pertinent.
Health Hazards Information - Recommended Personal Protective Equipment: Chemical cartridge
respirator; clean work clothes daily; gloves and eye protection.; Symptoms Following Exposure: Any
dramatic, unexplained weight loss should be considered as possible first indication of beryllium disease.
The dust is extremely toxic when inhaled; symptoms include coughing, shortness of breath, and acute
or chronic lung disease. There is no record of illness from ingestion of beryllium. Contact with dust
causes conjuctival inflammation of the eyes and dermatitis; General Treannent forrnosure: INHALA-
TION: acute disease may require hospitalization with administration of oxygen; chest x-ray should be
taken immediately. EYES: Flush with water followed by washing with soap and water; all cuts,
scratches or other injuries should receive prompt medical attention.; Toxicity by Inhalation (Threshold
Limit Value): 0.002 mg/m3; Short-Term Exposure Limits: 0.025 mg/m3 for 5 minutes; Toxicity by
Ingestion: LD,, 50 - 500 mglkg; Lute Toxicity: Beryllium disease may occur in the lungs, lymph
nodes, liver, spleen, kidney, and other organs.; Vapor (Gas) Irritant Characteristics: No data; Liquid
or Solid Irritant Characteristics: No data; Odor Z%reshold No data.
Fire Hazards - Flash Point: Not pertinent. This is a combustible solid; Flammable Limits in Air (96):
Not pertinent; Fire Extinguishing Agents: Graphite, sand, or any other inert dry powder; Fire
Extinguishing Agents Not To Be Used Water; Special Hazards of Combustion Products: Combustion
results in beryllium oxide fumes which are toxic to inhalation; Behavior in Fire: Powder may form
explosive mixture in air; Ignition Temperature (deg. F): Not pertinent; Electrical Hazard Not
pertinent; Burning Rate: Not pertinent.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: No
reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent;
Polymerizm*on: Not pertinent; Inhibitor of Polymerization: Not pertinent.

BERnLIUM NITRATE
Chemical Designations - Synonyms: Beryllium Nitrate Trihydrate; Chemical Formula:

Observable Characteristics - Physical State (as normally shipped): Solid; Color: White; Odor: None.
Physical and Chemical Properties - Physical State at 15 “c and I am.: Solid; Molecular Weight:
205.1 ; Boiling Point at I atm. : Not pertinent; Freezing Point: Not pertinent; Critical Temperature: Not
pertinent; Critical Pressure: Not pertinent; Specvc Gravity: 1.56 at 20°C (solid); Vqor (Gas) Density:
Not pertinent; Ratio of Specific Heats of Vapor (Gas): 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: Respiratory protection;
gloves; ffeshly laundered clothing; chemical safety goggles; Symptoms Following Exposure: Any
dramatic, unexplained weight loss should be considered as possible first indication of beryllium disease.
Inhalation causes pneumonitis, nasopharyngitis, tracheobronchitis, dyspnea, chronic cough. Ingestion
causes anorexia, fatigue, weakness, malaise. Contact with eyes causes dermatitis and non-healing
ulcers; General Treatment for Exposure: INHALATION: remove to fresh air; take chest x-ray
immediately to check the pneumonitis. INGESTION: induce vomiting; get medical attention. EYES:
flush with water for at least 15 min.; get medical attention. SKIN: cuts or puncture wounds in which
beryllium may be embedded under the skin should be thoroughly cleansed immediately by a physician;
Toxicity by Inhalation (Threshold Limit Value): 0.02 mg/m3 (as beryllium); Short-Tern Exposure
Limits: 0.025 mg/m3 less then 30 min.; Toxicity by Ingestion: Data not available; Late Toxicity: May
cause chronic systemic disease of the lung as well as other organs such as liver, spleen, lymph nodes,
bone and kidney; Vapor (Gas) Irritant Characteristics: Data not available; Liquid or Solid Irritant
Characteristics: Data not available; Odor Z%reshoM: Data not available.
