Fire Cloak™ - Lithium Battery Fire Limitation Blanket - (13' x 10')            

This lithium battery fire blanket is built from an ultra-high–silica fabric and coated on both sides with a durable, fire-resistant grey silicone layer. Reinforced corner sections include heavy-duty silicone-fabric pull handles for safe positioning, and all seams are stitched with high-temperature-resistant thread to maintain strength during emergency use.

Fire Classification Insight

While formal BS EN 13501-1:2018 testing is pending, manufacturer analysis indicates that the LBB6143 blanket material is expected to reach an A1 Reaction to Fire rating.

Status as of January 2024.

Purpose & Use Case

This blanket is engineered to contain and manage lithium-ion battery fires, one of the most hazardous types of incidents due to the self-sustaining reaction known as thermal runaway. In these scenarios, a failed cell overheats, ignites, and spreads heat to neighboring cells—often exceeding 1,000°C and resisting standard extinguishing methods because the battery generates its own fuel and oxygen.

Why This Blanket Is Effective

Deploying a lithium battery fire blanket helps to:

• Restrict oxygen supply to the burning cells

• Limit flame spread and combustion

• Lower peak temperatures more quickly

• Provide protection to surrounding assets and personnel

• Stabilize the scene while awaiting specialized cooling or suppression measures

Deployment

Two trained operators can set the blanket in place quickly, and it is supplied in a rugged storage holdall for straightforward transport, staging, and long-term storage.
