FIREBULL® AB is a PFAS-free fire suppression solution designed to outperform traditional expanded foams while ensuring environmental safety and compliance with new regulations.
For decades, aqueous film-forming foam (AFFF) has been considered the gold standard for suppressing flammable liquid fires. The ability to quickly create vapor retardant films has made them synonymous with reliable Class B protection. However, fluorosurfactants in AFFF, particularly PFAS compounds, pose an environmental and regulatory crisis. Fire departments, industrial facilities, airports, and military organizations around the world are looking for high-performance, fluorine-free alternatives that not only match, but exceed the operational capabilities of traditional foams.
One of the most advanced and proven solutions to emerge during this transition is FIREBULL® AB, a fluorine-free, PFAS-free firefighting concentrate designed to outperform traditional foams while eliminating environmental toxicity. Backed by third-party certifications, global testing standards, and field-proven performance, FIREBULL AB is quickly becoming the preferred alternative to AFFF across the public and private sectors.
New standards for environmental safety: Fluorine-free, PFAS-free
New federal regulations, state-level bans, and international environmental protections are increasing the use of firefighting foams containing PFAS worldwide. FIREBULL AB was designed from the ground up to meet this moment. Free from fluorosurfactants, persistent chemicals, and hazardous ingredients, departments can comply with PFAS regulations without sacrificing operational capabilities.
This formulation was developed in line with a rigorous sustainability framework, including GreenScreen® certification, a respected hazard assessment method used to evaluate chemical ingredients. This certification highlights FIREBULL AB’s commitment to human health, ecological safety and responsible chemistry, providing end users with confidence that their foam selection supports long-term environmental stewardship.
While many fluorine-free foams rely on complex polymer systems, which can themselves pose environmental burdens and operational issues, FIREBULL AB maintains an extremely clean profile. It has a neutral pH, 4 cPs viscosity, and contains no corrosive or hazardous substances, making it one of the most equipment-friendly firefighting foams available today.
Certified across major fire safety standards
A foam’s superior performance is determined by its performance under the world’s most demanding testing protocols. FIREBULL AB has been validated against multiple internationally recognized standards and has proven effective in fighting both Class A and Class B fires.
UL NFPA 18 Wetting Agent Classification
In the NFPA 18 UL test for wetting agents, FIREBULL AB was rated:
0.25% for Class A fires 0.25% to 3% for Class B fires
This broad classification allows for significant operational flexibility. At lower percentages, FIREBULL AB increases the ability of water to penetrate deeply located Class A fuels (such as structural materials, wildland fuels, vehicle interiors, etc.) by improving saturation and heat absorption. Higher percentages provide strong Class B performance against hydrocarbons and non-polar solvents.
These ratings ensure that FIREBULL AB can act as a true multi-class agent, allowing departments to simplify logistics, reduce inventory and rely on a single product for almost all fire types.
EN 1568:1–3 Low, Medium and High Enhanced Performance
FIREBULL AB has been tested according to the European EN 1568 standard for low, medium and high expansion foams over parts 1 to 3. This classification is particularly important for international industrial facilities, airports and petrochemical operators who need to comply with EN-based requirements.
The main benefits are:
Compatible with freshwater or saltwater, eliminating worries when working onshore, offshore, or at sea. Effective across multiple expansion rates, enabling use in structural systems, portable foam generators, high expansion applications, and CAFS. It has high burnback resistance and can form stable blankets without forming a fluorine film.
This versatility is critical for mixed-hazard facilities and institutions seeking a versatile foam concentrate for all expanded applications.
NTA 8133:2021 Lithium battery fire standard
Lithium-ion technology represents one of the fastest growing fire problems across industries from energy storage to transportation to recycling operations. FIREBULL AB meets NTA 8133:2021 standards for lithium battery accidents and has been validated for its ability to cool battery cells, absorb heat, reduce propagation, and assist in vapor mitigation.
Few agencies have this classification, and FIREBULL AB is at the forefront of lithium battery readiness, a growing concern for city authorities and industrial risk managers alike.
Designed for simplicity: instant mixing, neutral pH, minimal maintenance
Many foam concentrates, especially fluorine-free formulations, have high viscosities, slow mixing, or special handling requirements. FIREBULL AB was specifically developed to avoid these problems.
Instant water compatible
With a viscosity of 4 cP, FIREBULL AB is nearly as thin as water and can:
Mixes instantly with eductors, proportioners, and CAFS Free-flowing even in cold weather Works with all standard foam firefighting equipment
This ensures accurate proportions and eliminates the need for specialized pumps or high-energy mixing equipment.
Neutral pH and non-corrosive composition
FIREBULL AB does not contain corrosive components and is therefore extremely gentle on equipment. The advantages are:
Reduced wear on valves, pumps, seals and proportioning systems No residue or corrosive by-products produced Reduced long-term maintenance and repair costs
Departments that switch from AFFF often find that pump seal and eductor reliability increases immediately when using FIREBULL AB.
Unparalleled stability and shelf life
Unlike many foams that deteriorate over time, FIREBULL AB:
No dehydration No condensation No separation
This unique stability allows Enforcer One to offer an unlimited warranty on its concentrates. This is an almost unprecedented initiative in the fire service. Distributors can store FIREBULL AB under normal conditions without worrying about deterioration, solidification, or periodic remixing.
Enforcer® CAFS + FIREBULL AB: Rapid response fire suppression system
FIREBULL AB is fully compatible with standard fire suppression equipment, but its performance increases dramatically when combined with Enforcer Compressed Air Foam Systems (CAFS). These systems are designed to provide a high-energy, highly stable foam flow with increased surface area and deep penetration properties.
40%+ performance improvement
When FIREBULL AB is run on Enforcer CAFS, field tests consistently show over 40% improvement in suppression performance compared to straight water or standard foam systems. This improvement is achieved by:
Better heat absorption due to smaller, more uniform bubbles Better adhesion allows the bubbles to adhere to vertical and overhead surfaces Longer residence time and extended vapor suppression Deeper penetration into fires for Class A materials Enhanced suffocation effect on Class B surfaces
This combination significantly reduces extinguishing time, water consumption and property damage.
Rapid response packages for industry and fire departments
By combining Enforcer CAFS and FIREBULL AB, departments and industrial brigades can benefit from:
Lightweight, portable rapid attack unit Truck-mounted CAFS system for structural, vehicle, and industrial incidents Improved wildland and urban interface capabilities Highly effective suppression for fuel spills, battery fires, recycling facilities, transfer stations, and EV incidents
This integrated system is currently used across industries including transportation hubs, manufacturing plants, energy facilities, waste management operations, and municipal fire services.
Nationwide Solution: Perma-Fix and Enforcer One Partner
In a recent announcement that signals a major shift in firefighter safety and environmental responsibility, Perma-Fix Environmental Services and Enforcer One have teamed up to streamline the nationwide removal, destruction, and replacement of PFAS-based AFFF.
This partnership provides government agencies and industrial facilities with:
