"HF?"

In nasty quantities in the Moss Landing, AZ BESS fire, and recently the Otay Mesa fire that reignited and burned for nearly 3 weeks. Building it between the highschool, the tourism center and the only escape route is such a Texas thing for Vistra to do.

"Our quantitative study of the emission gases from Li-ion battery fires covers a wide range of battery types. We found that commercial lithium-ion batteries can emit considerable amounts of HF during a fire and that the emission rates vary for different types of batteries and SOC levels. POF3, on the other hand, was found only in one of the cell types and only at 0% SOC. The use of water mist as an extinguishing agent may promote the formation of unwanted gases as in eqs (2)–(3) and our limited measurements show an increase of HF production rate during the application of water mist, however, no significant difference in the total amount of HF formed with or without the use of water mist."
