Neutralizing Toxic Gases After Thermal Runaway Events
EticaAG offers complete thermal runaway protection. Suppressing fire with LiquidShield immersion cooling and neutralizing toxic gas with HazGuard.
The Challenge
Toxic Gasses Released From Thermal Runaway
Lithium-ion thermal runaway doesn’t stop at fire. It also releases flammable and toxic gases that threaten health, trigger emergency shutdowns, and delay permitting.
Most battery systems ignore this risk. Without a solution, developers face regulatory scrutiny, site restrictions, and safety blind spots that limit where and how energy storage can be deployed.

How HazGuard Works
1. Contaiment
Sealed modules capture off-gases at the source before they enter the enclosure.
2. Routing
Integrated gas routing manifold directs gases to HazGuard through a sealed pathway.
3. Neutralization
Proprietary physicochemical process neutralizes toxic and flammable battery gases.
4. Release
Neutralized gases are safely exhausted as inert air outside the enclosure.

The Complete Solution
The Only End-to-End Protection for Thermal Runaway
Our LiquidShield immersion cooling technology immediately suppresses thermal runaway, preventing fires from spreading to adjacent cells. By containing failure to a single cell, LiquidShield reduces toxic gas production, keeping your system safe from widespread hazards.
For any gases that are released, HazGuard takes over. It extracts, neutralizes, and safely releases toxic gases, ensuring a secure environment and minimal risk to personnel and infrastructure.
This is the only comprehensive solution for thermal runaway in Battery Energy Storage Systems. No flame, no fire, no propagation, and no toxic gas release. Just unparalleled safety, all in one system.
What types of gases does HazGuard neutralize?
HazGuard is designed to capture and neutralize the flammable and toxic gases released during a lithium-ion battery thermal runaway event, including hydrogen (H₂), carbon monoxide (CO), hydrogen fluoride (HF), and other volatile organic compounds.
How does HazGuard remove toxic gases from the BESS enclosure?
HazGuard uses an active extraction and filtration system that pulls gases out of the battery container, routes them through proprietary neutralization media, and safely vents inert, non-hazardous byproducts into the surroundings.
Does HazGuard activate automatically during an event?
Yes. HazGuard is designed to be always ready, with sealed battery modules that continuously contain and route off-gases directly into the system. Integrated temperature and gas sensors support automatic system activation and airflow management, enabling rapid neutralization without operator intervention.
How does HazGuard work with LiquidShield immersion cooling?
LiquidShield prevents fire propagation and minimizes gas generation by isolating thermal events to a single cell. HazGuard complements this by handling any gases that do form—capturing, neutralizing, and releasing them safely.
Is HazGuard required for permitting or code compliance?
While not universally required yet, HazGuard helps address growing AHJ concerns around gas emissions from lithium battery systems. It can simplify permitting in sensitive locations and align with emerging best practices in fire safety and toxic hazard mitigation.
Do all EticaAG BESS come with HazGuard?
HazGuard is standard across the EticaAG container and cabinet product lines. Every EticaAG system includes LiquidShield immersion cooling for fire suppression and containment, and HazGuard extends that protection with active toxic gas extraction and neutralization. This integrated approach is purpose-built for applications with zero tolerance for toxic gas emissions, including critical infrastructure, indoor installations, and sites with strict air quality or permitting requirements.
Where is the HazGuard mounted within the BESS container?
HazGuard is connected to a dedicated internal gas routing system that directs off-gases from the battery modules to a single exhaust interface. The HazGuard unit can be mounted on the top or side of the container or cabinet.
Can HazGuard be retrofit to existing containers?
Yes, HazGuard can be retrofit into existing containers.
