V           HEALTH HAZARD INFORMATION

Effects of Exposure:

              To the best of our knowledge the chemical, physical and toxicological properties of gallium oxide have not been thoroughly investigated and recorded.

              Gallium and gallium compounds may cause metallic taste, dermatitis and depression of the bone marrow function. Large doses may cause hemorrhagic nephritis.

Acute and Chronic Effects:

Inhalation: Mild respiratory irritant.

Ingestion: May effect peripheral nerves and sensation, causing flaccid paralysis without anesthesia. Behavioral changes such as somnolence and loss of appetite may be noted. Other symptoms may include nausea, vomiting, metallic taste in mouth, general itching and sweating.

Skin: May cause irritation

Eye: Dusts or powder may cause skin and eye irritation.

Carcinogenicity: NTP: No            IARC: No         OSHA: No

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION: Supply fresh air, if required, provide artificial respiration, keep warm. Seek immediate medical attention.

INGESTION: Have victim rinse mouth several times and spit out. Administer 1 or 2 glasses of water and induce vomiting. Seek medical attention.
