First-aid measures

Description of 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.

Most important symptoms and effects, both acute and delayed

Any relevant information can be found in other parts of this section.

Indication of any immediate medical attention and special treatment needed

Fire-fighting measures

Extinguishing media

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 hazards arising from the substance or mixture

Hazardous decomposition products: alcohols . Do not allow extinguishing water to enter sewerage, the soil or inshore waters.

Advice for firefighters

Special protective equipment for fire fighting:

Use respiratory protection independent of recirculated air.

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Wear personal protection equipment (see section Exposure controls/personal protection). 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 and material for containment and 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.

Reference to other sections

Relevant information in other sections have to be considered. This applies in particular for information given on personal

protective equipment (section 8) and on disposal (section Disposal considerations).

Handling and storage

Precautions for safe handling

General information:

Avoid exposure by technical measures or personal protective equipment.

Precautions for safe handling:

Ensure adequate ventilation. Keep away from incompatible substances in accordance with section Stability and reactivity. Avoid breathing

dust/vapor/mist/gas/aerosol. Avoid contact with eyes, skin and clothing. Wash thoroughly after handling. 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.

Conditions for safe storage, including any incompatibilities

Conditions for storage rooms and vessels:

Use seal-tight containers.

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. Do not carry out refill operations

in storage rooms.

Specific end use(s)

No data are available.

Ethanol (CAS no. 64-17-5): Refer to Technical Rules for Hazardous Substances "TRGS 900" for more details on the German AGW.

Exposure controls

Exposure in the work place limited and controlled

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. Wash hands

at the end of work and before eating. Avoid exposure - obtain special instructions before use. Keep working clothes separately.

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. The selection of appropriate gloves not only

depends on the material, but also on other quality characteristics, and may vary depending on the manufacturer. Please observe

information from your glove supplier in terms of permeability and breakthrough time.

Eye protection

tight fitting protective goggles .

Skin protection

protective clothing, protective goggles/face protection . Clean work clothes regularly. After handling make sure skin is cleansed

and protected.

Exposure to the environment limited and controlled

Prevent material from entering surface waters and soil. Do not introduce large amounts into purification plants.

Further information for system design and engineering measures

Use only in closed systems. In the event of fill operations, ensure technical measures to minimise exposure.
