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).

- Inhalation : Remove to fresh air. Call a physician immediately.

- Skin contact : Wash off immediately with soap and plenty of water.

-  Eye contact : In the case of contact with eyes, rinse immediately with plenty of water and seek medical advice.

- Ingestion : 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.

- Extinguishing media which shall not be used for safety reasons: High volume water jet

- Specific hazards during fire fighting: Cool closed containers exposed to fire with water spray. Do not allow run-off from fire fighting to enter drains or water courses.

- Special protective equipment for fire-fighters: 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 : 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 for cleaning up : Remove mechanically and with care (e.g. with clean polyethylene plastic shovel). Contain and collect spillage with non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite) and place in container for disposal according to local / national regulations.

- Additional advice : Never add other substances or waste material to product residue. Move product residue to a safe place and dispose of properly.

Handling and storage


- Advice on safe handling : For personal protection see section 8.

- Advice on protection against fire and explosion: Avoid shock and friction. Keep away from heat and sources of ignition. Take necessary action to avoid static electricity discharge (which might cause ignition of organic vapours).


- 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 : < 10 °C

- Remarks : liquid up to -25 °C
