Yeah if you just dump a base into these strong acids things go foom! and you end up with dead makers.

Don't mix this stuff in dilution in an enclosed space either as the H2 gas can create another explosion hazard.

HF is technically a weak acid, but I wouldn't venture to neutralize it quickly; it's very reactive even if it doesn't fully dissociate in water.

As for hydrogen, neutralizing acids with bases doesn't generally produce it, but ventilation is still a good idea.
