I dunno, Teslas going up in flames sometimes cause pretty dangerous fires - iirc in one instance they put a car wreck in a container full of water so the lithium could burn out overnight.

But, if something starts to go wrong it should have monitoring systems and an engineer can swap out the faulty module, and if it does go wrong I hope they have good containment.

But, not much you can do against a proper lithium battery / electrical fire I suspect.

Replace all air in the facility with Halon. That'll put out most fires.
