First-aid measures
•Description of first aid measures
-General advice: First-aid crew: Ensure self-protection. Keep warm and in a quiet place. Take off contaminated clothing and shoes immediately. Move out of dangerous area.
-If inhaled: Provide fresh air. Keep the victim calm and in a semi-upright position. If symptoms persist, call a physician.
-In case of skin contact: Wash off immediately with plenty of water for at least 15 minutes. If symptoms persist, call a physician.
-In case of eye contact : Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Call a physician immediately.
-If swallowed : Rinse mouth with water. Immediately give large quantities of water to drink. Do NOT induce vomiting. Consult a physician.
•Most important symptoms and effects, both acute and delayed
-Symptoms: No information available.
•Indication of any immediate medical attention and special treatment needed
-Treatment: Treat symptomatically. For specialist advice physicians should contact the Poisons Information Service.

Fire-fighting measures
•Extinguishing media
-Suitable extinguishing media: Dry extinguishing media based on NaCl (e.g.Totalit M) or pul-verized limestone.
-Unsuitable extinguishing media: Water, Halons, Carbon dioxide (CO2)
•Special hazards arising from the substance or mixture
-Specific hazards during fire-fighting: Flammable. May form toxic gases on heating or in case of fire. Contact with water liberates extremely flammable gases. Hydrogen.
•Advice for firefighters
-Special protective equipment for firefighters: In the event of fire, wear self-contained breathing apparatus.
-Further information: Use water spray to cool unopened containers. Be aware of a dangerous reaction with water, if the container is ruptured. Collect contaminated fire extinguishing water separately. This must not be discharged into drains. Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations.
