Very interesting, thank you. I expect there is an earlier step that can be taken by the designer of the installation to monitor the performance of the battery before or during off gassing that you can map to your system, I.e. the batteries are at a known state and there are many, so any deviation in a battery module will leave the tolerance of the “safe state” by means of monitoring electrically. Any deviant modules can then be verified by your system to say whether they are off gassing. There should be an isolation or removal of that module in any case. If it is off gassing then your method applies for the next steps.
My understanding is that Johnson Controls endorses the NFPA 18A 7.7 category Encapsulator Agent such as F-500EA to effectively suppress Li-Ion Battery fires and mitigate toxic off-gassing. Annex 4.3 addresses Li-Ion Battery fires.
This is a good presentation, but it needs updating to include newer suppression agents.
Didn't UL prove that sapphire doesn't work at all for lithium fires?
