First Aid Measures
Emergency procedures for chemical exposure incidents
fresh air.
Take off immediately all contaminated clothing. Rinse skin with water/ shower.
rinse out with plenty of water. Remove contact lenses.
immediately make victim drink water (two glasses at most). Consult a physician.
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Water Foam Carbon dioxide (CO2) Dry powder
For this substance/mixture no limitations of extinguishing agents are given. For this substance/mixture no limitations of extinguishing agents are given.
Combustible. Vapors are heavier than air and may spread along floors. Forms explosive mixtures with air on intense heating. Development of hazardous combustion gases or vapours possible in the event of fire.
Suppress (knock down) gases/vapors/mists with a water spray jet.
Firefighter Protection
In the event of fire, wear self-contained breathing apparatus.

Stability and Reactivity
Chemical stability, hazardous reactions, and incompatible materials
The product is chemically stable under standard ambient conditions (room temperature).
Forms explosive mixtures with air on intense heating. A range from approx. 15 Kelvin below the flash point is to be rated as critical. The following applies in general to flammable organic substances and mixtures: in correspondingly fine distribution, when whirled up a dust explosion potential may generally be assumed.
