Ansul Lith-X Class D Extinguisher Powder, 45 lb pail

Ansul Lith-X Class D extinguishing agent was developed for use on lithium fires and will also extinguish magnesium, sodium, and potassium fires. It will contain, and in some cases completely extinguish, fires of zirconium, titanium, and sodium-potassium alloy. Lith-X is our most popular Class D agent and is a preferred choice of battery researchers and manufacturers who utilize metallic lithium. This agent is suitable for lithium metal batteries (disposable, single use batteries only). For protection for lithium ion (rechargeable) batteries commonly found in laptops, phones and power tools see the Technical Note below.

For small quantities, many people apply this agent with a scoop or shovel, but for larger quantities we suggest an actual extinguisher to give you stand-off fire fighting ability; see below for details.  The 45 lb pail is Ansul part number 9334.

Lith-X has a special graphite base with additives to render it free-flowing so that it may be used in extinguishers. It does not cake or crust like sodium chloride-based agents, but will exclude air and conduct heat away from the burning mass to extinguish the fire.

Technical note: Rechargeable lithium ion batteries do not pose a Class D fire threat but typically involve a flammable electrolyte material or casing and should be protected by an appropriate Class ABC or BC dry chemical extinguisher.  ABC would be your first choice unless you had other considerations - for example, aircraft or electronic equipment would dictate a Class BC dry chemical or clean agent such as CleanGuard, Halotron, carbon dioxide or water. For a technical report that discusses suppression of lithium ion battery fires see the suppression discussion of Lithium Ion Batteries Hazard and Use Assessment at the NFPA. Lithium metal batteries (which are single use) do pose a Class D threat.
