kidney and bladder cancers.

GreenFire is and AFFF Replacement Foam that is completely Safe for humans, animals and the environment.  Contains no PFAS and is Fluorine free.

Does GreenFire contain PFOA, PFOS or any other similar compounds are chemicals?

No. GreenFire® is free from all harmful chemicals. Such as the “forever” chemicals. Does not contain polyfluoroalkyl substances (PFAS) or Perfluorooctanoic acid (PFOA).


GreenFire® is an effective and safe AFFF Replacement Foam

What makes GreenFire truly a green product and can other products make the same claim?

GreenFire® does not contain anything remotely close to being toxic, carbon based, or chemical based. No other product in our industry can say that.

It is the GREEN replacement for AFFF.

Are fire departments and firefighters currently using GreenFire®?


What is fire prevention?

Fire prevention is a function of many fire departments. The goal of fire prevention is to educate the public to take precautions to prevent potentially harmful fires, and be educated about surviving them. It is a proactive method of reducing emergencies and the damage caused by them. Many fire departments have a Fire Prevention Officer.


In the general sense of preventing harmful fires, many aspects are discussed in the articles Fire protection and Fire safety. National work on best practices is in the Vision 2020 program


Fire prevention is also something that is important for home owners.  Find out more about our Home Fire Prevention Program.

What’s fire protection mean? Is it different than prevention?

Fire protection is the study and practice of mitigating the unwanted effects of potentially destructive fires.[1] It involves the study of the behaviour, compartmentalisation, suppression and investigation of fire and its related emergencies, as well as the research and development, production, testing and application of mitigating systems. In structures, be they land-based, offshore or even ships, the owners and operators are responsible to maintain their facilities in accordance with a design-basis that is rooted in laws, including the local building code and fire code, which are enforced by the Authority Having Jurisdiction.

Buildings must be constructed in accordance with the version of the building code that is in effect when an application for a building permit is made. Building inspectors check on compliance of a building under construction with the building code. Once construction is complete, a building must be maintained in accordance with the current fire code, which is enforced by the fire prevention officers of a local fire department. In the event of fire emergencies, Firefighters, fire investigators, and other fire prevention personnel are called to mitigate, investigate and learn from the damage of a fire. Lessons learned from fires are applied to the authoring of both building codes and fire codes.

What is Fire Retardant

fire retardant is a substance that is used to slow down or stop the spread of fire or reduce its intensity. This is commonly accomplished by chemical reactions that reduce the flammability of fuels or delay their combustion.[1][2] Fire retardants may also cool the fuel through physical action or endothermic chemical reactions. Fire retardants are available as powder, to be mixed with water, as fire-fighting foams and fire-retardant gels. Fire retardants are also available as coatings or sprays to be applied to an object.[3]

Fire retardants are commonly used in fire fighting, where they may be applied aerially or from the ground.

What is Fire Suppression?

Fire suppression systems are used to extinguish or prevent the spread of fire in a building. Suppression systems use a combination of dry chemicals and/or wet agents to suppress equipment fires.

In the USA fire suppression systems are governed by the codes under the National Fire Protection Association. Suppression systems have become a necessity to several industries as they help control damage and loss to equipment. Common means of detection are through heat sensors, wiring, or manual detection (depending on system selection).

What are PFAS?

Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that includes PFOA, PFOS, GenX, and many other chemicals. PFAS have been manufactured and used in a variety of industries around the globe, including in the United States since the 1940s. PFOA and PFOS have been the most extensively produced and studied of these chemicals. Both chemicals are very persistent in the environment and in the human body – meaning they don’t break down and they can accumulate over time. There is evidence that exposure to PFAS can lead to adverse human health effects.

PFAS can be found in:

  • Food packaged in PFAS-containing materials, processed with equipment that used PFAS, or grown in PFAS-contaminated soil or water.
  • Commercial household products, including stain- and water-repellent fabrics, nonstick products (e.g., Teflon), polishes, waxes, paints, cleaning products, and fire-fighting foams (a major source of groundwater contamination at airports and military bases where firefighting training occurs).
  • Workplace, including production facilities or industries (e.g., chrome plating, electronics manufacturing or oil recovery) that use PFAS.
  • Drinking water, typically localized and associated with a specific facility (e.g., manufacturer, landfill, wastewater treatment plant, firefighter training facility).
  • Living organisms, including fish, animals and humans, where PFAS have the ability to build up and persist over time.

Certain PFAS chemicals are no longer manufactured in the United States as a result of phase outs including the PFOA Stewardship Program in which eight major chemical manufacturers agreed to eliminate the use of PFOA and PFOA-related chemicals in their products and as emissions from their facilities. Although PFOA and PFOS are no longer manufactured in the United States, they are still produced internationally and can be imported into the United States in consumer goods such as carpet, leather and apparel, textiles, paper and packaging, coatings, rubber and plastics.-EPA

All AFFF firefighting foams contain PFAS.

Does GreenFire perform better Than leading competitors even though it is PFOS Free?

(PFOA FREE) Harmful chemicals can seem to perform, our performance can’t be touched. When it comes to an honestly green product, GreenFire is the only product with a Food Safe label. When the others join us, we can truly compare. Does it do what the others can do? Yes. When performing our certification test, NFPA 18 Wetting Agent, we did so with a blend that was diluted with about 80% water. This was an accident, yet it worked flawlessly! In another Heptane Fuel test, conducted in-house, we put out the fire in less than ten-seconds. That’s huge!

GReenfire is the green replacement for AFFF.

What are the negative impacts of AFFF chemicals?

To name a few:
  • Testicular, kidney, liver and pancreatic cancer.
  • Reproductive problems
  • Weakened childhood immunity
  • Low birth weight
  • Endocrine disruption
  • Increased cholesterol
  • Weight gain in children and dieting adults

Are these dangerous and caustic chemicals (AFFF) required to provide an efficient fire prevention and/or fire extinguishing product?

No. GreenFire has proven this through testing guidelines set out by UL and NFPA.

Does GreenFire® perform better Than leading competitors even though it is PFOS Free?

Our best performance starts with:
  • being a cancer free alternative in the Fire Fighting Product forum.
  • being the first ever Food Safe Fire Fighting Product.
  • the ability to put out a Heptane Fuel fire in less than nine seconds, we had three minutes. See the Video for yourself below.

Is GreenFire® able to be used in Kitchens and food environments?

Indeed! The only Food Safe Fire Fighting Product, Approved by the NSF/USDA for food environments. Not to be confused with Food Grade.
