V           HEALTH HAZARD INFORMATION

Effects of Exposure:

              To the best of our knowledge the physical, chemical and toxicological properties of lead fluoride have not been thoroughly investigated and recorded.

              Lead and lead compounds may cause abdominal pain, diarrhea, loss of appetite, metallic taste, nausea, vomiting, lassitude, insomnia, muscle weakness, joint and muscle pain, irritability, headache and dizziness. Red blood cells may be damaged resulting in anemia. Gastritis and injury to the kidneys, liver, male gonads, and central nervous system may also occur.

              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: Irritating to mucous membranes.

Ingestion: May cause metallic taste, nausea, headache muscle and joint pain, dizziness.

Skin: Irritation to skin

Eye: Irritating to eyes.

Target Organs: Affects nervous and reproductive systems, the urinary tract and blood.

Carcinogenicity: Probable human carcinogen.

Reproductive Effects: Affects both sexes reproductive abilities. Adverse affects on pregnancy (birth defects). Affects bone, kidney and hematopoietic systems.

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION: Remove to fresh air. If not breathing, give artificial respiration. Seek medical attention.

INGESTION: CALL A PHYSICIAN IMMEDIATELY. Give large amounts of water, and induce vomiting.

SKIN: Remove any contaminated clothing, brush material off of skin, flush with running water, wash carefully with soap and water. Seek Medical Attention.
