b. Sulphuric acid and any preparation containing free or chemically unneutralized sulphuric acid (H !2! SO !4! ) in a concentration of ten per cent or more;

c. Nitric acid or any preparation containing free or chemically unneutralized nitric acid (HNO !3! ) in a concentration of five per cent or more;

d. Carbolic acid, otherwise known as phenol, and any preparation containing carbolic acid in a concentration of five per cent or more;

e. Oxalic acid and any preparation containing free or chemically unneutralized oxalic acid (H !2! C !2! O !4! ) in a concentration of ten per cent or more;

h. Hypochlorous acid, either free or combined, including calx chlorinata, bleaching powder, chloride of lime, chlorinated soda, and chlorinated potash, and any preparation containing any of such substances so as to yield a concentration of ten per cent or more of available chlorine;
