Containing the Uncontrollable: Advancing Military Fire Protection with DynaGuard® EVB Fire Blankets

From hybrid tactical vehicles and unmanned systems to portable microgrids and aerospace platforms, lithium-based energy systems are now central to operational capability. These technologies introduce fire hazards that behave very differently from traditional fuel-based threats resisting conventional suppression methods.

To address this challenge, ThermoDyne’s DynaGuard® EVB Fire Blanket delivers a critical advancement: a rapid-deployment thermal containment system that isolates fire and enables active cooling through the blanket itself.

A Changing Risk Environment

Modern military operations increasingly rely on electrified systems to enhance mobility, reduce signatures, and support distributed energy strategies. These systems introduce:

• Rapid thermal runaway events
• Extreme heat output beyond conventional suppression
• Toxic and flammable gas release
• High risk of fire propagation in tightly staged environments

These risks are amplified in forward operating bases, shipboard compartments, maintenance depots, and flight lines, where space is limited and assets are concentrated.

Traditional firefighting methods—water, foam, or chemical agents—often struggle to fully control lithium-ion battery fires, particularly without direct access to the heat source.

Beyond Containment: Cooling Through the Blanket

The DynaGuard® EVB Fire Blanket is engineered to go beyond traditional fire blankets by incorporating a water-permeable design. This allows responders to apply water directly through the blanket while it remains in place over the fire.

This creates a controlled, two-phase response:

Immediate Containment

• Blanket is deployed over the affected vehicle or equipment
• Flames, heat, and gases are contained at the source
• Fire spread to adjacent assets is prevented

Active Cooling

• Water is applied through the blanket—not around it
• Cooling reaches the battery cells driving thermal runaway
• Continuous application reduces the risk of reignition

Critically, the blanket remains in place throughout the process, maintaining containment while enabling suppression.
This aligns with real-world operational guidance:

Deploy → Cover Completely → Do Not Remove → Apply Water Through Blanket → Continue Cooling

Operational Advantage in Military Environments

This combined containment-and-cooling capability is particularly valuable in military settings where:

• Personnel exposure must be minimized
• Fires occur in tight or confined environments
• Access to the source of the fire is limited or hazardous

By allowing water application without removing the blanket, operators can:

• Maintain full thermal containment
• Deliver cooling directly to the hazard

The result is a safer, more controlled firefighting approach that supports both mission continuity and personnel protection.

Multi-Domain Applications

Electrified Ground Vehicles

As hybrid and electric tactical vehicles enter service, the risk of battery-related fires increases across motor pools and forward operations.

Advantage: Rapid containment prevents fire spread, while water application through the blanket cools the battery without exposing the hazard.

Maintenance Depots & Forward Operating Bases

Battery charging stations and repair facilities concentrate high-energy systems in confined spaces.

Advantage: Enables immediate containment and controlled cooling, reducing damage to infrastructure and adjacent equipment.

Aerospace & UAV Operations

Unmanned systems and electrified ground equipment rely heavily on lithium-ion batteries, particularly during charging.

Advantage: Provides a fast-response solution that allows continued cooling without disrupting surrounding operations.

Naval & Shipboard Environments

Fire control at sea requires precise management in confined, high-risk spaces.

Advantage: Blanket contains fire and smoke while allowing water to be applied through the blanket, directly to the source minimizing contamination.

Expeditionary Energy Systems

Portable energy storage systems are critical to modern deployments but introduce significant fire risk.

Advantage: Prevents cascading failures while enabling sustained cooling in remote or resource-constrained environments.

Engineered for Defense Performance

Drawing on ThermoDyne’s expertise in advanced thermal management systems, the DynaGuard® EVB Fire Blanket is designed for demanding operational conditions:

• High-temperature resistant materials for extreme events
• Water-permeable construction for active suppression
• Durable, reusable design for repeated deployment
• Lightweight and portable configuration for rapid response

This ensures the system integrates seamlessly into existing safety protocols while addressing the unique challenges of lithium-based energy systems.

A Critical Evolution in Fire Response

Modern military fire protection must go beyond suppression alone. It must:

• Contain the hazard
• Control escalation
• Enable effective cooling at the source

The DynaGuard® EVB Fire Blanket achieves all three—providing a practical, field-ready solution for one of the most dangerous emerging threats in modern operations.

As electrification reshapes the battlespace, so too must the strategies used to manage risk.

By combining thermal containment with water-permeable cooling capability, the DynaGuard® EVB Fire Blanket delivers a new standard in fire response—one that enhances safety, survivability, and operational readiness across all domains.

Contain the fire. Cool the source. Maintain control.
