Health Hazards Information - Recommended Personal Protective Equipment: Ammonia-type gas
mask; self-contained breathing apparatus; plastic-coated or rubber gloves, clothes, and apron; safety
shower must be available; Symptoms Following Exposure: Vapors cause itching, swelling, and
blistering of eyelids, skin, nose and throat; symptoms may be delayed for several hours. Temporary
blindness may occur. Liquid causes a caustic-like burn if not washed off at once. Ingestion or
absorption through skin causes nausea, dizziness, headache. Severe exposure may cause death; General
Treatment for Exposure: Call a doctor at once. INHALATION: remove to fresh air; observe for
development of delayed symptoms. Keep quiet. INGESTION: do not induce vomiting; give egg whites
or other emollient. SKIN OR EYES: wash with large amounts of water for at least 15 min.; Toxicity
by Inhalation (Threshold Limit Value): 1 ppm; Short-Term Inhalation Limits: 1 ppm for 30 min.;
Toxicity by Ingestion: Grade 3; LD,, 50 to 500 mg/kg (rat); Late Toxicity: Data not available; Vapor
(Gas) Irritant Characteristics: Vapor is moderately irritating such that personnel will not usually
tolerate moderate or high vapor concentrations; Liquid or Solid Irritant Characteristics: Severe skin
irritant. Causes second- and third-degree burns on short contact; very injurious to the eyes; Odor
Threshold Data not available.
Fire Hazards - Flash Point (deg. F): 126 OC; Flammable Limits in Air (5%): 4.7 - 100; Fire
Extinguishing Agents: Water, alcohol foam, dry chemical, or carbon dioxide; Fire Ectinguishing Agents
Not To Be Used: Not pertinent; Special Hazards of Combustion Products: Toxic vapors are generated
upon exposure to heat; Behavior in Fire: May explode if vapors are confined; Ignition Temperature :
May ignite spontaneously; Electrical Hazard: Not pertinent; Burning Rate: 1 mm/min.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: Can
catch fire when in contact with porous materials such as wood, asbestos, cloth, soil, or rusty metals;
Stability During Tramport: Stable at ordinary temperatures, however when heated this material can
decompose to nitrogen and ammonia gases. The decomposition is not generally hazardous unless it
occurs in confined spaces; Neutralizing Agents for Acids and Caustics: Flush with water and neutralize
the resulting solution with calcium hypochlorite; Polymerization: Not pertinent; Inhibitor of
Polymerization: Not pertinent.
