Chemical Identifiers
)
UN/NA Number - The United Nations-North America number (also called UN number or DOT number). 4-digit number identifying an individual chemical or group of chemicals with similar characteristics. Required on shipping papers; often shown on placards or labels. This numbering system was developed by the U.S. Department of Transportation, and then became the UN standard system for classifying hazardous materials.
CAS Number - Chemical Abstracts Service registry number. Unique identification number assigned to this chemical by the American Chemical Society.
CHRIS Code - 3-letter code used by the U.S. Coast Guard to identify individual chemicals included in its CHRIS (Chemical Hazards Response Information System) manual.
DOT Hazard Label - U.S. Department of Transportation hazard warning label for the chemical (such as flammable liquid or corrosive). This label must be displayed on shipped packages, railroad tank cars, and tank trucks according to specifications described in 49 CFR 172.
NFPA 704 - Text description of the diamond-shaped placard, which contains codes indicating the level of the chemical's health, flammability, and reactivity hazards, along with special hazards such as water- and air-reactivity. (The NFPA 704 diamond is also shown at the top of the datasheet.) See a guide to the NFPA diamond.

Air & Water Reactions
Reacts exothermically and violently with water producing sulfuric acid, hydrochloric acid, and large quantities of dense white acid fumes [Merck, 11th ed., 1989]. Contact with water and metal produces explosive hydrogen gas [USCG, 1999].
Chlorosulfonic acid reacts vigorously with water to generate gaseous HCl. In experiments at Argonne National Laboratory, in which it was mixed with water and stirred at room conditions, about 85 percent of the theoretical yield of HCl evolved as a gas in the first 0.4 minutes [Brown, D. F., et al. (2000) Development of the Table of Initial Isolation and Protective Action Distances for the 2000 Emergency Response Guidebook, ANL-DIS-00-1, Argonne National Laboratory, Argonne IL].
Fire Hazard
Special Hazards of Combustion Products: Decomposes into irritating and toxic gases
Behavior in Fire: Although nonflammable, it may ignite other combustibles. Contact with water AND metal produces explosive hydrogen gas. (USCG, 1999)
Behavior in Fire: Although nonflammable, it may ignite other combustibles. Contact with water AND metal produces explosive hydrogen gas. (USCG, 1999)
Health Hazard
INHALATION: vapor extremely irritating to lungs and mucous membranes. Vapor has such a sharp and pentrating odor that inhalation of severely toxic quantities is unlikely unless it is impossible to escape the fumes. CONTACT WITH EYES OR SKIN: liquid acid will severely burn body tissue. (USCG, 1999)
Reactivity Profile
CHLOROSULFONIC ACID is a strong oxidizing acid. Reacts violently with water, strong mineral acids and bases, alcohols, finely dispersed organic matter. Dangerously incompatible with combustible materials, nitrates, chlorates, metallic powders, carbides, picrates, and fulminates. Undergoes possibly violent reactions with acetic acid, acetic anhydride, acetonitrile, acrolein, acrylic acid, acrylonitrile, alkali, allyl alcohol, allyl chloride, ammonium hydroxide, aniline, butyraldehyde, cresol, cumene, diethyleneglycol methyl ether, diisopropyl ether, diphenyl ether, ethyl acetate, ethyl acrylate, ethylene chlorohydrin, ethylenediamine, ethylene glycol, glyoxal, hydrocarbons (hexane, heptane), hydrogen peroxide, isoprene, powdered metals, methyl ethyl ketone, propylene oxide, vinyl acetate. When heated to decomposition, it emits toxic fumes of hydrogen chloride and oxides of sulfur [Sax, 9th ed., 1996, p. 831]. Reaction with phosphorus accelerates out of control and culminates in an explosion [Heumann, K. et al., Ber., 1882, 15, p. 417]. Mixing chlorosulfuric acid and 98% sulfuric acid may evolve HCl [Subref: Anon, Loss Prev. Bull. 1977, (013), 2-3].

Firefighting
Do not use water on material itself. Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. (AAR, 2003)
Non-Fire Response
Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Use water spray to knock-down vapors. Do not use water on material itself. Neutralize spilled material with crushed limestone, soda ash, or lime. Vapor knockdown water is corrosive or toxic and should be diked for containment. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquid with fly ash or cement powder. Neutralize with agricultural lime (CaO), crushed limestone (CaCO3) or sodium bicarbonate (NaHCO3). Dilute slowly with water. Water spill: Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). (AAR, 2003)
Protective Clothing
Acid-proof goggles or a rubber hood, long rubber gloves, rubber shoes, long rubber apron, shirt and trousers of wool or acrylic fiber, and a hat with a brim. For emergency use involving considerable exposure, a complete rubber suit with hood, gloves and boots of rubber should be used. In case of fire use self-contained breathing apparatus. (USCG, 1999)

First Aid
Call a physician in all cases.
INHALATION: remove victim to fresh air; if he is not breathing, apply artificial respiration; give oxygen if breathing is difficult; do NOT induce vomiting.
SKIN: flush with plenty of water for at least 15 min. while removing contaminated clothing and shoes. (USCG, 1999)
