Suspected human carcinogen when contained in strong inorganic mists. A human poison. Experimental poison by inhalation. Moderately toxic by ingestion. A severe eye irritant. Extremely irritating, corrosive, and toxic to tissue, resulting in rapid destruction of tissue, causing severe burns. If much of the skin is involved, exposure is accompanied by shock, collapse, and symptoms similar to those seen in severe burns. Repeated contact with dilute solutions can cause a dermatitis, and repeated or prolonged inhalation of a mist of sulfuric acid can cause inflammation of the upper respiratory tract, leading to chronic bronchitis. Sensitivity to sulfuric acid or its mists or vapors varies with individuals. Normally 0.125–0.50 ppm may be mildly annoying, 1.5–2.5 ppm can be definitely unpleasant, and 10–20 ppm is unbearable. Workers exposed to low concentrations of the vapor gradually lose their sensitivity to its irritating action. Inhalation of concentrated vapor or mists from hot acid or oleum can cause rapid loss of consciousness with serious damage to lung tissue. Severe exposure may cause a chemical pneumonitis; erosion of the teeth due to exposure to strong acid fumes has been recognized in industry. An experimental teratogen.
This is a very powerful acidic oxidizer that can ignite or explode on contact with many materials, e.g., acetic acid, acetone cyanhydrin, (acetone + HNO3), (acetone + K2Cr2O7), acetonitrile, acrolein, acrylonitrile, (acrylonitrile + H2O), (alcohols + H2O2), allyl alcohol, allyl chloride, NH4OH, 2-amino ethanol, NH4, triperchromate, aniline, (bromates + metals), BrF5, n-butyraldehyde, carbides, CoHC2, chlorates, (metals + chlorates), ClF3, chlorosulfonic acid, Cu3N, diisobutylene, (dimethyl benzylcarbinol + H2O2), epichlorohydrin, ethylene cyanhydrin, ethylene diamine, ethylene glycol, ethylene imine, fulminates, HCl, H2, IF7, (indene + HNO3), Fe, isoprene, Li6Si2, Hg3N2, mesityl oxide, metals, (HNO3 + glycerides), p-nitrotoluene, perchlorates, HClO4, (C6H6 + permanganates), pentasilver trihydroxydiamino phosphate, (1-phenyl-2-methyl propyl alcohol + H2O2), P, P(OCN)3, picrates, potassium-tert-butoxide, KClO3, KMnO4, (KMnO4 + KCl), (KMnO4 + H2O), β-propiolactone, RbHC2, propylene oxide, pyridine, Na, Na2CO3, NaOH, steel, styrene monomer, water, vinyl acetate, (HNO3 + toluene). When heated it emits highly toxic fumes; will react with water or steam to produce heat; can react with oxidizing or reducing materials. When heated to decomposition it emits toxic fumes of SOx.
