First-aid measures

General notes
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
After contact with skin, wash immediately with plenty of water.
If skin irritation or rash occurs: Get medical advice/attention.

Following eye contact
Rinse cautiously with water for several minutes.
Remove contact lenses, if present and easy to do. Continue rinsing.

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

Fire-fighting measures

Extinguishing media
Suitable extinguishing media
water, foam, alcohol resistant foam, fire extinguishing powder
Unsuitable extinguishing media
water jet

Special hazards arising from the substance or mixture
Hazardous decomposition products: Section 10.
Danger of dust explosion.
Deposited combustible dust has considerable explosion potential.
Hazardous combustion products
nitrogen oxides (NOx), carbon monoxide (CO), carbon dioxide (CO2)

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

Personal precautions, protective equipment and emergency procedures
For non-emergency personnel
Remove persons to safety.
Ventilate affected area.
Control of dust.
Eliminate all ignition sources if safe to do so.
Wearing of suitable protective equipment (including personal protective equipment referred to under
Section 8 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.

Environmental precautions
Remove from the water surface (e.g. skimming, sucking).
Keep away from drains, surface and ground water.
Retain contaminated washing water and dispose of it.

Methods and material for containment and cleaning up
Advices on how to contain a spill
covering of drains, take up mechanically
Advices on how to clean up a spill
Take up mechanically.
Collect spillage.
Other information relating to spills and releases
Place in appropriate containers for disposal.
Ventilate affected area.

Handling and storage

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.
Take precautionary measures against static discharge.
Only vacuum cleaners containing no ignition sources may be used for combustible dusts.
Use explosion-proof electrical/ventilating/lighting/equipment.
Use only non-sparking tools.
Specific notes/details
Layers, deposits and heaps of combustible dust must be considered, like any other source which can
form a hazardous explosive atmosphere.
Dust deposits may accumulate on all deposition surfaces in a technical room.
Danger of dust explosion.
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.

Conditions for safe storage, including any incompatibilities
Explosive atmospheres
Removal of dust deposits.
Only vacuum cleaners containing no ignition sources may be used for combustible dusts.
Flammability hazards
Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking.
Take precautionary measures against static discharge.
Ground/bond container and receiving equipment.

Exposure controls / personal protection

Control parameters
Occupational exposure limit values (Workplace Exposure Limits)
Country Name of agent CAS No Identifier TWA[ppm] TWA[mg/m³] STEL[ppm] STEL[mg/m³] Notation Source
GB dust WEL 10 i EH40/2005
GB dust WEL 4 r EH40/2005
Notation
i inhalable fraction
r respirable fraction
STEL short-term exposure limit: a limit value above which exposure should not occur and which is related to a 15-
minute period (unless otherwise specified)
TWA time-weighted average (long-term exposure limit): measured or calculated in relation to a reference period of
8 hours time-weighted average (unless otherwise specified)

Exposure controls
Appropriate engineering controls
General ventilation.
Individual protection measures (personal protective equipment)
Eye/face protection
Wear eye/face protection.
Hand protection
these information are not available
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.
