232 LEAD FLUORIDE

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 oz. 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 copious quantities of water for 15 min. SKIN: wash area with soap and water; treat as an
acid burn; Toxicity by Inhalation (ThresholdLimit Value): 0.2 mg/m3 (as lead); Short-Term Inhalation
Limits: Data not available; Toxicity by Ingestion: Grade 2, LD,, 0.5-5 glkg; Late Toxicity: Data not
available; Vqor (Gas) Im'tant Characteristics: Data not available; Liquid or Solid Im'tant
Characteristics: Data not available; Odor 2kreshold: Data not available.

Health Hazards Information - Recommended Personal Protective Equipment: Respirator for heavy
dust exposure; safety goggles; Symptoms Following Exposure: Not irritating to skin or mucous
membranes; protect against chronic poisoning. 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 causes irritation; 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 oz. 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 or SKIN: flush
with water; Toxicity by Inhalation (Threshold Limit Value): 0.15 mg/m3 (as lead); Short-Term
Inhalation Limits: Data not available; Toxicity by Ingestion: Grade 2, LD,, 0.5 - 5 glkg; Lute Toxicity:
