V. HEALTH HAZARD INFORMATION
Effects of Exposure:
To the best of our knowledge the chemical, physical and toxicological properties of calcium fluoride have not been thoroughly investigated and recorded.
Generally speaking, calcium compounds should be considered toxic only when they contain toxic components or as calcium oxide or hydroxide. Calcium compounds are common contaminates.
Inorganic fluorides are generally highly irritating and toxic. Chronic fluorine poisoning or “fluorosis,” occurs among miners of cryolite, and consists of sclerosis of the bones, caused by fixation of the calcium by fluorine. There may also be some calcification of the ligaments. The teeth are mottled, and there is osteosclerosis and ostemalacia. Large doses may cause very severe nausea, vomiting, diarrhea, aggravate attacks of asthma and severe bone changes, making normal movements painful. Some signs of pulmonary fibrosis are noted. Some enzyme system effects are reported. Irritants to the eyes, skin and mucous membranes. Loss of weight, anorexia, anemia, wasting and cachexia and dental defects are among the common findings in chronic fluorine poisoning. There may be an eosinophilia and impairment of growth in young workers. Symptoms of intoxication include gastric, intestinal, circulatory, respiratory, and nervous complaints and rashes. (Sax, Dangerous Properties of Industrial Materials)
Acute Effects:
Inhalation: May cause irritation to the respiratory tract and mucous membranes. May cause asthma attacks, excessive salivation, thirst, sweating, vomiting, cholic, diarrhea and lung granulomas.
Ingestion: Moderately toxic by intravenous route. May cause gastrointestinal irritation, nausea, vomiting, diarrhea, and cramp-like pain.
Skin: May cause irritation, rashes and skin granulomas.
Eye: May cause irritation.
Chronic Effects:
Inhalation: May cause fluorosis, pulmonary fibrosis and severe bone changes.
Ingestion: May affect the circulatory, enzyme and nervous system.
Skin: No chronic health effects recorded.
Eye: No chronic health effects recorded.
Primary Routes of Entry: Inhalation, ingestion, eye contact, skin contact
Target Organs: May affect the skeleton, eyes, skin, respiratory system, central nervous system, kidneys
Medical Conditions Generally Aggravated by Exposure: May cause or aggravate asthma attacks.
Carcinogenicity: NTP: No IARC: No OSHA Reg: No
EMERGENCY FIRST AID PROCEDURES:
INHALATION: Remove 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. Never give anything by mouth or induce vomiting in an unconscious person.
SKIN: Remove contaminated clothing, brush material off skin, wash affected area with mild soap and water. Seek medical attention if symptoms persist.
EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms persist.

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. Isolate spill area and provide ventilation. Vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal. Take care not to raise dust.
Waste Disposal Method: Dispose of in accordance with all Local, State and Federal regulations.
VIII. SPECIAL PROTECTION INFORMATION

IX. SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Store in cool, dry area. Keep container tightly closed. Wash thoroughly after handling.
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 or 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.
TSCA Inventory: Yes
Precautionary Labeling: WARNING! CAUSES IRRITATION. Avoid contact with eyes, skin, clothing. Keep in tightly closed container. Wash thoroughly after handling.
DOT Regulations:
Hazard Class: None
