To be fair, that’s the recommended way to put out an alkali metal fire. At least according to my grandfather who helped write safety regulations for nuclear subs whose reactors were cooled by liquid sodium.

Not really something I’d want to try out in practice, seems like a fire in a nuclear reactor under the ocean, where the source of the fire explodes on contact with water, is a less-than-ideal situation.

Not a bad metaphor for the times, though.
