Fire Hazards - Flash Point: Not combustible; Flammable Limits in Air (A): Not combustible; Fire
Extinguishing Agents: Water; Fire Extinguishing Agents Not To Be Used Not pertinent; Special
Hazards of Combustion Products: Toxic and irritating beryllium oxide and oxides of nitrogen may form
in fires; Behavior in Fire: May increase the intensity of fire when in contact with combustible
materials; Ignition Temperature: Not pertinent; Electrical Hazard Not pertinent; Burning Rate: Not
pertinent.

Health Hazards Information -Recommended Personal Protective Equipment: Respiratory protection;
gloves; freshly laundered clothing; chemical safety goggles; Symptoms Following Exposure: Dramatic,
unexplained weight loss may be considered as first indication of beryllium disease. Symptoms include
anorexia, fatigue, weakness, malaise. Inhalation causes pneumonitis, nasopharyngitis,
tracheobronchitis, dyspnea, chronic cough. Dust contact causes conjunctival inflammation of eyes and
skin irritation; General Treatment for Exposure: INHALATION 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): 0.002 mg/m3 (as beryllium); Short-Tern Exposure Limits: 0.025
mg/m3 less than 30 min.; Toxicity by Ingestion: No data; Late Toxicity: Beryllium disease may occur
in lymph nodes, liver, spleen, kidney, and lungs; Vapor (Gas) Irritant Characteristics: No data; Liquid
or Solid Irritant Characteristics: No data; Odor Threshold No data.
Fire Hazards - Flash Point: Not flammable; Flammable Limits in Air (A): Not flammable; Fire
Extinguishing Agents: Not pertinent; Fire Extinguishing Agents Not To Be Used Not pertinent; Special
Hazards of Combustion Products: Toxic beryllium oxide fume may form in fires; Behavior in Fire: Not
pertinent; Ignition Temperature: Not flammable; Electrical Hazard Not pertinent; Burning Rate: Not
flammable.
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;
Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
