Extover® — Canadian-Made Lithium-Battery Fire Protection

Made in Canada. Faster Canadian shipping. Reliable domestic supply without cross-border delays.

Extover® is an environmentally friendly extinguishing and containment agent developed for lithium-ion battery incidents and Class D fires.

Made from post-consumer recycled pure glass, each bag provides a lightweight, free-flowing material that can help control fire, absorb thermal energy and electrolyte, and reduce the risk of re-ignition.

How Extover® Works

• Smothers: Covers the affected battery and limits its exposure to oxygen
• Cools: Absorbs thermal energy and helps contain the spread of heat
• Seals: Forms a protective barrier that helps prevent re-flaming
• Absorbs: Takes up leaked electrolyte and other fluids
• Contains: Captures vapours and fumes on the granule surface for controlled disposal

Fire Department Starter Recommendation

Extover® is sold by the bag, allowing departments and facilities to purchase the quantity appropriate for their needs.

For initial readiness, CESAT recommends that every fire department maintain a minimum three-bag supply for small damaged, defective or recalled lithium-battery incidents.

Larger batteries, multiple batteries and more serious thermal-runaway events may require substantially more material and additional emergency-response measures.

Order one bag or select the 3-Bag Starter Kit for minimum fire-department readiness.

Shipping and taxes are extra. Shipping is available across Canada. No customs or duties required.
