Administrative data
First-aid measures
General advice:
Take off all contaminated clothing immediately. Never give anything by mouth to an unconscious person. Remove from exposure, lie down. In the case of accident or if you feel unwell, seek medical advice immediately (show the label where possible).
If inhaled : Remove to fresh air. Call a physician immediately.
In case of skin contact : Wash off immediately with soap and plenty of water.
In case of eye contact : In the case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
If swallowed : Clean mouth with water and drink afterwards plenty of water. If a person vomits when lying on his back, place him in the recovery position. Do NOT induce vomiting. If swallowed, seek medical advice immediately and show this container or label
Fire-fighting measures
Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
Unsuitable extinguishing media: High volume water jet
Special hazards arising from the substance or mixture
Specific hazards during firefighting: Cool closed containers exposed to fire with water spray. Do not allow run-off from fire fighting to enter drains or water courses.
Advice for firefighters
Special protective equipment for firefighters: Use personal protective equipment.
Further information: Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations.
Accidental release measures
Personal precautions, protective equipment and emergency procedures
Wear respiratory protection. Wear personal protective equipment.
Environmental precautions
Avoid subsoil penetration. Do not allow material to contaminate ground water system. Do not contaminate water.
If the product contaminates rivers and lakes or drains inform respective authorities. Do not let product enter drains.
Methods and materials for containment and cleaning up
Remove mechanically and with care (e.g. with clean polyethylene plastic shovel). Soak up with inert absorbent material (e.g. sand, silica gel, acid binder, universal binder, sawdust).
Other information
Never add other substances or waste material to product residue. Offer surplus and non-recyclable solutions to a licensed disposal company.
Handling and storage
Precautions for safe handling
Advice on safe handling: see personal protective equipment.
Dust explosion class: no data available
Conditions for safe storage, including any incompatibilities
Requirements for storage areas and containers: Electrical installations/working materials must comply with the technological safety standards. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Keep container tightly closed. No smoking.
Further information on storage conditions: Avoid impurities (e.g. rust, dust, ash), risk of decomposition.
Advice on common storage: Store apart from other dangerous and incompatible substances.
Storage temperature: 5 - 25 °C
Other data: Storing temperature for reasons of quality

Advice on disposal and packaging:
Disposal:
Dispose of in conjunction with appropriate waste disposal authorities
and in accordance with disposal regulations.
Waste codes should be assigned by the user based on the application
for which the product was used.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
