V       HEALTH HAZARD INFORMATION



TLV: Not Set

LD50 Values for GaCl3: 306 mg/kg (subcutaneous-rat); 47 mg/kg (intravenous-rat). Not listed as a carcinogen by NTP, IARC.



Routes of Entry: Skin and eye contact, ingestion, inhalation. Gallium is not readily absorbed by the oral route. In animals, gallium

acts as a neuromuscular poison and causes renal damage. Gallium remains in tissues for long periods of time following intramuscular

injection of soluble salts.



EMERGENCY AND FIRST AID PROCEDURES:



SKIN: Wash thoroughly with soap and water.

EYES: Flush for at least 15 minutes with water. Call physician.

INGESTION: Call physician or poison control center.

INHALATION: Remove to fresh air.

Stability: Stable

Incompatibility (Material to Avoid): N/A

Hazardous Polymerization: Will not occur.

VII     SPILL OR LEAK PROCEDURES



Steps to Be Taken in Case Material Is Released or Spilled: Small amounts may be scooped or swept up, dissolved in water,

flushed down the drain with excess water. Avoid breathing dust.
