First-aid measures

Inhalation: If metal vapours or solid dusts have been inhaled: Get the affected person out in the fresh air and call a doctor.

Skin contact: Foreign bodies which have penetrated the skin must be removedand the wound cleaned thoroughly. Remove contaminated clothing. If skin irritation continues, consult a doctor.

Eye contact: Foreign bodies must be removed, consult a doctor if necessary.

Ingestion: Rinse mouth and drink plenty of water. Cause vomiting and ensure a doctor is consulted.

Fire-fighting measures

Suitable extinguishing agents: Dry sand, metal fire powder or carbon powder.

For safety reasons unsuitable extinguishing agents: Water and Carbon dioxide

Special hazards caused by the substance, its products ofcombustion or resulting gases: Can form explosive gas-air mixtures.

Advice for fire fighters: Protective equipment: Wear self-contained respiratory protective device.

Accidental release measures

Person-related safety precautions: Use respiratory protective device against the effects of fumes/dust/aerosol.

Measures for environmental protection: Do not allow product to reach sewage system or any water course.

Measures for cleaning/collecting: Do not flush with water or aqueous cleansing agents. When cold, sweep it up carefully. Avoid dust development.

Handling and storage


Information for safe handling: Keep receptacles tightly sealed. Prevent formation of dust. Fill only in inert gas. Ensure good ventilation/exhaustion at the workplace. Take note of emission threshold.

Information about fire - and explosion protection: Keep ignition sources away - Do not smoke. Protect against electrostatic charges. Inflammable and explosive dust-air mixtures can develop incombination with air.

Storage: Requirements to be met by storerooms and receptacles: Containers must be clearly and indelibly identified. Information about storage in one common storage facility: Store away from foodstuffs.

Further information about storage conditions: Store in cool, dry conditions in well sealed receptacles.

Storage class: Comply with on-site storage guidelines for substances able to heat up spontaneously (pyrophoric).

Class according to regulationon flammable liquids: Not applicable

Exposure controls / personal protection

Additional information about design of technical facilities: Provide a suitable suction with filter and good ventilation of the working area for all processing steps. Suitable breathing apparatus must be used (see personal safety equipment) for repair and maintenance work on suction systems, especially when changing the filters.

Compliance with the general dust limit value(s) (lung penetratingand/or inhalable fraction) must be ensured.

Personal protective equipment: General protective and hygienic measures: Keep away from foodstuffs, beverages and feed. Wash hands before breaks and at the end of work.

Respiratory protection: In the case of dust formation (limit value exceeded),breathing apparatus must be worn.Time limits for wearing must be observed. Breathing mask, apparatus with particle filter P2 or P3,for example:- Full face mask (EN 136)- Breathing mask (EN 149) FFP2 or FFP310 times the limit value (FFP2)30 times the limit value (FFP3) Recommendation: P3

Protection of hands: Avoid repeated and prolonged contact with the skin, useprotective gloves. Preventive skin protection by use of skin-protecting agents is recommended. Material of gloves: Material of gloves should be impenetrable (e.g. nitrile caoutchouc). Depending on use heat protective gloves are required. Penetration time of glovematerial -

Eye protection: Tightly sealed goggles (EN 166)

Stability and reactivity

Thermal decomposition /conditions to be avoided: Does not degrade if properly used with a protective gas (argon). Attention: At high temperatures the substance has an exothermic reaction in combination with nitrogen.

Materials to be avoided: Aqueous media (e.g. acid, alkaline solutions, water), substances with an oxidizing effect.

Dangerous reactions: Hydrogen is released when it comes into contact with water, and explosive gaseous mixtures can develop. In combination with air or atmospheres with an oxidizing effect fine powders can develop spontaneous heating or become pyrophoric.

Dangerous decomposition products: No dangerous decomposition products known.

Disposal considerations

Observe offical regulations.

Uncleaned packaging: Recommendation: Empty contaminated packagings thoroughly. They may be recycled after thorough and proper cleaning. Packaging that may not be cleansed are to be disposed of in the same manner as the product.
