SECTION 5: Firefighting measures
Suitable extinguishing media
Excerpt from ERG Guide 137 [Substances - Water-Reactive - Corrosive]: When material is not involved in fire, do not use water on material itself. SMALL FIRE: Dry chemical or CO2. Move containers from fire area if you can do it without risk. LARGE FIRE: Flood fire area with large quantities of water, while knocking down vapors with water fog. If insufficient water supply: knock down vapors only. FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Cool containers with flooding quantities of water until well after fire is out. Do not get water inside containers. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2016)
Specific hazards arising from the chemical
Special Hazards of Combustion Products: Toxic and irritating fumes of hydrogen fluoride and sulfuric acid may form in fires. Behavior in Fire: Contact with water applied to adjacent fires produces toxic, irritating fumes of hydrogen fluoride. (USCG, 1999)
Special protective actions for fire-fighters
NO water. In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT absorb in saw-dust or other combustible absorbents. NEVER direct water jet on liquid. Collect leaking and spilled liquid in sealable plastic containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

SECTION 10: Stability and reactivity
Reactivity
Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001). The substance is a strong acid. It reacts violently with bases and is corrosive. Reacts violently with water. This produces sulfuric acid and hydrogen fluoride. See Notes. Attacks glass in the presence of moisture.
Chemical stability
Fumes in moist air; stable to 900 deg c
Possibility of hazardous reactions
FLUOROSULFONIC ACID is very strongly acidic [Merck]. Reacts exothermically with chemical bases (examples: amines, amides, and inorganic hydroxides). These reactions can generate dangerously large amounts of heat in small spaces. Reacts violently with water to generate hydrofluoric acid and sulfuric acid. Reacts with active metals, including such structural metals as aluminum and iron, to release hydrogen, a flammable gas. Can initiate the polymerization of certain alkenes. Reacts with cyanide compounds to release gaseous hydrogen cyanide. Generates flammable and/or toxic gases in contact with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles, sulfides, and strong reducing agents. Additional gas-generating reactions occur with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), and carbonates. May catalyze (increase the rate of) chemical reactions.
Conditions to avoid
no data available
Incompatible materials
Reacts violently with water to generate hydrogen fluoride & sulfuric acid mists.
Hazardous decomposition products
See fluosulfonates. ...when heated to decomposition, they emit highly toxic fumes of fluorides and oxides of sulfur. ... fluosulfonates

Other Information
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.Rest and medical observation is therefore essential.Occupational exposures to mists and vapours from sulfuric acid are carcinogenic to humans.NEVER pour water into this substance; when dissolving or diluting always add it slowly to the water.
