V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

To the best of our knowledge the chemical, physical and toxicological properties of lithium orthosilicate have not been thoroughly investigated and reported.

The toxicity of lithium compounds is a function of their solubility in water.  Lithium ion has central nervous system toxicity.

Fluorides may cause salivation, nausea, vomiting, diarrhea and abdominal pain, followed by weakness, tremors, shallow respiration, convulsions and coma.  May cause brain and kidney damage.  Chronic fluoride poisoning can cause severe bone changes, loss of weight, anorexia, anemia and dental defects.

Acute Effects:

Inhalation:  May cause lithium poisoning, irritation to the respiratory tract and mucous membranes.  Dusts may cause asthma attacks and lung damage such as lung granulomas and pulmonary edema.  Large doses may cause immediate defecation, writhing, loss of muscle coordination, labored respiration, sedation, hypotension, dyspnea, hyperemia, liver edema and necrosis, portal congestion, pleural effusion and granulamatous peritonitis with serous and hemorrhagic ascites, respiratory and cardiac failure.

Ingestion:  Poison by ingestion.  May cause gastrointestinal irritation.

Skin:  May cause irritation.

Eye:  May cause irritation.

Chronic Effects:

Inhalation:  May cause lithium poisoning, fluorosis, pulmonary fibrosis, severe bone changes, hyperemia, cellular eosinophilia and vascular granulomata, acute chemical pneumonitis, subacute bronchitis and focal hypertrophic emphysema.

Ingestion:  May affect renal and hepatic functions, circulatory, enzyme and nervous system.

Skin:  May cause dermatitis, skin lesions and ulcerations.

Eye:  May cause corneal damage.

Medical Conditions, if any, Aggravated by Exposure:  Pre-existing respiratory, skin and gastrointestinal disorders.

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

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Remove victim to fresh air, keep warm and quiet, give oxygen if breathing is difficult and seek medical attention.

INGESTION: Give 1-2 glasses of milk or water, induce vomiting, seek medical attention immediately.  Never induce vomiting or give anything by mouth to an unconscious person. 

SKIN:  Remove contaminated clothing, brush material off of skin, wash affected area with mild soap and water.  Seek medical attention immediately.

EYES:  Flush with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes.  Seek medical attention immediately.

VI.   REACTIVITY DATA

Stability:  Stable

Conditions to avoid:  None

Materials to Avoid:  Acids, oxidizing agents.

Hazardous Decomposition:  Hydrogen fluoride, fluorine, and metal oxide fumes.

VII.   SPILL OR LEAK PROCEDURES

Steps to be Taken in Case Material is Released or Spilled:  Wear appropriate respiratory and protective equipment specified in section VIII.  Keep unprotected persons away.  Provide adequate ventilation. Vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for disposal.  Take care not to raise dust.

Waste Disposal:  Disposal should be made in accordance with all Federal, State and Local regulations.

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection:  NIOSH/MSHA approved dust mask for ordinary use, self-contained breathing apparatus for emergency use.

Ventilation:  Handle in a controlled, enclosed environment.  Handle and store under an inert gas such as argon.  Use local exhaust to maintain low exposure levels.  General exhaust is not recommended.

Protective Gloves:  Rubber

Eye Protection:  ANSI approved safety goggles

Other Protective Clothing or Equipment:  Normal lab wear.

IX.   SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage:  Keep container tightly closed.  Store in a cool, dry, well-ventilated area.  Wash thoroughly after use.

Other Precautions:  Handle and store under an inert gas such as argon.

Work Practices:  Implement engineering and work practice controls to reduce and maintain concentration of exposure at low levels.  Use good housekeeping and sanitation practices.  Do not use tobacco or food in work area.  Wash thoroughly before eating and smoking.  Do not blow dust off clothing or skin with compressed air.  Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
