V           HEALTH HAZARD INFORMATION

Effects of Exposure:

Acute Effects:

Inhalation: May irritate respiratory system.

Ingestion: Ingestion of large amounts of lithium ion may cause vomiting, diarrhea, ataxia, intestinal irritation, kidney injury, CNS depression and drop in blood pressure. Central nervous system effects may include slurred speech, blurred vision, dizziness, sensory loss, convulsions and stupor.

Skin: May cause irritation.

Eye: May cause irritation.

Chronic Effects: Chronic intake of lithium ion may cause neuromuscular effects such as tremor, ataxia, weakness, clonus and hyperactive reflexes. Lithium ion can cause kidney damage, gastrointestinal disturbances, fatigue, dehydration, weight loss, dermatological effects and thyroid disturbances. Lithium ion has shown teratogenic effects in rats and mice. Chronic fluorine poisoning can cause severe bone changes, loss of weight, anorexia, anemia and dental defects.

Medical Conditions, if any, Aggravated by Exposure: None known

Most Likely Routes of Entry: Ingestion.

Carcinogenicity: NTP: No           IARC: No          OSHA: No         EPA: No

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION: Remove to fresh air. If not breathing, give artificial respiration. Call a physician immediately.

INGESTION: No data available but one should obtain medical attention.

SKIN: Remove contaminated clothing, flood with large amounts of water. If irritation persists seek medical attention.

EYE: Immediately flush eyes, including under eyelids, with large amounts of water for at least 15 minutes. Call a physician.
