HMS-BASED CLASS L FIRE PROTECTION
Standards-Aligned Technical Framing
1️⃣ ALIGNMENT WITH IS 2190
(Selection, Installation & Maintenance of Fire Extinguishers – India)
Standards Context
IS 2190 recognizes that fire extinguishers must be selected based on the nature of fire risk and burning characteristics of materials involved, and explicitly discourages misuse of extinguishers outside their intended application.
Standards-Aligned Framing
Lithium-ion battery fires exhibit internal heat generation, sustained combustion, and re-ignition potential, which differ fundamentally from conventional Class A, B, or C fires.
Accordingly:
Fire extinguishing agents for lithium-ion battery installations shall be specifically suitable for high-heat, electrically energized, and re-ignition-prone fire scenarios, in line with the intent of IS 2190 for risk-based extinguisher selection.
HMS Positioning (IS 2190 Safe Language)
- Water-based agent with enhanced heat absorption capability
- Suitable for energized electrical environments
- Designed to address deep-seated heat, not only visible flames
- Supports IS 2190’s principle of correct agent–risk matching
2️⃣ ALIGNMENT WITH AIS & CMVR
(Automotive Industry Standards & Central Motor Vehicle Rules – India)
Standards Context
AIS and CMVR requirements for EVs and electric buses emphasize:
- Passenger safety
- Mitigation of fire propagation
- Early suppression at first availability
- Avoidance of secondary hazards
They acknowledge lithium-ion batteries as a distinct risk in electric mobility platforms.
Standards-Aligned Framing
Lithium-ion battery fires in vehicles involve:
- Rapid temperature escalation
- Confined battery compartments
- Limited manual intervention time
Therefore:
Fire suppression provisions in electric vehicles shall be capable of rapid heat knockdown, containment of battery fire propagation, and minimization of re-ignition risk, consistent with AIS safety intent.
HMS Positioning (AIS / CMVR Compatible)
- Non-explosive, non-pressurized discharge
- Effective in confined battery enclosures
- Supports first-response intervention by drivers or staff
- Minimizes collateral damage to vehicle systems
This aligns with CMVR’s objective of life safety without introducing new operational risks.
3️⃣ ALIGNMENT WITH NFPA 855
(Standard for the Installation of Stationary Energy Storage Systems)
Standards Context
NFPA 855 explicitly recognizes:
- Thermal runaway as the primary hazard
- Re-ignition after initial suppression
- The need for long-duration cooling and monitoring
- Limitations of traditional suppression methods
NFPA 855 does not mandate a single agent, but requires performance-based mitigation of thermal runaway consequences.
Standards-Aligned Framing
For lithium-ion battery installations:
Fire mitigation measures shall address thermal runaway propagation, sustained heat release, and re-ignition prevention, rather than flame knockdown alone.
HMS Positioning (NFPA 855 Language Safe)
- Designed to absorb and dissipate battery heat
- Helps limit cell-to-cell propagation
- Supports extended cooling objectives
- Complements detection, isolation, and emergency response strategies prescribed in NFPA 855
4️⃣ CONSOLIDATED COMPLIANCE STATEMENT
(Tender / Consultant / Authority Ready)
HMS-based fire suppression solutions are suitable for lithium-ion battery fire risks by addressing thermal runaway, high heat release, and re-ignition characteristics, consistent with the risk-based selection principles of IS 2190, the safety objectives of AIS / CMVR for electric mobility, and the performance-based fire mitigation intent of NFPA 855.
5️⃣ TRAINING-FRIENDLY STANDARD SUMMARY
- IS 2190: Right agent for the right fire risk
- AIS / CMVR: Passenger safety & early intervention
- NFPA 855: Thermal runaway control & re-ignition prevention
- HMS: Heat-focused suppression aligned with all three
6️⃣ ONE-LINE VERSIONS (HIGHLY PRACTICAL)
- Tender:
- HMS complies with the risk-based fire protection intent of IS 2190 and NFPA 855 for lithium-ion battery hazards.
- Training:
- HMS aligns with global and Indian standards by controlling thermal runaway rather than only suppressing flames.
- Authority Presentation:
- HMS supports AIS and CMVR safety objectives for electric vehicles by enabling rapid, controlled battery fire mitigation.
