Special hazards arising from the substance or mixture

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

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

Soak up with inert absorbent material (e.g. sand, silica gel, acid binder, universal binder, sawdust).

Fill into marked, sealable containers.

To be disposed of in compliance with existing regulations.

Suitable binder:       sand (for damming up)

Additional advice

Isolate and seal off defective containers immediately.

Handling and storage

Handling

Precautions for safe handling

Local ventilation.

Always close container tightly after removal of product.

Advice on protection against fire and explosion

Take precautionary measures against static discharges.

Keep away from sources of ignition - No smoking.

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.

Keep away from humidity.

Storage

Conditions for safe storage, including any incompatibilities

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

Advice on common storage

Do not store together with: acids and alcaline solutions.

German storage class

Combustible / non-combustible liquids and solids not assigned to other storage classes.

Storage stability

10 - 40 °C  

Do not store longer than 12 months.

Exposure controls / personal protection

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       butyl-rubber

Material thickness       0,5 mm

Break through time       >= 480 min

Glove material       nitrile rubber

Material thickness       0,35 mm

Break through time       >= 480 min

Glove material       Fluorinated rubber (Viton)

Material thickness       0,4 mm

Break through time       >= 480 min

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

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

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

Safety glasses with side-shields

Skin and body protection

No special protective equipment required.

When handling larger quantities:

disposable protective suit

(Solvent-resistant)

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

Handle in accordance with good industrial hygiene and safety practices.

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

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

Do not breathe in vapours or aerosols.

Avoid contact with the skin and the eyes.

Stability and reactivity
