4 First Aid Measures
|
General information |
Consult a physician. Show this safety data sheet to the doctor in attendance. Move out of the dangerous area. |
|
After inhalation |
If breathed in, move the person into the fresh air. If not breathing, give artificial respiration. Consult a physician. |
|
After skin contact |
Take off the contaminated clothing and shoes immediately. Wash off with soap and plenty of water. Take the person immediately to the hospital. Consult a physician. Treatment with calcium gluconate paste is recommended. |
|
After eye contact |
Rinse opened eye for at least 15 minutes under running water. Continue rinsing eyes during transport to the hospital. |
|
After swallowing |
Rinse mouth with water. Consult a physician. Seek medical treatment. Do NOT induce vomiting. Never feed anything to an unconscious person. |
5 Fire Fighting Measures
Suitable extinguishing agents: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
Advice for firefighters: Wear self-contained breathing apparatus for firefighting if necessary.
6 Accidental Release Measures
|
Person-related safety precautions |
Wear respiratory protection. Avoid breathing vapors, mist, or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. |
|
Measures for environmental protection |
Prevent further leakage or spillage if safe to do so. Do not allow material to be released into the environment without proper governmental permits. |
|
Measures for cleaning/collecting |
Clean up promptly by sweeping or vacuuming. |
See Section 7 for information on safe handling.
