Data platform availability banner - registered substances factsheets

Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

First-aid measures

Description of first aid measures

Observe self-protection

Remove victims from hazardous area.

Remove contaminated or saturated clothing immediately and dispose of safely.


If aerosol or mists are formed:

Consult a physician immediately.

Move victims into fresh air.

Do not leave victims unattended.

Keep patient warm and at rest.

Place person on side in stable position if unconscious.

Skin contact

Wash off immediately with plenty of water.

In case of complaints: Consult doctor immediately.

Eye contact

With eye held open, thoroughly rinse immediately with plenty of water for at least 10 minutes.

Protect unharmed eye.

Call ambulance. (Cue: caustic burn of the eyes)

Immediate further treatment in eye clinic/by eye doctor. continue rinsing eye until arrival at ophthalmic hospital.


Inform emergency physician immediately.

Only when patient fully conscious:

Have the mouth rinsed with water.

Do not leave victims unattended.

Keep warm and in a quiet place.

Place person on side in stable position if unconscious.

Most important symptoms and effects, both acute and delayed


None known


None known

Indication of any immediate medical attention and special treatment needed

If substance has been swallowed:

Gastric lavage, administration of activated charcoal, acceleration of gastrointestinal passage.

Fire-fighting measures

Suitable extinguishing media

foam, CO2

Unsuitable extinguishing media

alkali-containing extinguishing media

Special hazards arising from the substance or mixture

In case of fire cool endangered containers with water.

Closed container may rupture if strongly heated.

Special protective equipment for fire-fighters

In the case of fire, wear respiratory protective equipment independent of surrounding air and chemical protective suit.

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

Use personal protective equipment.

Do not inhale vapours / aerosols.

Leave room immediately.

Keep out unprotected persons.

Alert all persons!

Keep away from sources of ignition - No smoking.

Do not allow to enter drains (danger of explosion).

Environmental precautions

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

Cover over drainage system. Avoid penetration into drainage system or in rooms situated at a lower level because of danger of explosion.

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:       dry sand, diatomaceous earth

Handling and storage


Precautions for safe handling

If possible, use material transfer/filling, metering and blending plants that are closed.

Ventilators required at emission site.

Handle and open container with care.

Do not inhale vapours / aerosols.

Protect from moisture.

Store under lock and key or in a way that only skilled persons have access to it.

Advice on protection against fire and explosion

Take precautionary measures against static discharges.

Keep away from sources of ignition - No smoking.

Explosion protection equipment required.

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 cool, well-ventilated place.

Protect from moisture.

Comply with storage regulations and regulations prohibiting storage of hazardous substances in non-stationary containers in the same room (TRGS 510).

Exposure controls / personal protection

Control parameters

Engineering measures

If possible, use material transfer/filling, metering and blending plants that are closed, or provide for local suction devices.

Priority should be given to closed-system units.

in case of leakage: Extraction at the emission source required.

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 A) 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

Glove material       for example, Nitrile rubber/Nitrile latex (NBR)

Material thickness       0,35 mm

Break through time       >= 480 min

Glove material       for example, Fluorinated rubber (FKM)

Material thickness       0,4 mm

Break through time       >= 480 min

Method       Source: GESTIS substance database (hazardous substance information system of commercial professional associations)

Selection of protective gloves to meet the requirements of specific workplaces.

Suitability for specific workplaces should be clarified with protective glove manufacturers.

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

close-fitting protective goggles (e.g. closed goggles)

Skin and body protection

When handling larger quantities:

chemical protective suit

protective clothing made from non-flammable fibres, acid-proof


Hygiene measures

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

Remove immediately all contaminated clothing.

Wash contaminated clothing before re-use.

Cleanse skin with soap, then apply skin salve containing grease.

Protective measures

Handle in accordance with good industrial hygiene and safety practices.

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

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.

Use protective clothing / face shield if necessary.

Do not breathe in vapours or aerosols.

Avoid contact with skin and eyes.

Stability and reactivity

Possibility of hazardous reactions

decomposition (exothermic) with:




formation of: silane (Risk of spontaneous ignition).


Risk of explosion.

Hazardous decomposition products

Decomposition products from hydrolysis in water

Ethanol, hydrogen, silane

Disposal considerations


With respect to local regulations, e.g. taking special safety precautions dispose of to suitable waste incineration plant.

Uncleaned packaging

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

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

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

Other countries: observe the national regulations.
