My recollection was that of the "big three" (HCl, H2SO4, and HNO3), nitric was the least worrisome.
HCl would outgas from solution, creating a noxious cloud, even diluted H2SO4 would sneakily concentrate itself by evaporation to a certain point, but except for the fuming variety, nitric would just make yellow stains and was washed off easily. It was a joke that you could tell chem majors by their yellow fingers.
