HMS® (Hydrated Mica Suspension)

India's Advanced Mineral-Based Fire Suppression Technology for Lithium-Ion Battery Fire Protection

HMS® Hydrated Mica Suspension | Lithium Battery Fire Solution

Engineered for the Fire Risks of Tomorrow

The rapid adoption of Electric Vehicles (EVs), Battery Energy Storage Systems (BESS), renewable energy projects, data centres, UPS installations, telecommunications, and lithium-ion powered equipment has transformed the global energy landscape. While these technologies deliver remarkable efficiency and sustainability, they also introduce a new generation of fire hazards that differ significantly from conventional combustible fires.

Lithium-ion battery fires present unique challenges due to their high energy density, the possibility of thermal runaway, rapid heat generation, flammable gas release, and the potential for re-ignition. These characteristics demand fire protection solutions specifically engineered for battery-related incidents.

To address this evolving challenge, LIFEGUARD has developed HMS® (Hydrated Mica Suspension)—an advanced, mineral-based fire suppression agent designed for use in products and systems intended for lithium-ion battery fire protection.

What is HMS® (Hydrated Mica Suspension)?

HMS® (Hydrated Mica Suspension) is a proprietary extinguishing medium developed by LIFEGUARD using specially processed hydrated mica dispersed in a water-based suspension. The formulation is intended for application in fire extinguishers and engineered suppression systems designed for lithium-ion battery hazards.

The suspension combines the cooling capability of water with the surface coverage characteristics of hydrated mica, making it suitable for applications where prolonged cooling and coverage are important considerations.

Developed through extensive research and product engineering, HMS® represents LIFEGUARD's commitment to advancing indigenous fire protection technologies for emerging energy systems.

Designed for Lithium-Ion Battery Fire Protection

Unlike conventional fires involving paper, wood, or hydrocarbon fuels, lithium-ion battery incidents may involve:

• Cell thermal runaway
• High heat generation
• Rapid propagation between adjacent cells
• Release of combustible and toxic gases
• Potential re-ignition after initial flame suppression

HMS® is intended for use in systems engineered to support cooling and suppression strategies for such applications, alongside appropriate detection, battery management, and emergency response measures.

How HMS® Works

The performance of HMS® is based on the characteristics of its mineral-water suspension.

Efficient Cooling

The water component helps absorb heat from the affected area, supporting temperature reduction around battery modules and surrounding equipment.

Surface Coverage

Hydrated mica particles remain suspended within the extinguishing medium and are designed to coat exposed surfaces during discharge, contributing to continued coverage after application.

Fire Suppression Support

When discharged through appropriately designed extinguishers or fixed suppression systems, HMS® assists in controlling visible fire development within the protected area.

Re-Ignition Risk Reduction

By combining cooling with surface coverage, HMS® is intended to support strategies aimed at reducing the likelihood of renewed flaming, recognizing that lithium-ion battery incidents vary depending on battery chemistry, state of charge, and system design.
