Featuring the advanced Aqueous Vermiculite Dispersion (AVD) agent, this extinguisher provides rapid and effective fire control, making it an essential safety measure for industrial sites, battery storage facilities, and high-risk work environments. 

Designed for large fires, the Firechief 50L Lith-Ex extinguisher delivers high-performance firefighting capabilities with an easy-to-use trolley system for swift action. Fully CE marked and MED approved, it upholds the highest safety and quality standards for reliable use every time. 

The AVD mist quickly suppresses lithium-ion battery fires by cooling the affected area and disrupting the thermal runaway process. This prevents fire spread and minimises the risk of re-ignition. When deployed, AVD creates a durable vermiculite film that encapsulates the burning material, preventing oxygen exposure and further combustion. As a non-toxic and eco-friendly agent, AVD offers a safe and sustainable approach to lithium-ion battery fire suppression. 


What is AVD?

Aqueous Vermiculite Dispersion (AVD) is a next-generation extinguishing agent specifically for lithium-ion battery fires. Comprising 17% vermiculite and 83% water, AVD has a thick, cream-like viscosity (3000 cPs) that delivers unmatched fire suppression performance.

Benefits of AVD:

  • Rapid Cooling - The water component instantly reduces heat, stopping the spread of thermal runaway
  • Protective Encapsulation - The vermiculite forms a barrier over the burning battery, preventing oxygen and heat from fueling the fire further.
  • Non-Conductive Properties - The vermiculite layer is electrically insulating, making it safe for use in fires involving live electrical components.


With nearly double the efficiency of water-based suppression methods, AVD offers a reliable and advanced approach to lithium-ion battery fire mitigation. 


The Dangers of Lithium-Ion Battery Fires

Lithium-ion batteries are crucial to modern energy storage, yet they pose a significant fire risk when mishandled, overcharged, or physically damaged. These batteries can enter thermal runaway, a self-sustaining reaction that releases heat, flammable gases, and hazardous smoke. If not properly managed, lithium-ion battery fires can spread rapidly and reignite even after initial suppression. 

Unlike traditional fire extinguishers, lithium-ion battery fire extinguishers are designed to address these risks, ensuring complete fire control and preventing reignition. Its large capacity and advanced agent technology make it an ideal choice for protecting high-risk areas where lithium-ion batteries are stored and used.
