Health Hazards Information -Recommended Personal Protective Equipment: Goggles or face shield;
rubber gloves; Symptoms Following Exposure: Early symptoms of lead intoxication via inhalation or
ingestion are most commonly gastrointestinal disorders, colic, constipation, etc; weakness, which may
go on to paralysis, chiefly of the extensor muscles of the wrists and less often of the ankles, is
noticeable in the most serious cases. Ingestion of a large amount causes local irritation of the alimentary
tract. Pain, leg cramps, muscle weakness, paresthesias, coma, and death may follow in 1 or 2 days.
Contact with eyes cause severe irritation and can burn skin; General Treatment for Exposure: Remove
at once all cases of lead intoxication from further exposure until the blood level is reduced to a safe
value; immediately place the individual under medical care. INGESTION: give gastric lavage using
1 % solution of sodium or magnesium sulfate; leave 15-30 gm magnesium sulfate in 6-8 02. of water
in the stomach as antidote and cathartic; egg white, milk, and tannin are usehl demulcents; atropine
sulfate and other antispasmodics may relieve abdominal pain, but morphine may be necessary. EYES:
flush with water for at least 15 min. SKIN: wash contaminated skin with large amounts of water for
15 min.; Toxicity by Inhalation (Threshold Limit Value): 0.2 mg/m3 (as lead); Short-Tern Inhalation
Limits: Data not available; Toxicity by Ingestion: Grade 2, LD,, 0.5-5 glkg; Lute Taxicity: Data not
available; Vapor (Gas) Irritant Characteristics: Data not available; Liquid or Solid Irritant
Characteristics: Data not available; Odor Threshold: Data not available.
Fire Hazards - Flash Point : Not flammable; Flammable Limits in Air (%): Not flammable; Fire
Extinguishing Agents: Not pertinent; Fire Extinguishing Agents Not To Be Used: Not pertinent; gecial
Hazards of Combustion Products: Not pertinent; Behavior in Fire: Can increase the intensity of a fire
when in contact with combustible material. Cool containers with plenty of water; Zgnition Temperature

Chemical Reactivity - Reactivity with Water: Forms lead dioxide and acetic acid in a reaction that is
not violent; Reactivity with Common Materials: May corrode metals when moist; Stability During
Transport: Stable; Neutralizing Agents for Acids and Caustics: Dilute with water, rinse with dilute
sodium bicarbonate or lime solution; Polymerization: Not pertinent; Inhibitor of Polymrkation: Not
pertinent.
