Fire-fighting measures

Extinguishing media
Suitable extinguishing agents: Water haze
Alcohol resistant foam
Fire-extinguishing powder
Carbon dioxide
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:
Carbon monoxide (CO)

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
Wear protective clothing.
Use respiratory protective device against the effects of fumes/dust/
aerosol.

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: Absorb with liquid-binding material (sand, diatomite, acid binders,
universal binders, sawdust).
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: Inert gas blanketing required.
Fill only in dedicated and assigned containers.
Keep containers tightly sealed.
Information about fire - and explosion
protection: No special measures required.

Conditions for safe storage, including any incompatibilities:
Storage
Requirements to be met by storerooms and
receptacles: Storage under inert gas.
Store in a cool location.
Use only receptacles specifically permitted for this substance/product.
Corrosion of metals: No corroding action on metals (expert statement).
Information about storage in one common
storage facility: Store away from oxidising agents.
Further information about storage
conditions: Avoid contact with air / oxygen.
Store under inert gas.

Exposure controls / personal protection

Control parameters
Additional information about design of
technical facilities: Check seals on flanges and valves for suitability and corrosion
resistance.
If necessary inspection intervals should be defined!
Ingredients with limit values that require monitoring at the workplace:
DNEL/PNEC-values: According to Art. 17 and 18 of EU-Regulation 1907/2006 (REACH) this
substance is used as isolated intermediate under strictly controlled
conditions. Therefore no DNEL/PNEC is required.
PNEC-values:
AEGL: Not listed.
IDLH: Not listed

TEEL: Not listed.

Exposure controls: This product is exclusively dedicated for the application as isolated and
transported intermediate under strictly controlled conditions according
to Article 18 of Regulation EC 1907/2006 (REACH-Regulation).
Personal protective equipment
General protective and hygienic measures: The usual precautionary measures are to be adhered to when handling
chemicals.
Respiratory protection: In case of brief exposure or low pollution use respiratory
filter device. In case of intensive or longer exposure use
self-contained respiratory protective device.
Filter A.
Protection of hands: Selection of the glove material on consideration of the penetration
times, rates of diffusion and the degradation.
For the permanent contact gloves made of
the following materials are suitable: Currently no information available about suitable materials for safety
gloves.
Check for tightness before use.
Replace damaged gloves.
Eye protection:
Safety glasses
Body protection: Use only liquid proof and chemical resistant protective suit.
Protection against thermal hazards: No specific measures required.
Limitation and supervision of exposure into
the environment: Avoid spillage of product into the environment.
If possible use this material only in closed systems and devices. In case
of open plant systems (sampling devices, filling and discharging,
cleansing works etc.) use local exhaust and collecting trays. Follow
emission limit values. Measures in case of unwanted emissions should
be established.
Risk management measures: General protective and hygienic measures have to be observed.
Handling and use of this material/formulation only under controlled
conditions in closed systems.
Employees who use this material/formulation must be trained and
demonstrably instructed about possible risks for man and environment.
Measures for prevention of hazards in case of unwanted leakage
shall be implemented.
