[vc_row][vc_column][vc_column_text]Aqueous Vermiculite Dispersion (AVD)<\/strong> fire extinguishing agent is a new, revolutionary technology that uses fixed and portable delivery techniques to effectively combat lithium-ion battery fires.<\/strong><\/p>\n

Lithium battery failure<\/strong> can be caused by the following:
\nPhysical impact or penetration, Overheating, Short circuits, Internal cell failure, Manufacturing defects.<\/p>\n

With the rise in technology that uses lithium batteries, comes the added risk of lithium battery fires<\/strong>. How prepared are you for a lithium battery fire? And are lithium batteries dangerous?<\/p>\n

The consequences of lithium battery fires are severe, so having the right precautions in place is critical.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=”.vc_custom_1648391283406{background-color: #dd3333 !important;}”]<\/p>\n

[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]What is AVD made of?<\/strong>
\nAVD is an aqueous dispersion of chemically exfoliated vermiculite. It is applied to lithium battery fires as a mist, extinguishing them and preventing the propagation of the fire.<\/p>\n

Vermiculite is the name given to a group of hydrated laminar aluminium-iron-magnesium silicates. It consists of thin, flat flakes containing microscopic layers of water. The chemical exfoliation of vermiculite produces microscopic, individual platelets that are freely suspended in water. This yields a stable aqueous dispersion of vermiculite to be used as a lithium battery fire extinguishing agent.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_separator color=”green”][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]Is AVD environmentally safe?<\/strong>
\nVermiculite is a naturally occurring mineral that is exempt from REACH regulations. It is chemically and physically inert, only releasing steam when exposed to raised temperatures. It is also non-toxic to humans, plant life and animals.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_separator color=”green”][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]How does AVD work?<\/strong>
\nThe vermiculite particles within the mist are deposited on the surface of the burning fuel to create a film over the top of the fire. The film instantly dries and, because the high aspect ratio platelet particles overlap and bind together, a non-flammable oxygen barrier between the fuel and the atmosphere is produced.<\/p>\n

This process has a cooling effect on the fuel source and, as the water content in AVD is evaporated, the vermiculite platelets begin to build up and the fire is brought under control.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/2″][vc_column_text]<\/p>\n
