First Aid Measures
Emergency procedures for chemical exposure incidents
After inhalation: fresh air. If breathing stops: mouth-to-mouth breathing or artificial respiration. Oxygen if necessary. Immediately call in physician.
Take off immediately all contaminated clothing. Rinse skin with water/ shower. Consult a physician.
After eye contact: rinse out with plenty of water. Call in ophthalmologist. Remove contact lenses.
After swallowing: immediately make victim drink water (two glasses at most). Consult a physician.
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Water, Foam, Carbon dioxide (CO2), Dry powder
For this substance/mixture no limitations of extinguishing agents are given.
Combustible. Fire may cause evolution of: nitrogen oxides, Hydrogen cyanide (hydrocyanic acid). Pay attention to flashback. Vapors are heavier than air and may spread along floors. Development of hazardous combustion gases or vapours possible in the event of fire. Forms explosive mixtures with air at ambient temperatures.
Remove container from danger zone and cool with water. Suppress (knock down) gases/vapors/mists with a water spray jet.
Firefighter Protection
Stay in danger area only with self-contained breathing apparatus. Prevent skin contact by keeping a safe distance or by wearing suitable protective clothing.
Accidental Release Measures
Spill cleanup procedures, containment, and environmental protection
Evacuate the danger area, observe emergency procedures, consult an expert.
Do not let product enter drains. Risk of explosion.
Take up with liquid-absorbent material (e.g. Chemizorb®). Clean up affected area.
Materials: liquid-absorbent material (e.g. Chemizorb®)

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Avoid contact with skin and eyes. Avoid inhalation of vapor or mist. Filled under nitrogen. Work under hood. Do not inhale substance/mixture. Avoid generation of vapours/aerosols.
Keep container tightly closed in a dry and well-ventilated place. Keep away from heat and sources of ignition.
Immediately change contaminated clothing. Apply preventive skin protection. Wash hands and face after working with substance.
Keep away from open flames, hot surfaces and sources of ignition. Take precautionary measures against static discharge.
