Could people conceivably keep a package of baking soda or calcium carbonate with them? would that be an effective on-the-spot antidote? Hmm or maybe get to the nearest kiosk and get some alka seltzer...

Potentially, but the neutralization of sulfuric acid releases a ton of heat (sometimes enough to crack glassware). By neutralizing the sulfuric acid without giving the heat anywhere to dissipate, you might just end up making things worse. Also, as a small unrelated note, I doubt calcium carbonate would work well for neutralizing sulfuric acid-- the calcium sulfate formed is for the most part insoluble and stops the reaction.

Best thing would probably be a lot of water. Here's a video of someone willingly pouring 98% sulfuric acid onto their hand, they just wash it off: https://youtu.be/XeVZQoJ5FdE?t=284 https://youtu.be/XeVZQoJ5FdE?t=284 . Plus, if someone pours a random liquid onto you, it's kind of hard to know if it's water, acid, lye...

  I was about to say that adding water would be bad in the case of lye, but after some research it seems I was wrong. Probably watched/read "Fight Club" too often. Apparently using an acid like vinegar to neutralize lye is more painful than flushing with water and creates a lot of heat because of the strong reaction.[1,2] So the recommendation actually is to just flush with water for 15 minutes.[3] [1]http://itonlyadds.blogspot.co.at/2012/08/on-chemical-burns-vinegar-and-liquefied.html http://itonlyadds.blogspot.co.at/2012/08/on-chemical-burns-v...
