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.
Immediate Medical Attention
Immediately call in physician.
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Small (incipient) fires must be extinguished with alcohol resistant foam, dry chemical powder or carbon dioxide.
Combustible. Pay attention to flashback. Vapours 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.
Cool containers with large amounts of water.
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
Do not breathe vapours, aerosols. Avoid substance contact. Ensure adequate ventilation. Keep away from heat and sources of ignition. Evacuate the danger area, observe emergency procedures, consult an expert.
Large spills should be collected mechanically (remove by pumping) for disposal.
Do not let product enter drains. Risk of explosion.
Take up with liquid-absorbent material (e.g. Chemizorb®). Dispose of properly. Clean up affected area.
Materials: liquid-absorbent material (e.g. Chemizorb®)

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
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. Handle and store under inert gas.
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.
Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
