Take off immediately all contaminated clothing.
In all cases of doubt, or when symptoms persist, seek medical advice.

Following inhalation
Provide fresh air.
If breathing is irregular or stopped, immediately seek medical assistance and start first aid actions.

Following skin contact
Rinse skin with water/shower.
Wash with plenty of soap and water.

Following eye contact
Rinse cautiously with water for several minutes.
Remove contact lenses, if present and easy to do. Continue rinsing. If eye irritation persists: Get medical advice/attention.

Following ingestion
Rinse mouth. Do not induce vomiting.
Get medical advice/attention if you feel unwell.

Notes for the doctor
none

none

Fire-fighting measures

5.1 Extinguishing media
Suitable extinguishing media
water mist, foam, alcohol resistant foam, fire extinguishing powder

Unsuitable extinguishing media
water jet

5.2 Special hazards arising from the substance or mixture
Hazardous decomposition products: Section 10.
Deposited combustible dust has considerable explosion potential. Self-heating: may catch fire.

Hazardous combustion products
nitrogen oxides (NOx), carbon monoxide (CO), carbon dioxide (CO2), hydrogen chloride (HCl)

5.3 Advice for firefighters
In case of fire and/or explosion do not breathe fumes.
Co-ordinate firefighting measures to the fire surroundings.
Do not allow firefighting water to enter drains or water courses. Collect contaminated firefighting water separately.
Fight fire with normal precautions from a reasonable distance.

Special protective equipment for firefighters
use suitable breathing apparatus

Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures
For non-emergency personnel
Remove persons to safety. Ventilate affected area.
Wearing of suitable protective equipment (including personal protective equipment referred to under
Section Exposure controls/personal protection of the safety data sheet) to prevent any contamination of skin, eyes and personal clothing.

For emergency responders
Wear breathing apparatus if exposed to vapours/dust/spray/gases.

6.2 Environmental precautions
Keep away from drains, surface and ground water. Retain contaminated washing water and dispose of it.

6.3 Methods and material for containment and cleaning up
Advices on how to contain a spill
take up mechanically, measures to prevent aerosol and dust generation

Advices on how to clean up a spill
Take up mechanically. Collect spillage.
Only vacuum cleaners containing no ignition sources may be used for combustible dusts.

Other information relating to spills and releases
Place in appropriate containers for disposal. Ventilate affected area.


Handling and storage

7.1 Precautions for safe handling
Measures to prevent fire as well as aerosol and dust generation
Use local and general ventilation.
Keep away from sources of ignition - No smoking.

Specific notes/details
Dust deposits may accumulate on all deposition surfaces in a technical room.

Handling of incompatible substances or mixtures
Keep away from
food, drink and animal feedingstuffs, oxidisers

Measures to protect the environment
Avoid release to the environment.

Advice on general occupational hygiene Do not eat, drink and smoke in work areas. Wash hands after use.
Preventive skin protection (barrier creams/ointments) is recommended.
Remove contaminated clothing and protective equipment before entering eating areas.

7.2 Conditions for safe storage, including any incompatibilities
Explosive atmospheres
Removal of dust deposits.

Flammability hazards
Keep away from sources of ignition - No smoking. Take precautionary measures against static discharge.

Incompatible substances or mixtures
Incompatible materials: see section 10. Observe hints for combined storage.
Protect against external exposure, such as
heat, humidity

Consideration of other advice
Keep away from food, drink and animal feedingstuffs.
Ventilation requirements
Provision of sufficient ventilation.
Specific designs for storage rooms or vessels
Storage temperature <40 °C

Packaging compatibilities
Only packagings which are approved (e.g. acc. to ADR) may be used.

7.3 Specific end use(s)
No information available.

Exposure controls / personal protection

8.1 Control parameters

Occupational exposure limit values (Workplace Exposure Limits)

Country Name of agent Notation Identifier TWA STEL Source
[mg/m³] [mg/m³]
GB dust i WEL 10 EH40/2005
GB dust r WEL 4 EH40/2005

8.2 Exposure controls
Appropriate engineering controls
General ventilation.

Individual protection measures (personal protective equipment) Eye/face protection
Wear eye/face protection.

Hand protection
Wear suitable gloves.
Chemical protection gloves are suitable, which are tested according to EN 374. Check leak-tightness/impermeability prior to use.
In the case of wanting to use the gloves again, clean them before taking off and air them well.
For special purposes, it is recommended to check the resistance to chemicals of the protective gloves mentioned above together with the supplier of these gloves.

Respiratory protection
In case of inadequate ventilation wear respiratory protection. Particulate filter device (EN 143).

Environmental exposure controls
Use appropriate container to avoid environmental contamination. Keep away from drains, surface and ground water.

Stability and reactivity

10.1 Reactivity
It's a reactive substance. Self-heating property.
If heated:
risk of ignition, danger of spontaneous combustion

10.2 Chemical stability
See below "Conditions to avoid".

10.3 Possibility of hazardous reactions
Self-heating: may catch fire.

10.4 Conditions to avoid
Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking.
The product in the delivered form is not dust explosion capable; the enrichment of fine dust however leads to the danger of dust explosion.

10.5 Incompatible materials
oxidisers

10.6 Hazardous decomposition products
Reasonably anticipated hazardous decomposition products produced as a result of use, storage, spill and heating are not known.
Hazardous combustion products: see section Fire-fighting measures.

Disposal considerations

Waste treatment methods
This material and its container must be disposed of as hazardous waste.
Sewage disposal-relevant information
Do not empty into drains.
Waste treatment of containers/packagings
It is a dangerous waste; only packagings which are approved (e.g. acc. to ADR) may be used. Handle contaminated packages in the same way as the substance itself.
