I bet there are about 1000 ways to accidentally kill yourself or others in this book from 1910: The Scientific American cyclopedia of formulas.
It includes chapters on fireproofing, bleaching, metallurgy, brazing metals, insecticides(!) and opens (appropriately) with an excellent chapter on first aid in the 1910’s.
At least killing yourself in the pursuit of scientific progress has a certain romance to it, a martyr for Knowledge like Marie Curie. A little knowledge can be a dangerous thing.
