First Aid Measures
Emergency procedures for chemical exposure incidents
After inhalation: fresh air. Call in physician.
In case of skin contact: 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.
Caution if victim vomits. Keep airways free. Call a physician immediately.
Symptoms: Risk of aspiration! Pulmonary failure possible after aspiration of vomit.
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, 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.
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 vapours, aerosols. Avoid substance contact. Ensure adequate ventilation. 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®)

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. Keep locked up or in an area accessible only to qualified or authorised persons. Test for peroxide formation periodically and before distillation.
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.
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: Viton®, Minimum layer thickness: 0,7 mm, Break through time: 120 min, Material tested: Vitoject® (KCL 890 / Aldrich Z677698, 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 (acc. to DIN 3181) for vapours of organic compounds. 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.
Flame retardant antistatic protective clothing.
Do not let product enter drains. Risk of explosion.
