V HEALTH HAZARD INFORMATION
Effects of Exposure:
To the best of our knowledge the chemical, physical and toxicological properties of sodium hexafluoroaluminate has not been thoroughly investigated and reported.
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.
Aluminum may be implicated in Alzheimers disease. Inhalation of aluminum containing dusts may cause pulmonary disease.
Acute Effects:
Inhalation: Causes irritation
Ingestion: Swallowing will lead to a strong corrosive effect on mouth and throat and to the danger of perforation of esophagus and stomach. May cause nausea, vomiting, cramps and diarrhea. Large doses may cause CNS effects. Poisoning may affect the bladder, kidneys, heart and respiratory system.
Skin: Corrosive effect on skin and mucous membranes.
Eye: Strong corrosive effect.
Chronic Effects:
Inhalation: Inhalation of aluminum containing dusts may cause pulmonary disease. See also chronic effects of ingestion below.
Ingestion: Chronic exposure may effect the skeleton and may result in calcification of ligaments, tendons and muscle attachments to bone. May inactivate enzymes. May cause anorexia, anemia, dental defects and impairment of growth. May also cause gastric, intestinal, circulatory, respiratory and nervous disorders.
Skin: None known
Eye: None known
Other: High levels of aluminum in the brain may be implicated in senility and Alzheimer’s disease.
Medical Conditions, if any, Aggravated by the Chemical: Persons suffering from diseases of the lungs, kidneys or musculo-skeletal system.
Carcinogenicity: NTP: No IARC: No OSHA: No
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: Supply fresh air, if required, provide artificial respiration; keep patient warm. Seek immediate medical advice.
INGESTION: Do not induce vomiting. Seek immediate medical attention.
SKIN: Remove contaminated clothing, flood skin with large amounts of water, wash with soap and water. Seek medical attention.
EYE: Immediately flush eyes, including under eyelids, with large amounts of water for at least 15 minutes. Call a physician.
