Firechief Lith-Ex Fire Extinguishers contain Aqueous Vermiculite Dispersion (AVD), a revolutionary fire extinguishing agent designed to put out Lithium-ion battery fires fast.

The water content of the extinguisher cools the fire source, while the Vermiculite platelets encapsulate the fuel source creating a thermal barrier to prevent the propagation of the fire. The Vermiculite film is not electrically conductive so AVD is nearly twice as effective as water on Class A fires and is environmentally friendly.

Lithium-ion batteries present a more frequent fire hazard each day as the number of consumer and industrial goods powered by them increases. Firechief Lith-Ex Fire Extinguishers are suited to confined spaces where fires need to be suppressed in their infancy before developing into a fully established fire. They can also be used to protect against fires where batteries are under charge and where batteries are stored, for example, goods distribution, battery collection bins, battery recycling locations, public services, and battery charging stations.
