EMERGENCY OVERVIEW
IMMEDIATE CONCERNS: White granular solid or powder, odorless. POTENTIAL HEALTH EFFECTS: Eye irritant; no significant hazard in
industrial/commercial applications.
COMMENTS:
(See Section 11, Toxicological Information)
4. FIRST AID MEASURES
EYES: Flush with water for at least 15 minutes. If irritation occurs and
persists, contact a medical doctor.
SKIN: Wash with plenty of soap and water. Get medical attention if
irritation occurs and persists.
INGESTION: Drink 1 or 2 glasses of water. Never give anything by
mouth to an unconscious person. If any discomfort persists, obtain medical
attention.
INHALATION: Remove to fresh air. If breathing difficulty or
discomfort occurs and persists, obtain medical attention.
NOTES TO MEDICAL DOCTOR: Lithium carbonate has low
toxicity and may produce moderate irritation. Treatment is symptomatic
and supportive.
5. FIRE FIGHTING MEASURES
FLAMMABLE LIMITS: Not applicable
GENERAL HAZARD: No known physical hazard, non-combustible.
EXTINGUISHING MEDIA: Dry chemical, CO2, water spray or
regular foam.
HAZARDOUS COMBUSTION PRODUCTS: None
FIRE FIGHTING PROCEDURES: Wear full protective clothing
and self-contained breathing apparatus (SCBA) approved for fire fighting.
This is necessary to protect against the hazards of heat, products of
combustion and oxygen deficiency. Do not breathe smoke, gases or vapors
generated.
AUTOIGNITION TEMPERATURE: Not applicable
PROPERTIES CONTRIBUTING TO FLAMMABILITY:
None

(See Section 10, Stability and Reactivity)
6. ACCIDENTAL RELEASE MEASURES
RELEASE NOTES: Sweep up and place in suitable container.
Dispose of waste according to local and Federal laws and regulations.
Before cleanup measures begin, review the entire MSDS with particular attention to Section 3, Emergency Overview and Potential Health Effects; and Section 8, Recommended Personal Protective Equipment. 7. HANDLING AND STORAGE
HANDLING: Avoid contact with eyes, skin or clothing. Use with
adequate ventilation. Wear safety glasses or goggles and rubber gloves.
Wash thoroughly after handling.
STORAGE: Keep away from strong acids. Keep container closed.
8. EXPOSURE CONTROLS / PERSONAL
PROTECTION
ENGINEERING CONTROLS: Use local exhaust ventilation to keep
airborne concentrations below exposure limits.
PERSONAL PROTECTIVE EQUIPMENT
EYES AND FACE: Safety glasses or goggles
RESPIRATORY: When engineering controls are not adequate, wear a
NIOSH/MSHA respirator approved for protection against inorganic dusts.
PROTECTIVE CLOTHING: Rubber gloves
WORK HYGIENIC PRACTICES: Quick-drench eyewash and
safety shower.

11. TOXICOLOGICAL INFORMATION
EYE EFFECTS: Moderately irritating (rabbit) [FMC I87-0998]
SKIN EFFECTS: Minimally irritating; PII = 0.3/8.0 (rabbit) [FMC
I87-0999]
DERMAL LD :
50 >2000 mg/kg (rat), [FMC I93-1799]
50 = 525 mg/kg (rat), [RTECS 1983]
INHALATION LC :
50 >0.80 mg/L (4 hr. rat); No mortality at
maximum attainable concentration, [FMC I93-1800]
SENSITIZATION: Non-sensitizer (guinea pig) [FMC I93-1801]
ACUTE EFFECTS FROM OVEREXPOSURE: Lithium
carbonate has low oral and dermal toxicity and is moderately irritating to
the eyes. It is not sensitizing and is essentially non-irritating to the skin.
CHRONIC EFFECTS FROM OVEREXPOSURE: The use of
this product in industrial and commercial applications presents no
significant toxicity hazard. The symptoms described below are based on
therapeutic applications where relatively large doses are taken orally by medically supervised patients. Lithium carbonate is used therapeutically at 500-2000 mg/day oral doses for specific mental disorders. Therapeutic effects occur at blood levels of 2.8 - 8.3 mg of lithium per liter. Minimal signs of toxicity may also occur at these therapeutic levels and involve primarily gastrointestinal upset. Increased dosage can produce tremors, drowsiness and unsteady gait. Signs of toxicity resolve rapidly on cessation of treatment. Prolonged treatment at toxic levels result in dehydration, kidney damage, weight loss and thyroid disturbances. Some studies of pregnant mice and rats were associated with birth defects but only at dose levels large enough to produce signs of severe maternal toxicity. Although data from the 1970's and 1980's suggested an increase in cardiovascular defects in babies born in women on lithium carbonate therapy, more recent studies have not found any association between lithium exposure and birth defects. Women receiving therapeutic lithium carbonate treatment at the time of confinement have the potential for delivery of a fetus with poor muscle tone, slowed heart rate and cyanosis. Full recovery usually occurs within 2-10 days postpartum. Therapeutic and greater levels of lithium may pose a risk to the conceptus and potential benefits to the mother are weighed carefully in clinical situations. Exposure to lithium in industrial settings is not considered to pose a risk to human health. NIOSH studied 25 workers exposed to lithium-containing dust at air concentrations exceeding 10 mg/m³ (nuisance dust limit) and found that typical industrial exposure to lithium will not result in blood levels sufficiently high to produce toxicity in either adults or their offspring.
