In the section covering mechanical ventilation of battery systems, FM Global’s language makes a strong case for Li-ion Tamer. For example, our sensor is one of the only gas detectors to alarm simply in the presence of flammable gas. That’s because it generates a qualitative output rather than quantitative, like typical gas detectors.

Also, it’s worth noting that Li-ion Tamer’s recommended mitigating actions align with FM Global’s. Shutting down the ESS and increasing ventilation are two primary methods to prevent thermal runaway upon off-gas detection.

2.5.5.2 Install a combustible gas detector that will alarm at the presence of flammable gas (yes/no), shut down the ESS, and cause the switchover to full exhaust of the ventilation system.

2.5.5.2.1 Combustible gas detection in the ventilation system is not needed where combustible gas detection arranged for rack shutdown is provided in each ESS rack as part of the battery management system.

Although FM Global does not specifically name Li-ion Tamer, they have set the framework for Li-ion Tamer use in ESS for improved resilience. Because, utilizing off-gas detection to enact system shutdowns is the core functionality behind our technology. FM Global is leading the insurance industry with their recognition of gas detection as a crucial safety component in ESS. So, with the rest of the industry soon to follow, Li-ion Tamer is here to help meet their new requirements.
