Firechief 500ml Lith-Ex Fire Extinguisher (FLE500)

The world's first Fire Extinguisher to tackle Lithium ion battery fires such as mobile phones, tablets, laptops, toys, power tools and electric scooters.

Lith-Ex Fire Extinguishers cover the following types of fires:

Why do you need it?

By simply dropping or crushing your mobile phone it can cause it to catch fire. Do you leave your phone on charge overnight? Overcharging and charging malfunctions can cause your mobile phone to catch fire! Lithium Battery Fires can quickly exceed temperatures of 800°C - three times hotter than an oven!

AVD Compound Technology

When a battery is in thermal runaway (a condition where the increasing heat of the battery causes a reaction which further increases the heat and continues this heat generating process until all of the stored energy is exhausted), the temperature can rise again after being cooled leading to re-ignition. In this situation an agent which can overpower this reaction without limitations is necessary.

AVD (Aqueous Vermiculite Dispersion) is a stable dispersion of refractory vermiculite platelets in water. When applied to the initial fire, AVD quickly extinguishes it; the water cools the system, the high surface area mineral platelets interrupt the radical chain reaction and a refractory film forms which impedes oxygen diffusion to the fuel source.

Another advantage of AVD is that as it dries it forms a thermally insulating film which reduces the risk of thermal runaway propagation to adjacent cells. The non-combustible vermiculite film also coats the packaging of adjacent cells preventing the spread of fire. The film also isolates combustible components from the air, preventing ignition.
