First-aid measures

- General advice: Persons who have come into contact with the material or have breathed in vapours should get immediate medical treatment also in case of delayed symptoms. Add all available substance related information. Immediately remove any clothing soiled by the product. In case of irregular breathing or respiratory arrest provide artificial respiration.
- Following inhalation: In case of unconsciousness place patient stably in side position for transportation.
- Following skin contact: Immediately wash with water and soap and rinse thoroughly.
- Following eye contact: Call a doctor immediately. Remove contact lenses immediately!
- Following ingestion: Rinse opened eye for several minutes under running water. Then consult a doctor. Do not induce vomiting; immediately call for medical help. Drink copious amounts of water and provide fresh air. Immediately call a doctor.

- Most important symptoms and effects: Contact with dust may cause irritation of mucous membranes.
Corrosion, cough, risk of eye damage/blindness, perforation of the stomach, difficulty in breathing, allergic reaction, Sensitization possible through skin contact. Burning of eyes, mucous membranes and skin. Coughing, headache, indisposition, shortness of breath.
- Skin: Strong irritating/corrosive action. Irritating action through sensitization.
- Eyes: Strong irritation with danger of serious damage to eyes.
- Respiratory tract: After breathing of dust possible irritation of nose, respiratory tract, lungs: Cough, shortness of breath. Strong irritating action on whole respiratory tract.
- Hazards and systemic effects: Strong irritating effect after breathing of dust and contact with eyes.
Sensitization possible through skin contact. Extremely corrosive action on mucous membranes of upper respiratory tract as well as eyes and skin. After contact with this material possibly corrosive action on skin and
mucous membranes.
- Possible routes of intake: Intake by swallowing or inhalation of dust.
- Target organs: Skin, eyes, mucous membranes. Respiratory tract
- Chronic effects: Sensitization

Fire-fighting measures

- Suitable extinguishing media: CO2, extinguishing powder or water spray. Fight larger fires with water spray or alcohol resistant foam.
- Unsuitable extinguishing media: No restriction in large fires.
- Special hazards arising from the substance or mixture: Very high danger of dust explosions. In case of fire, the following can be released: Carbon monoxide (CO)
- Advice for fire fighter:
- Protective equipment: Wear self-contained respiratory protective device. Chemical resistant protective suit. Under the protective suit a fire protective suit according to EN 469 should be applied. Use chemical protective suit and self-contained breathing apparatus while undressing contaminated co-workers or handling contaminated equipment.
- Additional information: Dispose of fire debris and contaminated firefighting water in accordance with official regulations. Collect contaminated firefighting water separately. It must not enter the sewage system.

Accidental release measures

- Personal precautions, protective equipment and emergency procedures: Wear protective clothing. Avoid contact with eyes and skin. Do not breathe dust. Access only for trained personnel with personal protective equipment. Use respiratory protective device against the effects of fumes/dust/aerosol. Avoid spillage of product into the environment. Avoid formation of dust.
- Environmental precautions: Do not allow to enter sewers/ surface or ground water. Inform respective authorities in case of seepage into water course or sewage system. Keep contaminated washing water and dispose of appropriately.
- Methods and material for containment and cleaning up: Pick up mechanically. Ensure adequate ventilation. Possible formation of explosive dust/air mixtures. Dispose contaminated material as waste according to item 13.

Handling and storage

- Precautions for safe handling: Empty containers must not be used for other products. Nitrogen blanketing required for large scale operations with this compound due to low minimum ignition energy. Contaminated protective equipment should be cleaned before taking it off. Thorough dedusting. Ensure good ventilation/exhaustion at the workplace. Fill only in dedicated and assigned containers. Keep containers tightly sealed. Information about protection against explosions and fires: Very high danger of dust explosions.
- Conditions for safe storage, including any incompatibilities:
- Requirements to be met by storerooms and receptacles: Store in a dry location, protected from humidity.
- Corrosion to metals: It should generally be borne in mind that there is a possibility of corrosion on contact with this material. Resistance should be checked in each individual case.
- Information about storage in one common storage facility: Store away from oxidizing agents.
- Further information about storage conditions: None.
- Maximum storage temperature: +8 °C
- Storage stability: No data available.

Exposure controls / personal protection

- Additional information about design of technical systems: No further data. Waste gases should be led into the atmosphere only via appropriate separators, scrubbers or incinerators.

- Components with limit values that require monitoring at the workplace: Not required.
- Recommendation of supplier: 0.16 mg/m³ 8h (ECETOC TR 101 Hazard Banding)
- General protective and hygienic measures Contaminated protective suit shall be cleaned before taking it off. Keep away from foodstuffs, beverages and feed.
