Lithium Battery (Lith-Ex) Fire Extinguishers
The following fire extinguishers are specifically designed for use on lithium-ion battery fires which are technically a Class A fire risk but with some important differences (explained below).
The dangers of lithium-ion battery fires are with the electrolyte solution in the batteries rather than the lithium salts they contain. Each battery utilises a different electrolyte solution but many contain Fluoride which actively combines with the hydrogen in water used for fire fighting to make Hydrogen Fluoride.
This is a highly toxic gas which can cause respiratory failure and blindness, in liquid form (Hydrofluoric Acid) it is highly corrosive and is absorbed through the skin. So even though lithium-ion batteries are theoretically a Class A fire risk and can be extinguished with water, this could lead to potentially dangerous or deadly side effects.
