remove to fresh air. EYES: flush with copious amount of water for 15 min. SKIN: flush with water.
INGESTION: oral administration of aqueous 10 % solution of magnesium or sodium sulfate; for severe
intoxication, calcium or magnesium salt may have to be given i.v. with caution; treatment otherwise
is supportive and symptomatic; Toxicity by Inhalation (Threshold Limit Value): 0.5 mg/m3; Short-Tern
Exposure Limits: Data not available; Toxicity by Ingestion: Data not available; Lute Toxicity: Barium
poisoning; Vapor (Gas) Irritant Characteristics: Data not available; Liquid or Solid Irritant
Characteristics: Data not available; Odor Threshold Not pertinent.
Fire Hazards - Fhh Point: Not flammable but may cause fires upon contact with combustible
materials; Flammable Limits in Air (5%): Not pertinent; Fire Extinguishing Agents: Flood with water,
dry powder (e.g., graphite or powdered limestone); Fire Extinguishing Agents Not To Be Used Not
pertinent; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire: Can increase the
intensity of fires; Ignition Temperature: Not pertinent; Electrical Hazard Not pertinent; Burning Rate:
Not pertinent.
Chemical Reactivity - Reactivity with Water: Decomposes slowly but the reaction is not hazardous;
Reactivity with Common Materials: Corrodes metals slowly. If mixed with combustible materials or
finely divided metals, mixture can spontaneously ignite or become unstable by friction; Stability During
Transport: Sable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not
pertinent; Inhibitor of Polymerization: Not pertinent.

Health Hazards Information - Recommended Personal Protective Equipment: Chemical goggles and
chemical protective clothing. ; Symptoms Following Exposure: Inhalation of concentrated vapor can
irritate eyes, nose and throat. Liquid is irritating to the eyes. Prolonged contact with skin causes
irritation.; General Treatmentfor Exposure: SKIN, EYE CONTACT: Move the victim to fresh air and
contact doctor immediately. Wash contaminated skin area with water. Flush eyes with fresh running
water for at least 15 minutes. INGESTION: Induce vomiting and call a doctor.; Toxicity by Inhalm'on
(Threshold Limit Value): No data; Short-Tern Exposure Limits: No data; Toxicity by Ingestion: LD,,
0.5 to 5 g/kg; Late Toxicity:; Vapor (Gas) Im'tant Characteristics: Vapors can cause sever irritation
of eyes and throat and can cause eye and lung injury. They cannot be tolerated even at very low
concentrations.; Liquid or Solid Irritant Characteristics: Represents minimum hazard. If spilled on
clothing and allowed to remain, may cause smarting and reddening of the skin.; Odor Threshold: 0.042
