Remove container from danger zone and cool with 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 vapors, 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.
Do not let product enter drains. Risk of explosion.
Take up carefully with liquid-absorbent material (e.g. Chemizorb®). Clean up affected area.
Materials: liquid-absorbent material (e.g. Chemizorb®)

Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU). Safety glasses
required when vapours/aerosols are generated. Our recommendations on filtering respiratory protection are based on the following standards: DIN EN 143, DIN 14387 and other accompanying standards relating to the used respiratory protection system. Recommended Filter type: Filter type AX The entrepeneur has to ensure that maintenance, cleaning and testing of respiratory protective devices are carried out according to the instructions of the producer. These measures have to be properly documented.
Flame retardant antistatic protective clothing.
Do not let product enter drains. Risk of explosion.
