Li-ion Gas Detection Recommended by FM Global
FM Global is one of the leaders in the property insurance and protection industry. Their goal is to reduce risk and prevent property loss within a variety of industries. Given their rise in prevalence, the recent focus has been lithium ion battery electrical energy storage systems. After thorough risk analysis, FM Global has released an update to their Property Loss Prevention Data Sheet 5-33.
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.
126.96.36.199 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.
188.8.131.52.1 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.
