First-aid measures

General: In all cases of doubt, or when symptoms persist, seek medical attention. Never give anything by mouth to an unconscious person.
After inhalation: Take the casualty into the fresh air and keep warm. Keep at rest. Irregular breathing/no breathing: artificial respiration.
Unconsciousness: lateral position - call a physician and show the label or datasheet.
After skin contact: Take off all contaminated clothing immediately. Wash away with soap and water and rinse. Do NOT use solvents or thinners. After eye contact: Remove contact lenses, keep eyelids open. Flush with plenty of water (10 - 15 min.).
After ingestion: Contact a doctor immediately. Keep at rest. Do not induce vomiting. Rinse mouth with water. Drink plenty of water. Obtain medical advice and show the label or datasheet if possible.

Fire-fighting measures

Suitable extinguishing media: Alcohol resistant foam, CO2, powders.
Unsuitable extinguishing media: Water.
Special risk posed by the substance or by the actual preparation, its combustion products or gases discharged: Build-up of pressure in closed containers. Danger that they might burst. Above flash-point, vapour is explosive when mixed with air. During fires, carbon monoxide, carbon dioxide, organic compounds and traces of inorganic substances may form. Exposure to decomposition products may cause a health hazard.
Special protective equipment: When extinguishing fires, use breathing apparatus with an independent source of air and wear full protective clothing.
Additional information: Cool endangered containers with water in case of fire.

Accidental release measures

Personal precautions: Remove ignition sources. Provide for sufficient ventilation. Do not inhale the vapour.
Environmental precautions: Avoid disposing the product into drainage/sewer system or directly into the aquatic environment.
Methods for cleaning up/collecting: Contain and collect spillage with non-combustible absorbent materials, e.g. sand, earth, vermiculite, diatomaceous earth and place in container for disposal according to local regulations. Avoid use of solvents.

Handling and storage

Information for safe handling: Prevent the creation of inflammable or explosive concentrations of vapour in air and avoid vapour concentrations higher than the OEL (=Occupational Exposure Limit). Additionally, the product should only be used in areas from which all naked lights and other sources of ignition have been excluded. Preparation may charge electrostatically: always use earthing leads when transferring from one container to another. Operators should wear antistatic footwear and clothing. No sparking tools should be used. Avoid contact with skin and eyes. Do not eat or drink during work - no smoking. Comply with the health and safety at work laws.
Requirements to be met by storerooms and containers: Store containers tightly closed in a cool, dry and well ventilated place. Never use pressure to empty: container is not a pressure vessel. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Prevent unauthorized access. No smoking. Keep away from oxidizing agents, from strongly alkaline and strongly acid materials. Always keep in containers of same material as the original one. See also instructions on the label. Avoid heating and direct sunlight.

Exposure controls / personal protection

Use as a transported isolated intermediate in a closed system in the synthesis of another substance following strictly controlled conditions as stated in Article 18 of Regulation (EC) No 1907/2006.
Respiratory protection: In case of accidental exposure: Filter type: AX, Colour code: Brown, Applications: Organic gasses and vapours with boiling point below 65°C.
Hand protection: In case of accidental exposure: Solvent-resistant protective gloves must be worn.
Eye protection: Use safety glasses.
Body protection: Personal should wear antistatic clothing made of natural fibre or of high temperature resistant synthetic fibre. All parts of the body should be washed after contact with the substance.

Stability and reactivity

Keep away from oxidizing agents, from strongly alkaline and strongly acid materials.

Disposal considerations

Contaminated packaging must be emptied of all residues and, following appropriate cleaning, may be sent to a recycling plant. Uncleaned packaging must be disposed of in the same manner as the medium.
