6 Litre Fluorine-Free Foam Lithium-Ion Battery Fire Extinguisher (FEL6L)

Engineered with Advanced F3 Technology to Defeat Thermal Runaway and Secure High-Risk Australian Environments

The proliferation of lithium-ion (Li-ion) battery technology across every sector of the Australian economy has introduced a new and volatile fire risk. Fire and Rescue NSW (FRNSW) has identified Li-ion batteries as the fastest-growing fire risk in the state, a trend reflected nationwide. In response to this critical safety challenge, the 6 Litre Fluorine-Free Foam Lithium-Ion Battery Fire Extinguisher (FEL6L) has been engineered as a purpose-built, next-generation solution.

The Dynamics of Thermal Runaway
A lithium-ion battery fire is not a typical combustion event; it is a violent, cascading chemical reaction known as thermal runaway. This process is initiated when a battery cell is damaged through overcharging, physical impact, penetration, manufacturing defects, or exposure to extreme heat. Once a single cell is compromised, it enters an uncontrollable, self-heating state that rapidly escalates, presenting a unique and formidable set of hazards

The FEL6L Mechanism: A Multi-Faceted Attack on the Fire Tetrahedron
Advanced Fluorine-Free (F3) Foam Formulation
The extinguishing agent in the FEL6L 6L Lithium-Ion Battery Fire Extinguisher is a state-of-the-art, water-based formulation discharged in a foam-like manner. It is an aqueous solution composed of carefully selected hydrocarbon surfactants, foam stabilisers, and proprietary additives designed to deliver superior performance against both conventional fires and the unique challenges of thermal runaway. Critically, the agent is completely free of any fluorinated compounds (PFAS), ensuring it meets modern environmental and health standards.

Certified Performance and Uncompromising Australian Compliance
Versatile Fire Ratings (AS/NZS 1850)
The FEL6L is engineered to be a versatile fire protection asset, not a niche, single-use device. It has been rigorously tested and certified in accordance with Australian Standard AS/NZS 1850, achieving a fire rating of 4A:5B:4F. This powerful rating confirms its effectiveness against:

Class A Fires: Carbonaceous solids such as wood, paper, plastics, and textiles.

Class B Fires: Flammable and combustible liquids like petrol, diesel, oils, and solvents.

Class F Fires: Fires involving cooking oils and fats.

This versatile rating ensures the extinguisher provides excellent protection against the most common fire risks found in commercial and industrial settings, making it a suitable and compliant choice for installation under AS 2444.

Proven Efficacy on Lithium-Ion Batteries

While Australian Standards do not currently feature a specific classification for lithium-ion battery fires, the Lithium Ion Battery Fire Extinguisher FEL6L's performance against this hazard has been validated through extensive independent testing. The formulation has been proven effective in extinguishing fires in lithium-ion battery packs with an energy capacity of up to 600Wh.

This provides tangible, verifiable performance data that demonstrates its capability to handle fires in a wide range of devices. Its performance is further substantiated by successful independent testing by Kiwa in the Netherlands against the international protocol NTA 8133:2021, a recognised standard for lithium-ion battery fire safety.
