First-aid measures

Remove contaminated clothing.
If inhaled: If difficulties occur after dust has been inhaled, remove to fresh air and seek medical attention.
On skin contact: Wash thoroughly with soap and water.
On contact with eyes: Wash affected eyes for at least 15 minutes under running water with eyelids held open.
On ingestion: Rinse mouth immediately and then drink plenty of water, seek medical attention.
Indication of any immediate medical attention and special treatment needed
Treatment: Treat according to symptoms (decontamination, vital functions), no known specific antidote.

Fire-fighting measures

Suitable extinguishing media: dry powder, foam
Unsuitable extinguishing media for safety reasons: carbon dioxide
Additional information: Avoid whirling up the material/product because of the danger of dust explosion.
Advice for fire-fighters
Special protective equipment: Wear a self-contained breathing apparatus.
Further information:
The degree of risk is governed by the burning substance and the fire conditions. Contaminated extinguishing water must be disposed of in
accordance with official regulations.

Accidental release measures

Personal precautions, protective equipment and emergency procedures: Avoid dust formation. Use personal protective clothing.
Environmental precautions: Contain contaminated water/firefighting water. Do not discharge into drains/surface waters/groundwater.
Methods and material for containment and cleaning up
For small amounts: Pick up with suitable appliance and dispose of.
For large amounts: Contain with dust binding material and dispose of. Avoid raising dust.

Handling and storage

Precautions for safe handling
Breathing must be protected when large quantities are decanted without local exhaust ventilation.
Protection against fire and explosion: Avoid dust formation. Take precautionary measures against static discharges.
Conditions for safe storage, including any incompatibilities
Further information on storage conditions: Keep container tightly closed and dry; store in a cool place.

Exposure controls / personal protection

Occupational Exposure Limit
Personal protective equipment
Respiratory protection:
Suitable respiratory protection for lower concentrations or short-term effect: Particle filter with medium efficiency for solid and liquid particles
(e.g. EN 143 or 149, Type P2 or FFP2)
Hand protection:
Chemical resistant protective gloves (EN 374)
Suitable materials also with prolonged, direct contact (Recommended: Protective index 6, corresponding > 480 minutes of permeation time
according to EN 374):
e.g. nitrile rubber (0.4 mm), chloroprene rubber (0.5 mm), polyvinylchloride (0.7 mm) and other
Supplementary note: The specifications are based on tests, literature data and information of glovemanufacturers or are derived from similar
substances by analogy. Due to many conditions (e.g temperature) it must be considered, that the practical usage of a chemical-protective glove in
practice may be much shorter than the permeation time determined through testing. Manufacturer's directions for use should be observed
because of great diversity of types.
Eye protection:
Safety glasses with side-shields (frame goggles) (e.g. EN 166)
General safety and hygiene measures
Handle in accordance with good industrial hygiene and safety practice. Wearing of closed work clothing is recommended.

Stability and reactivity

Reactivity
No hazardous reactions if stored and handled as prescribed/indicated.
Formation of flammable gases: Remarks: Forms no flammable gases in the presence of water.
Chemical stability
The product is stable if stored and handled as prescribed/indicated.
Possibility of hazardous reactions
In spite of the dedusting carried out for reasons of industrial health the product resp. the fine dust of the
product is capable of dust explosion.
Conditions to avoid
Avoid dust formation. Avoid deposition of dust. Avoid sources of ignition.

Disposal considerations

Waste treatment methods
Must be disposed of or incinerated in accordance with local regulations.
Contaminated packaging:
Uncontaminated packaging can be re-used.
Packs that cannot be cleaned should be disposed of in the same manner as the contents.
