First-aid measures
• After inhalation: If metal vapours or solid dusts have been inhaled:
Get the affected person out in the fresh air and call a doctor.
• After skin contact: Foreign bodies which have penetrated the skin must be removed
and the wound cleaned thoroughly.
Remove contaminated clothing.
If skin irritation continues, consult a doctor.
• After eye contact: Foreign bodies must be removed, consult a doctor if necessary.

combination 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 regulation
on 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.
• Ingredients with limit values that require monitoring at the workplace:
7440-48-4 cobalt
ERB (Germany) 0.5 μg/m³ (A) bzw. 5μg/m³ (A)
MAK (Germany) inhalable fraction; see Abschn.XIII
• DNELs
DNELs for OSH purposesIn
Germany, occupational exposure limits (AGW) of the Technical Rules on
Hazardous Substances (TRGS) 900 continue to constitute workplace atmospheric limit values thatare binding upon employers. Should no AGW and for example no maximum workplace concentration (MAK value) of the German Research Foundation (DFG) be available, the employer must also
consider the DNEL during risk assessment.(Source: Institut für Arbeitsschutz der Deutschen Gesetzlichen Unfallversicherung (IFA))current values are available: http://www.dguv.de/ifa/gestis/gestis-dnelliste/index.jsp.

Recommendation: P3
• Protection of hands: Avoid repeated and prolonged contact with the skin, use
protective gloves.
Preventive skin protection by use of skin-protecting
agents is recommended.

• Eye protection:
Tightly sealed goggles (EN 166)
• Limitation and supervision of
exposure into the environment The legal issue values and limitations are to be paid attention!

Stability and reactivity
• Thermal decomposition /
conditions to be avoided: It 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.
