4 First Aid Measures
General Advice |
Seek medical advice immediately. Present this safety data sheet to the attending physician. Remove the affected individual from the hazard area. |
After Inhalation |
If inhaled, move the individual to fresh air. If breathing ceases, perform artificial respiration. Consult a doctor. |
After Skin Contact |
Remove contaminated clothing and footwear immediately. Wash the affected area with soap and plenty of water. Transport the individual to hospital promptly. A treatment with calcium gluconate paste is recommended. |
After Eye Contact |
Rinse eyes with water for at least 15 minutes, keeping eyelids apart. Continue rinsing during transport to hospital. |
After Ingestion |
Rinse mouth with water. Seek medical attention. Do not induce vomiting and never give anything to an unconscious person. |
5 Fire-fighting Measures
Suitable Extinguishing Media: Use spray water, alcohol-resistant foam, dry chemical, or carbon dioxide.
Fire-fighting Advice: During fire-fighting, use a self-contained breathing apparatus if necessary.
6 Accidental Release Measures
Personal Safety Precautions |
Wear respiratory protection. Prevent inhalation of vapours, mists or gases. Ensure adequate ventilation. Evacuate persons to a safe area. |
Environmental Protection Measures |
Prevent further leakage or spillage where it is safe to do so. Do not allow material to enter the environment without permission from the authorities. |
Cleaning/Recovery Procedures |
Clean immediately by sweeping up or vacuuming. |
For advice on safe handling, see Section 7.
For information on personal protective equipment, see Section 8.
For details on disposal, see Section 13.
7 Handling and Storage

Additional Information |
RTECS: YO7720000 Fluoride ions may reduce serum calcium levels and potentially cause fatal hypocalcaemia. The material is highly corrosive to mucous membranes of the respiratory tract, eyes and skin. It may cause spasms, inflammation and oedema of the larynx, bronchi and lungs, resulting in symptoms including burning, coughing, wheezing, laryngitis, shortness of breath and headaches. Symptoms may be delayed. Prolonged or repeated exposure may lead to nasal septum perforation and excessive calcification of bones, ligaments and tendons. Gastrointestinal irregularities have been observed in human evidence. |
