Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
First-aid measures
breathing give artifical respiration. If breathing is
difficult administer oxygen. Seek medical attention.
Emergency measure - Eyes: Hold eyelids apart and flush with plenty of water for
15 minutes. Seek medical attention.
Emergency measure - Skin: Remove any contaminated clothing. Wash skin thoroughly with
soap and water. If signs of irritation (redness, swelling,
itching, etc) develop or persist, seek medical attention.
Emergency measure - Ingestion: Seek medical attention immediately. Never give anything by
mouth to an unconscious person.
Fire-fighting measures
Product arising from burning: Carbon monoxide, carbon dioxide, nitrogen oxides, hydrogen
chloride
Product determined by test: N
Protective equipment: Firefighters should wear self-contained breathing apparatus,
flame and chemical resistant clothing, boots and gloves.
Evacuate personnel to upwind direction, remove unneeded ma-
terial and cool container(s) with water from maximum dis-
tance.
Accidental release measures
using a high efficiency particulate air filtered vacuum
cleaner or moisten and pick-up so as to minimise dust ge-
neration. Place into a suitable container which must be
tightly closed and labelled according to TRGS 201.
Dispose of according to local regulations.
The spill area should be cleaned thoroughly with detergent
and water and ventilated after material has been picked up.
A laboratory coat or gown, latex or nitrile gloves, a respi-
rator with HEPA filters or cartridges and eye protection
should be worn as a minimum precaution. Additional protec-
tive clothing/ equipment may be needed depending on the
quantity spilt and the extent of the spill.
Handling and storage
by skin contact is minimized. Eye contact and inhalation of
the substance should be avoided.
Where possible, use closed or at least dustproof equipment
during filling, transfer, metered feeding, and sampling.
In the case of handling the substance in open systems, ex-
tract any dust which forms, directly at the point of origin.
If technical extraction or ventilation measures are not pos-
sible or are insufficient, suitable respiratory protection
(e. g. :::) should be worn.
To avoid any skin contact, tested protective gloves (e. g.
:::) and, if applicable, suitable protective clothing (e. g.
:::) have to be worn.
The wearing of eye protection (e. g. safety goggles) is re-
commended.
Adequate washing facilities should be provided in the imme-
diate vicinity of the working area.
After contact with the skin, the affected parts of the body
should be thoroughly cleaned instantly using soap and water.
Special skin-protection and skin-care measures are recom-
mended.
A skin-protection plan should be drawn up.
In cases where dusts can form, due to the potential dust-
explosion risk, potential sources of ignition should be re-
moved from the working area. In addition, measures should
be taken to prevent electrostatic discharges.
Storage: Store the substance at room temperature in the original
packing drums or other secure containers which are labelled
according to the regulations. Keep them tightly closed and
secure them against falling by taking the appropriate mea-
sures.
Avoid residues on the outside of the containers.
Packaging of the substance and or preparation: Fibre drum, 30 kg.

Special provisions / remarks
- Remarks:
- Transport: For in-plant transport use the original packaging or other
secure containers which are labelled according to the regu-
lations.
Keep them tightly closed and secure them against falling by
taking the appropriate measures.
In event of a spillage, observe the warning labels on the
containers.

Exposure controls / personal protection
Stability and reactivity
Compound is expected to be unstable in acid and alkaline,
however this is not expected to result in a hazardous
situation.
Chemical reaction with water: None known.
Dust explosion: The material is considered to have a weak to moderate dust
explosion potential. Fine powders are considered to be com-
bustible. Provide appropriate bonding and grounding protec-
tion to control static charges.
Powder handling systems such as dust collectors, dryers,
and mills may require additional protective measures
(i.e. explosion venting).
Dust explosion determined by test: N
Disposal considerations
from minor spillages or accidental discharge is not
economically or technically feasible, and waste material
will be disposed of by incineration. In principle, it may be
possible to recover larger spillages of uncontaminated
material for subsequent use.
Industry - Possibility of neutralisation: No chemical treatment is practicable to neutralise the
hazardous health or environmental properties.
Industry - Possibility of destruction: controlled discharge: Contaminated containers may be disposed of by incineration.
Industry - Possibility of destruction - incineration: The substance can be disposed of by incineration by burning
under controlled conditions at a licensed waste treatment
processor in accordance with local regulations. Stack gases
should be scrubbed.
Industry - Possibility of destruction - water purification: The substance should not normally be discharged directly
to the sewage system or the aqueous environment. However,
adverse effects on sewage treatment systems would be un-
likely.
Industry - Possibility of destruction - other: None known.
Public at large - Possibility of recovery/recycling: Not applicable.
