Product Description

A potent solution that swiftly cools down overheated batteries, stops thermal runaway within seconds, and forms a protective barrier between cells to halt the spread of fire. Fireblock Lithium is essential for managing lithium battery fires effectively.

Lithium batteries are commonly used in our daily electronics like phones and laptops, as well as in larger setups like solar and backup power installations. However, if these batteries are mishandled, overcharged, or overheated due to incorrect installation and use, they can catch fire.

Such fires are usually accompanied by thermal runaway within cells and thermal propagation between cells. To have any chance of stopping both thermal runaway and preventing thermal propagation, high-performance properties are required of a fire extinguishing agent.

To prevent or even arrest thermal runaway requires significant cooling action to interrupt the unstable chemical process, and to prevent thermal propagation we must provide a thermal insulation or ‘Fireblock’ between cells.

Lithium fires are extremely difficult to fight due to the chemical nature of the different batteries. Once they have caught alight the temperate rises rapidly and thermal runaway occurs. In addition to the release of flammable materials, is the associated risk of toxic smoke, which increases the hazard of the fire.

FIREBLOCK LITHIUM Gel has both properties in abundance, with the capability to stop thermal runaway and prevent thermal propagation.

Key Features:

• Specialised Extinguisher: Fireblock Lithium is a gel designed specifically to tackle lithium battery fires that other extinguishers can’t handle.
• Eco-Friendly: It’s non-toxic and completely biodegradable, making it safe for both people and the environment.
• Effective Cooling: Its unique formula swiftly knocks down flames and cools down the fire, thanks to its powerful composition.
• Surface Adherence: Fireblock Lithium sticks to surfaces well, minimising run-off and ensuring efficient firefighting.
• Temperature Reduction: It significantly lowers the temperature of the battery pack, preventing further escalation of the fire.
• Quick Action: Tests have proven that Fireblock Lithium rapidly reduces battery temperature in under a minute, curbing thermal runaway.
• Prevents Spread: Acting as a barrier between cells, it stops fire propagation within battery packs, enhancing safety.
• Minimal Run-off: With less than 10% runoff, it minimises environmental contamination from lithium chemicals.
• Smoke Reduction: By substantially reducing toxic smoke, Fireblock Lithium mitigates environmental impact and lowers explosion risks in confined spaces.

It’s important to note that when dealing with lithium battery fires, safety precautions should be taken, and the use of the appropriate fire extinguishing equipment, like a lithium battery fire extinguisher, is essential to minimise the risk of injury or property damage.

Fireblock Lithium fire extinguishers hold the following international accreditations: UKCA 0086, CE 2797, BSI Kitemark KM57904.

Fireblock is an insurance-compliant and BSI Kitemark-accredited lithium battery fire extinguisher. Fireblock Lithium must be serviced annually by a BSI or SANS approved company and SAQCC registered technician. Refilling must be done by FIREBLOCK if required.
