BERYLLIUM METALLIC 47

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: Grade 3; oral rat LD = 86 mg/kg; Lute Toxicity: Be produces a
chromic systematic disease that primarily affects the lung but also can involve other organs such as
lymph nodes, liver, bones, and kidney; Vapor (Gas) Irritant Characteristics: Data not available; Liquid
or Solid Irritant Characteristics: Data not available; Odor 17rreshold: Data not availabie.
Fire Hazards - Flash Point: Not flammable; Flammable Limits in Air (76): Not flammable; Fire
Extinguishing Agents: Not pertinent; Fire Extinguishing Agents Not To Be Used Do not use water on
adjacent fires; Special Hazards of Combustion Products: Toxic and irritating beryllium oxide fumes
and hydrogen chloride may form in fires; Behavior in Fire: No data; Ignition Temperature: Not
pertinent; Electrical Hazard Not pertinent; Burning Rate: Not pertinent.
Chemical Reactivity - Reactivity with Water: Reacts vigorously as an exothermic reaction. Forms
beryllium oxide and hydrochloric acid solution; Reactivity with Common Materials: Corrodes most
metals in the presence of moisture. Flammable and explosive hydrogen gas may collect in confined
spaces; Stability During Transporc: Stable; Neutralizing Agents for Acids and Caustics: Flush with
water and rinse with dilute solution of sodium bicarbonate or soda ash; Polymerization: Not pertinent;

Health Hazards Information - Recommended Personal Protective Equipment: Respiratory protection;
gloves; goggles; Qmptoms Following Exposure: Any dramatic weight loss should be considered as
possible first indication of beryllium disease. Inhalation causes irritation of nose, throat and lungs,
severe pneumonitis, andlor pulmonary edema. Ingestion causes fatigue, weakness, loss of appetite.
Contact with eyes causes severe irritation and burns. Contact with skin causes dermatitis and non-
healing ulcers; General Treatment for Exposure: INHALATION: move to fresh air, chest x-ray should
be taken immediately to detect pneumonitis, if exposure has been severe. INGESTION: induce
vomiting, get medical attention. EYES: flush with water for at least 15 min; get medical attention.
SKIN: flush with water; get medical attention if skin has been broken; 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: Grade 3; oral LD = 100 mg/kg (mouse); Lute Toxicity: Berylliosis of lungs
may occur from 3 months to 15 years after exposure. Chromic systemic diseases of the liver, spleen,
kidney, and other organs may also occur; Vapor (Gas) Irritant Characteristics: Data not available;
Liquid or Solid Irritant Characteristics: Data not available; Odor Threshold Data not available.
Fire Hazards - Flash Point: Not flammable; Flummable Limits in Air (9%): Not flammable; Fire
Extinguishing Agents: Not pertinent; Fire Extinguishing Agents Not To Be Used Not pertinent; Special
Hazards of Combustion Products: Toxic and irritating vapors may form from unburned material in a
fire situation; 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; .%ability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent;
Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
