Guidance on Safe Use
Administrative data
First-aid measures
First-aid measures
-------------------
General information: In case of accident or if you feel unwell seek medical advice (show label or SDS where
possible).
After inhalation: Provide fresh air.
After contact with the skin: Wash with plenty of water or water and soap. In the event of a visible skin change or other
complaints, seek medical advice (show label or SDS where possible).
After contact with the eyes: Rinse immediately with plenty of water. Seek medical advice in case of continuous irritation.
After swallowing: Give several small portions of water to drink. Do not induce vomiting.
Advice for the physician: Allow cortisone spray inhalation at first possible opportunity.
Fire-fighting measures
Suitable extinguishing media: water mist , extinguishing powder , alcohol-resistant foam , carbon dioxide , sand .
Extinguishing media which must not be used for safety reasons: water spray , water jet .
Special exposure hazards arising from the substance or preparation itself, combustion products,
resulting gases: Hazardous decomposition products: alcohols . Do not allow extinguishing water to enter sewerage, the soil or inshore waters.
Special protective equipment for fire fighting: Use respiratory protection independent of recirculated air.
Accidental release measures
Personal precautions: Wear personal protection equipment (see section 8). Keep unprotected persons away. Avoid
contact with eyes and skin. Avoid inhaling mists and vapours. If material is released indicate
risk of slipping.
Environmental precautions: Prevent material from entering surface waters, drains or sewers and soil. Contain any fluid
that runs out using suitable material (e.g. earth). Retain contaminated water/extinguishing
water. Dispose of in prescribed marked containers.
Methods for cleaning up: Do not flush away with water. For small amounts: Absorb with a liquid binding material such as
diatomaceous earth and dispose of according to local/state/federal regulations. Contain larger
amounts and pump up into suitable containers. Clean any slippery coating that remains using a
detergent / soap solution or another biodegradable cleaner. Exhaust vapours.
Further information: Eliminate all sources of ignition.
Handling and storage
Handling:
-------------
Precautions for safe handling:
Ensure adequate ventilation. Keep away from incompatible substances in accordance with section
10.2. Spilled substance increases risk of slipping.
Precautions against fire and explosion: Flammable vapors may accumulate and form explosive mixtures with air in containers, process
vessels, including partial, empty and uncleaned containers and vessels, or other enclosed
spaces. Keep away from sources of ignition and do not smoke. Take precautionary measures
against electrostatic charging. Cool endangered containers with water.
Storage:
--------
Conditions for storage rooms and vessels: none known
Advice for storage of incompatible materials: not applicable
Further information for storage: Protect against moisture. Keep container tightly closed and store in a cool, well ventilated
place.

Exposure controls / personal protection
General protection and hygiene measures: Avoid contact with eyes and skin. Do not inhale gases/vapours/aerosols. Do not eat, drink or smoke when handling.
Personal protection equipment: Respiratory protection. In case of long or strong exposure: gas mask filter ABEK .
Hand protection: Protective gloves made of butyl rubber . Gloves suitable for up to 60 minutes' use.
Eye protection: tight fitting protective goggles .
Skin protection: protective clothing .
Exposure to the environment limited and controlled: Prevent material from entering surface waters and soil.
Further information for system design and engineering measures: Observe information in section 7.
Stability and reactivity
General information: If stored and handled in accordance with standard industrial practices no hazardous reactions are known.
Conditions to avoid: none known
Materials to avoid: Reacts with water in the presence of: basic substances and acids . Reaction causes the formation of: ethanol .
Hazardous decomposition products: If stored and handled in accordance with standard industrial practices and local regulations where applicable: none known . By hydrolysis: ethanol .
Disposal considerations
Material
Recommendation: Dispose of according to regulations by incineration in a special waste incinerator. Observe local/state/federal regulations.
Uncleaned packaging:
Recommendation: Completely discharge containers (no tear drops, no powder rest, scraped carefully). Containers may be recycled or re-used. Observe local/state/federal regulations.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
