Description of first aid measures

Remove contaminated or saturated clothing.


If aerosol or mists are formed:

Move victims into fresh air.

If symptoms persist, call a physician.

Skin contact

Wash off with soap and water.

Eye contact

Rinse thoroughly with plenty of water keeping eyelid open.

In case of persistent discomfort: Consult an ophthalmologist.


Have the mouth rinsed with water.

After absorbing large amounts of substance / In case of discomfort: Supply with medical care.

Most important symptoms and effects, both acute and delayed


None known


None known

Indication of any immediate medical attention and special treatment needed

Specific therapy/antidote treatment: none known

After absorbing large amounts of substance:

administration of activated charcoal.

Acceleration of gastrointestinal passage

Fire-fighting measures

Suitable extinguishing media

water spray, foam, quenching powder, carbon dioxide (CO2)

Special hazards arising from the substance or mixture

May be released in case of fire: carbon monoxide, carbon dioxide, sulphur oxides, organic products of decomposition.

Special protective equipment for fire-fighters

In the event of fire, wear self-contained breathing apparatus.

Advice for firefighters

Water used to extinguish fire should not enter drainage systems, soil or stretches of water.

Ensure there are sufficient retaining facilities for water used to extinguish fire.

Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations.

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Wear personal protective equipment.

Environmental precautions

Do not allow entrance in sewage water, soil stretches of water, groundwater, drainage systems.

Methods and material for containment and cleaning up

Absorb with liquid-binding material e.g. sand, saw dust universal binder

Collect in suitable containers.

To be disposed of in compliance with existing regulations.

Additional advice

Isolate and seal off defective containers immediately.

Handling and storage


Precautions for safe handling

Local ventilation.

Always close container tightly after removal of product.

Ensure tightness at all times.

Advice on protection against fire and explosion

Take precautionary measures against static discharges.

Keep away from sources of ignition - No smoking.

Keep away from humidity.

Explosion protection is recommended in case the explosion limits for the following substance might be exceeded: Ethanol.

Danger of explosion from residual product fumes; therefore avoid spark production through cutting, grinding, or welding work in the area of the container.

When repairs of the production system are to be made (e.g. welding work), the section to be repaired must be essentially free of product.


Conditions for safe storage, including any incompatibilities

Keep containers tightly closed in a dry, cool and well-ventilated place.

Storage stability

12 month   10 - 40 °C

Exposure controls / personal protection

Control parameters

Engineering measures

Ensure suitable suction/aeration at the work place and with operational machinery.

see also section 7.

Personal protective equipment

Respiratory protection

In case of dusts/vapours/aerosols being formed or if the limit values like TLV are exceeded:

use respiratory equipment with suitable filter (filter type ABEK) or wear a self contained respiratory apparatus

Use only respiratory protection equipment with CE-symbol including four digit test number.

The filter class for the respirator must be suitable for the maximum expected contaminant concentration (gas/vapour/aerosol/particulates) that may arise when handling the product. If this concentration is exceeded, self-contained breathing apparatus must be used.

Note time limit for wearing respiratory protective equipment.

Hand protection

Wear protective gloves made from a tough material.

Glove material       for example, nitrile rubber

Material thickness       0,35 mm

Break through time       >= 480 min

Glove material       for example, Fluorinated rubber (Viton)

Material thickness       0,4 mm

Break through time       >= 480 min

Glove material       for example, butyl-rubber

Material thickness       0,5 mm

Break through time       >= 480 min

The information is based on our own tests, references from the literature and information from glove manufacturers, or derived by analogy with similar materials.

The rupture time and material thickness data are guideline values! Exact rupture time / material thickness data can be obtained from the protective glove manufacturer.

Please observe that the daily duration of usage of a chemical protective glove is in practice far shorter due to the many influencing factors (e.g. temperature, mechanical strain on the glove material) than the permeation time determined acc. EN 374.

Eye protection


Skin and body protection

Chemical protection suit, single-use protection suit (antistatic)


Hygiene measures

When using, do not eat, drink or smoke. Wash face and/or hands before break and end of work.

Remove contaminated or saturated clothing.

Wash contaminated clothing before re-use.

Preventive skin protection recommended.

Protective measures

The personal protective equipment used must meet the requirements of directive 89/686/EEC and amendments (CE certification).

It should be defined in the work place in the form of a risk analysis according to directive 89/686/EEC and amendments.

Avoid contact with skin, eyes and clothing.

If there is the possibility of skin/eye contact, the indicated hand/eye/body protection should be used.

If workplace exposure limits are exceeded and/or larger amounts are released (leakage, spilling, dust) the indicated respiratory protection should be used.

Do not breathe in vapours or aerosols.

Stability and reactivity

Possibility of hazardous reactions

When heated, formation of explosive vapour/air mixtures.

Incompatible materials

Reaction with water, acids and alcaline solutions., Formation of ethanol.

Hazardous decomposition products

Carbon monoxide, carbon dioxide (CO2), organic products of decomposition, Ethanol

Disposal considerations


Can be incinerated, when in compliance with local regulations.

Uncleaned packaging

Do not reuse empty containers and dispose of in accordance with the regulations issued by the appropriate local authorities.

Incorrect disposal or reuse of this container is illegal and can be dangerous.

If there is product residue in the emptied container, follow directions for handling on the container's label.

Other countries: observe the national regulations.

Waste Key Number

No waste key number as per the European Waste Types List can be assigned to this product, since such classification is based on the (as yet undetermined) use to which the product is put by the consumer.

The waste key number must be determined as per the European Waste Types List (decision on EU Waste Types List 2000/532/EC) in cooperation with the disposal firm / producing firm / official authority.
