Health Hazards Information - Recommended Personal Protective Equipment: Chemical safety
goggles; face shield; self-contained or air-line respirator; hard hat; foot protection; rubber gloves and
clothing; Symptoms Following Exposure: Vapor burns eyes and respiratory tract. Liquid is very
corrosive to body tissues because of reaction with water to form hydrochloric and phosphoric acids;
General Treatment for Exposure; CA KCION: persons doing treatment shouldprotect themselves against
exposure. INHALATION: remove victim from contaminated area at once; if breathing has stopped,
start artificial respiration; call a doctor. INGESTION: give water or milk; do NOT induce vomiting.
SKIN: remove contaminated clothing and flood exposed skin surfaces with water. EYES: retract eyelids
and wash with water for at least 15 min.; call a doctor; Toxicity by Inhalation (ThreshoMLimit Value):
0.5 ppm; Short-Ten Inhalation Limits: Data not available; Toxicity by Ingestion: Grade 3, oral rat
LD, = 380 mg/kg; Late Toxicity: Data not available; Vapor (&) Irritant Characteristics: Vapor
cause severe irritation of eyes and throat and can cause eye and lung injury. They cannot be tolerated
even at low concentrations; Liquid or Solid Im'tam Characteristics: Severe skin irritant. Causes second-
and third-degree burns on short contact and is very injurious to the eyes; Odor Ehreshold Data not
available.
Fire Hazards - Flash Point : Not flammable; Flammable Limits in Air (%): Not flammable; Fire
Extinguishing Agents: Sand and carbon dioxide on adjacent fires; Fire Exringuishing Agents Not to be
Used: Water; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire: Poisonous,
corrosive, irritating gases are generated when heated or when in contact with water; Ignition
Temperalure : Not flammable; Electrical Hazard Not pertinent; Burning Rate: Not flammable.
Chemical Reactivity - Reactivity with Water: Vigorous reaction with evolution of hydrogen chloride
fumes; Reactivity with Common Materials: Corrosive to most metals except nickel and lead. Products
of its reaction with water rapidly corrode steel and most metals with formation of flammable hydrogen
gas; Stability During Tmport: Stable; Neutralizing Agentsfor Acids and Caustics: Flush with water,
neutralize acids formed with lime or soda ash; Polymerization: Not pertinent; Inhibitor of
Polymerization: Not pertinent.
