Eh, not so much.

That was a pretty large beeper he took into the elevator. /sarc
You know the situation, but for other that might be unaware, that was horrible.
You might not want to watch it.
It was a large bike battery in that closed elevator confined space however.
No explosion, just a sudden large very hot flash fire.
It burned that man so fast and there was nothing he could do.
These explosions were not due to lithium batteries.
However who knows what else was in it. Anyone near these explosions may have been “marked” and the cells and connections are now more evident.
