Health Hazards Information - Recommended Personal Protective Equipment: Respirator approved
by U.S. Bureau of Mines for acid mists; rubber gloves; splashproof goggles; eyewash fountain and
safety shower; rubber footwear; face shield; Symptoms Follow@ Exposure: Acid mist is irritating to
eyes, nose and throat. Liquid causes severe burns of skin and eyes; General Treammt for Exposure:
INGESTION have victim drink water or milk; do NOT induce vomiting. EYES: flush with plenty of
water for at least 15 rnin.; call a doctor. SKIN: flush with plenty of water; Toxicity by Inhalation
(Threshold Limit Value): 1 mg/m3; Short-Tern Inhalation Limits: 5 mg/m3 for 5 min.; 3 mg/m3 for 10
min.; 2 mg/m3 for 30 rnin.; 1 mg/m3 for 60 min.; Toxicity by Ingestion: Severe burns of mouth and
stomach; Late Toxicity: None; Vapor (Gas) Im*tm Characteristics: Vapors causes a severe irritation
of the eye and throat and can cause eye and lung injury. They cannot be tolerated even at low
concentrations; Liquid or Sblid Irritant characteristics: Severe skin irritant. Causes second- and third-
degree burns on short contact; very injurious to the eyes; Odor Threshold: 1 mg/m3.
Fire Hazards - Flash Point: Not flammable; Flammable Limits in Air (96): Not flammable; Fire
Extinguishing Agents: Not pertinent; Fire Extinguishing Agents Not to be Used: Avoid use of water on
adjacent air; Special Hazards of Combustion Products: Toxic and irritating vapors are generated;
Behavior in Fire: Not pertinent; Ignition Temperature : Not flammable; Electrical Hazard Not
pertinent; Burning Rate: Not flammable.
Chemical Reactivity - Reactivity with Water: Vigorous reaction with water; spatters; Reactivity with
Common Materials: May react with cast iron with explosive violence. Attack many metals, releasing
flammable hydrogen gas. Capable of igniting finely divided combustible material on contact. Extremely
hazardous in contact with many materials; Stabiilify During Transport: Normally stable; Neutralizing
Agents for Acids and Caustics: Cautious dilution with water, with protection against violent spattering.
Diluted acid may be neutralized with lime or soda ash; Polymerization: Not pertinent; Inhibitor of
Polymrization: Not pertinent.
