> Neutralization first, yes,

I'm not sure that "Neutralization first" is the best approach. My experiences with trying to neutralize spills of concentrated acids is that it takes much more neutralizer than one expects, leading to a major mess, and that the heat and splashes produced during the neutralization are a significant hazard unto themselves. I suspect that your idea of simply absorbing the spill into an inert solid to assist in packaging and disposal is a more practical approach.

Good luck.
