While I do not argue the explosive nature of it, safety can be improved by embracing how fast it disperses. Think Toyota went that path with interleaved fibers in their containers' outer enclosures, to augment that effect, so it isn't sufficient for an explosion to occur.

(Edit: added Toyota's test where they shot an hydrogen tank, you can see the fibers and the gas dispersion)
