SODIUM AMIDE
Chemical Designations - Synonyms: Sodamite; Chemical Fomla: NaNH2,
Observable Characteristics - Physical State (as nomlly shipped): Solid; Color: Gray; Odor: Like
a ammonia.
Physical and Chemical Properties - Physical State at 15 "c and I atm. : Solid; Molecular Weight:
39.01; Boiling Point ac I atm.: 752, 400, 673; Freezing Point: 410,210,483; Critical Tqemure:
Not pertinent; Critical Pressure: Not pertinent; SpeciJic Gravity: 1.39 at 20 "C (solid); Vapor (Gas)
Density: Not pertinent; Ratio of spec@ Heats of Vapor (Gas): Not pertinent; Latent Heat of
Vaporization: Not pertinent; Heat of Combustion: Not pertinent; Heat ofDecomposition: Not pertinent.
Health Hazards Information -Recommended Personal Protective Equipment: Goggles or face shield,
dust respirator; rubber gloves and shoes; Symptoms Following Exposure: Ammonia gas formed by
reaction of solid with moisture irritates eyes and skin. Solid causes caustic burns of eyes and skin.
Ingestion burns mouth and stomach in same way as caustic soda and may cause perforation of tissue;
General Treatment for Exposure: INGESTION: give water or milk followed by dilute vinegar or fruit
juice; do NOT induce vomiting; call a doctor. SKIN OR EYES: flood all affect areas with copious
amounts of water; Toxicity by Inhalation (ThresholdLimit Value): Not pertinent; Short-Term Exposure
Limits: Not pertinent; Toxicity by Ingestion: Data not available; Late Toxicity: None; Vqor (Gas)
Im'tant Characteristics: Only that of ammonia formed by reaction of solid with moisture in air; Liquid
or Solid Im*tant chamcrerisn'cs: Burns skin and eyes just like caustic soda; Odor Threshold: Not
pertinent.
Fire Hazards - Flash Point : Flammable solid; Flammable Limits in Air (96): Not pertinent; Fire
Extinguishing Agents: Dry soda ash, graphite, salt, or other recommended dry powder such as dry
limestone; Fire lktinguishing Agents Not To Be Used: Water; Qecial Hazards of Combustion Products:
Toxic and irritating ammonia gas may be formed in fires; Behavior in Fire: No data; Ignition
Temperature : Not pertinent; Electrical Hazard: No data; Burning Rate: Not pertinent.
Chemical Reactivity -Reactivity with Water: Reacts violently and often bursts into flames. Also forms
caustic soda solution; Reactivity with Comn Materials: No data; Stability During Transport: Stable;
Neutralizing Agents forAcids and Caustics: The caustic solution formed by the reaction with water can
be diluted with water and then neutralized by acetic acid; Polymerization: Not pertinent; Inhibitor of
Polymenm'on: Not pertinent.

SODIUM ARSENATE
Chemical Designations - Synonyms: Disodium arsenate heptahydrate; Sodium arsenate, dibasic;
Chemical Foda: Nz@~sO,*~O.
Observable Characteristies - Physical State (as normally shipped): Solid; Color: White; Odor: None.
Physical and Chemical Properties - Physical State at 15 "c and I atm. : Solid; Molecular Weight:
312; Boiling Point at 1 atm.: (decomposes) 356, 180, 453; Freezing Point: 135, 57, 330; Critical
Temperature: Not pertinent; Critical Pressure: Not pertinent; Qecijic Gravity: 1.87 at 20 "C (solid);
Vqor (Gas) Density: Not pertinent; Ratio ofSpecijTc Heats of Vqor (Gas): Not pertinent; Latent Heat
of Vaporizm'on: Not pertinent; Heat of Combustion: Not pertinent; Heat of Decomposition: Not
pertinent.
Health Hazards Information - Recommended Personal Protective Equipment: Dust mask, goggles or
face shield, protective gloves; Symptoms Following Exposure: Inhalation of massive doses can cause
laryngitis, bronchitis. Ingestion cause concentration in throat and difficulty in swallowing; also causes
burning and pain, vomiting, profuse diarrhea. Cyanosis, coma, convulsion, and death. Contact with
eyes causes irritation. Contact with skin causes various skin eruptions, more after as a late
manifestation, or chronic poisoning; General Treatment for Exposure: INHALATION: remove victim
from exposure; support respiration; INGESTION: gastric lavage with water, followed by 1 glass of
milk; consult physician. EYES: flush with water for at least 15 min. SKIN: flush with water; Toxicity
