While working with some rust converter (MSDS, ~20% phosphoric acid by weight), a sequence of events that would make Rube Goldberg proud led to me spilling about 500mL of it all over the place. Yes I was wearing gloves and an acid gas respirator.
I'm not really well versed in chemical cleanup procedures and I needed to act fast so I kind of winged it by:
- Wiping the majority with a bath towel.
- There happened to be a box of baking soda right there so I dumped a bunch of it on the remaining spill.
- It fizzed for a bit then I wiped that up.
- I shop-vac'd the rest of the baking soda.
My question is just: Did I handle that OK? And, if not, how should I be prepared if that happens again? (I've been working with the chemical a lot lately.)
The reason I ask is, when I took off my respirator, it still smells like rust converter.
Also, it just happened so I won't be able to see any effects for a few hours but I'm hoping I don't start seeing rust spots on the metals it contacted, or dried crystals, or tear up any of the finish on the wood it contacted. But I'm hoping I got it.
Also, there are cats here and I don't really want residue to be left laying around.
So I'm wondering if that was a decent reaction, or if it was dangerous (I dunno what phosphoric acid + baking soda produces, although the space was well ventilated); and if it was effective, or if there is a better way.
Context is home shop, primarily woodworking; not a lab. So I don't have those nice metal lab tables or anything; lots of cracks, crevices, porous surfaces (concrete and wood), and stuff. And while I normally work with this stuff on a tray for small splash containment, this was a rather... violent spill (heh).
