Section 3 - Hazards Identification

Appearance: Clear solid/liquid mixture. Flash Point: -30 deg C.
Danger! Toxic. Causes digestive and respiratory tract burns. Extremely flammable liquid and vapor. Vapor may cause flash fire. Water-reactive. Corrosive. Causes severe eye and skin burns. Pyrophoric. Spontaneously flammable in air. Harmful if inhaled. Harmful if absorbed through the skin. Aspiration hazard if swallowed. Can enter lungs and cause damage. May cause central nervous system depression. May cause kidney damage. Air sensitive.
Target Organs: Kidneys, central nervous system.


Potential Health Effects
Eye: Causes severe eye burns. May cause irreversible eye injury.
Skin: Harmful if absorbed through the skin. Contact with liquid is corrosive and causes severe burns and ulceration.
Ingestion: Aspiration hazard. May cause central nervous system depression, kidney damage, and liver damage. Causes digestive tract burns with immediate pain, swelling of the throat, convulsions, and possible coma. Aspiration of material into the lungs may cause chemical pneumonitis, which may be fatal. May cause corrosion and permanent tissue destruction of the esophagus and digestive tract. May cause ear ringing, blurred vision, thyroid abnormalities, photophobia, coma, and seizures. The characteristics of lithium toxicity include: tremors, nausea, slurred speech, sluggishness, vertigo, thirst, and increased urine output. Effects from continued exposure include apathy, anorexia, fatigue, lethargy, muscular weakness, and cardiac changes. Long term exposure may lead to hypothroidism, leukocytosis, edema, weight gain, memory impairment, seizures, kidney damage, shock, hypotennsion, cardiac arrhythmias, coma, and death. Lithium has been implicated in the development of aplastic anemia.
Inhalation: Inhalation of high concentrations may cause central nervous system effects characterized by nausea, headache, dizziness, unconsciousness and coma. Irritation may lead to chemical pneumonitis and pulmonary edema. Causes severe irritation of upper respiratory tract with coughing, burns, breathing difficulty, and possible coma. May cause effects similar to those described for ingestion.
Chronic: Chronic inhalation and ingestion may cause effects similar to those of acute inhalation and ingestion.

Section 4 - First Aid Measures

Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid imme diately.
Skin: Get medical aid immediately. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion: Do not induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Possible aspiration hazard. Get medical aid immediately.
Inhalation: Get medical aid immediately. Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Notes to Physician: Treat symptomatically and supportively.

Section 5 - Fire Fighting Measures

General Information: Evacuate area and fight fire from a safe distance. Containers can build up pressure if exposed to heat and/or fire. As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Vapors can travel to a source of ignition and flash back. Combustion generates toxic fumes. Material is easily ignited if allowed to dry. Extremely flammable. Material will readily ignite at room temperature. Water Reactive. Material will react with water and may release a flammable and/or toxic gas. Use water spray to keep fire-exposed containers cool. Water may be ineffective. Material is lighter than water and a fire may be spread by the use of water. Can form explosive mixtures at temperatures above the flashpoint.
Extinguishing Media: Do NOT use water directly on fire. Water may be ineffective. Use water spray, dry chemical, carbon dioxide, or chemical foam.
Flash Point: -30 deg C ( -22.00 deg F)
Autoignition Temperature: 285 deg C ( 545.00 deg F)
Explosion Limits, Lower:1.40 vol %
Upper: 8.30 vol %
NFPA Rating: (estimated) Health: ; Flammability: ; Instability:

Section 6 - Accidental Release Measures

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Do not use combustible materials such as sawdust.

Section 7 - Handling and Storage

Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Ground and bond containers when transferring material. Do not get in eyes, on skin, or on clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Do not ingest or inhale. Do not allow contact with water. Use only in a chemical fume hood. Store and handle protected from air. Do not use if the material has evaporated to dryness. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Storage: Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Keep container closed to prevent drying out. Keep under a nitrogen blanket. Keep from contact with oxidizing materials. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from water. Keep away from organic halogens. Refrigerator/flammables. Keep containers tightly closed.

Section 8 - Exposure Controls, Personal Protection

Engineering Controls: Use adequate general or local explosion-proof ventilation to keep airborne levels to acceptable levels.
