First-aid measures

Description of first aid measures

General information:

Take persons to a safe place. Observe self-protection for first aid. Always seek medical advice in the event of contact with this


After contact with the eyes:

Rinse immediately with plenty of water for 10-15 minutes. Keep eyelids well open to rinse the whole eye surface and eyelids with

water. Seek medical advice and clearly identify substance.

After contact with the skin:

Remove contaminated clothes at once. Wash off with plenty of water or water and soap immediately for 10-15 minutes. In serious

cases, use emergency shower immediately. Seek medical advice immediately and clearly identify substance.

After inhalation:

Keep the patient calm. If unconscious place in stable sideways position. Protect against loss of body heat. If breathing stops,

administer artificial respiration. Seek medical advice immediately and clearly identify substance.

After swallowing:

If conscious, give several small portions of water to drink. Do not induce vomiting. Seek medical advice immediately and clearly

identify substance.

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

Symptoms of poisoning may not become apparent until after many hours - medical monitoring is therefore required for at least 48

hours after any accident. Further toxicology information must be observed.

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. 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 has to be considered. This applies in particular for information given on personal protective

equipment and on disposal.

Handling and storage

Precautions for safe handling

Precautions for safe handling:

Avoid formation of aerosols. In case of aerosol formation special protective measures are required (exhausting by suction,

respiratory protection). Ensure adequate ventilation. Keep away from incompatible substances.

Spilled substance increases risk of slipping. Avoid contact with eyes, skin and clothing.

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:

none known

Advice for storage of incompatible materials:

Observe local/state/federal regulations.

Further information for storage:

Protect against moisture. Keep container tightly closed and store in a cool, well ventilated place.

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


The aerosol limit specified is a recommendation should aerosol be formed during processing.

Exposure controls

Exposure in the work place limited and controlled

General protection and hygiene measures:

Avoid exposure - obtain special instructions before use. 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. Keep away from foodstuff, drink and

feedingstuff. Remove contaminated, soaked clothing immediately.

Personal protection equipment:

Respiratory protection

In case of long or strong exposure: gas mask filter ABEK .

Eye protection

tight fitting protective goggles .

Hand protection

If dermal exposure cannot be excluded, appropriate gloves and protective clothing have to be worn. Recommendation: Protective

gloves made of butyl rubber . 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.

Skin protection

protective clothing .

Exposure to the environment limited and controlled

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

Waste Disposal Legislation Ref.No.(EC)

It is not possible to determine a waste code for this product in accordance with the European Waste Catalogue (EWC) since it is

only possible to classify it according to how it is used by the customer. The waste code is to be determined within the EU in liaison

with the waste-disposal operator.
