SECTION 3: Hazards Identification
Emergency Overview: Forms a corrosive alkaline hydroxide in contact with the human body. Lithium salts are toxic to the central nervous system and on repeated ingestion may damage kidneys and act as a teratogen
Primary Routes of Exposure: Ingestion, inhalation, skin and eyes
Eye Contact: Causes burning of the eyes resulting in redness and watering.
Skin Contact: Prolonged contact with moist skin causeschemical burns.
Inhalation: Causes burns to the nose, mucous membranes and respiratory tract.
Ingestion: Ingestion may lead to dizziness, abdominal cramps, vomiting, bloody diarrhea, weakness, and convulsions.
Acute Health Effects: Lithium salts are toxic to the central nervous system. Causes burns to skin, eyes and respiratory tract.
Chronic Health Effects: May cause kidney damage.
NTP: No
IARC: No
OSHA: No
SECTION 4: First Aid Measures
Eye Exposure: Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention.
Skin Exposure: Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists.
Inhalation: Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance.
Ingestion: Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel.
