LEAD NITRATE 233

LEAD IODIDE
Chemical Designations - Synonyms: No common synonyms; Chemical Formula: FbI,.
Observable Characteristics - Physical State (as shipped): Solid; Color: Bright yellow; Odor: None.
Physical and Chemical Properties - Physical State at 15 "c and I am. : Solid; Molecular Weigh?:
461.03; Boiling Point at I atm. : Not pertinent; Freezing Point: Not pertinent; Critical Temperature:
Not pertinent; Critical Pressure: Not pertinent; Specific Gravity: 6.16 at 20 "C (solid); Vapor (Gas)
Specific Gravity: Not pertinent; Ratio of Specific Heats of Vapor (Gus): Not pertinent; Latent Heat of
Vaporization: Not pertinent; Heat of Combustion: Not pertinent; Heat of Decomposition: Not pertinent.
Health Hazards Information - Recommended Personal Protective Equipment: Dust mask and
protective 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. Fain, 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 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 or SKIN: flush
with water; Toxicity by Inhalation (Thresholdfirnit Value): 0.2 mg/m3 (as lead); Short-Tern Inhalation
Limits: Data not available; Toxicity by Ingestion: Grade 2, LD,, 0.5-5 g/kg; Late Toxicity: Data not
available; Vapor (Gas) Irritant Characteristics: Data not available; Liquid or Solid Irritant
Characteristics: Data not available; Odor lkreshold 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: Not pertinent; 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 Aciak and Caustics: Not pertinent;
Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
