First Aid Measures
Emergency procedures for chemical exposure incidents
After inhalation: fresh air. 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.
Carbon oxides, Nitrogen oxides (NOx), Combustible. Vapours 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.
Remove container from danger zone and cool with water. Suppress (knock down) gases/vapours/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
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.
Do not let product enter drains.
Take up carefully with liquid-absorbent material (e.g. Chemizorb®).
Materials: liquid-absorbent material (e.g. Chemizorb®)

Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Full contact: Material: butyl-rubber, Minimum layer thickness: 0,7 mm, Break through time: 480 min, Material tested: Butoject® (KCL 898). Splash contact: Material: Latex gloves, Minimum layer thickness: 0,6 mm, Break through time: 60 min, Material tested: Lapren® (KCL 706 / Aldrich Z677558, Size M). When dissolving in or mixing with other substances and under conditions deviating from those stated in EN 16523-1 please contact the supplier of CE-approved gloves (e.g. KCL GmbH, D-36124 Eichenzell, Internet: www.kcl.de).
Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU). Safety glasses
Recommended Filter type: Filter A-(P2). The entrepreneur 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.
