Guidance on Safe Use

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.
