Health Hazards Information - Recommended Personal Protective Equipment: Dust mask; 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 causes irritation of eyes and mild irritation of 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 useful 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 well with soap and water; Toxicity by
Inhulation (Threshold Limit Value): 0.2 mg/m3 (as lead); Short-Term Inhalation Limits: Data not
available; Toxicity by Ingestion: Grade 2, LD,, 0.5-5 glkg; Lute Toxicity: Data not available; Vapor
(Gas) Irritant Characteristics: Data not available; Liquid or Solid Irritant Characteristics: Data not
available; Odor Z%reshold 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; Special
Hazards of Combustion Products: Irritating sulfur dioxide gas may form in fire; Behavior in Fire: Not
pertinent; Ignition Temperature : Not pertinent; Electrical Hazard: Not pertinent; Burning Rate: Not
pertinent.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: No
reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent;
Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
