V.  HEALTH HAZARD INFORMATION

Effects of Exposure:

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

Gallium and gallium compounds may cause metallic taste, skin rashes and depression of bone marrow function as well as anorexia, nausea and vomiting.  Large doses may cause hemorrhagic nephritis.

Acute Effects:

Inhalation:  May cause irritation to the mucous membranes of the respiratory tract.

Ingestion:  May cause anorexia, nausea and vomiting.

Skin:  May cause severe irritation.  Poison by subcutaneous and intravenous routes.

Eye:  May cause severe eye irritation.

Chronic Effects:

Inhalation:  May cause depression of bone marrow function.

Ingestion:  No chronic health effects recorded.

Skin:  May cause dermatitis and depression of bone marrow function.

Eye:  No chronic health effects recorded.

Medical Conditions Generally Aggravated by Overexposure:  No data found.

Carcinogenicity:  IARC:  No             NTP:  No               OSHA:  No

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult, seek medical attention if symptoms persist.

INGESTION:  Rinse mouth with water and spit.  Give 1-2 glasses of milk or water and induce vomiting, seek medical attention.  Never induce vomiting or give anything by mouth to an unconscious person.

SKIN:  Wash affected area with mild soap and water.  Seek medical attention if irritation develops or persists.
