Antidote: Hydroxycobalamine (vitamine B12, Cyanokit (R)).
Artificial respiration with 100% oxygen.
Symptomatic treatment.

Fire-fighting measures

Extinguishing media
Suitable extinguishing agents: CO₂, powder or water spray. Fight larger fires with water spray or
alcohol resistant foam.
For safety reasons unsuitable
extinguishing agents: No restriction in large fires.

Special hazards arising from the
substance or mixture: In case of fire, the following can be released:
Nitrogen oxides (NOx)
Carbon monoxide (CO)
A dust explosion may occur caused by electrostatic discharge.

Advice for firefighters
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.

Accidental release measures

Personal precautions, protective equipment and emergency procedures
Avoid contact with eyes and skin.
Wear protective clothing.
Use respiratory protective device against the effects of fumes/dust/
aerosol.
Avoid formation of dust.

Environmental precautions: Keep contaminated washing water and dispose of appropriately.
Do not allow undiluted product or large quantities of it to reach
ground water, water course or sewage system.

Methods and material for containment
and cleaning up: Dispose contaminated material as waste according to item 13.
Pick up mechanically. If formation of dust cannot be avoided use
respiratory filter device.
Put damaged containers into recovery drums.

Discharge into waste water channels and biological treatment plants
only after clearance with the operating company and in accordance
with local Authority approval.

Handling and storage

Precautions for safe handling: Nitrogen blanketing required for large scale operations with this
compound due to low minimum ignition energy.
Any unavoidable deposit of dust must be completely removed.
Fill only in dedicated and assigned containers.
Keep containers tightly sealed.
Information about fire - and explosion
protection: Electrostatic charging may occur.

Conditions for safe storage, including any incompatibilities:
Storage
Requirements to be met by storerooms
and receptacles: Store in a dry location, keep away from humidity.
Corrosion of metals: Test method according to CLP is not applicable (solid material at 55
°C).
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: No data available.
Recommended storage temperature: Currently no data available.
It is therefore recommended not to exceed room temperature (max.
25 °C) during storage over a longer period of time.
Acceptable storage time: No data available.
