Fire-fighting measures
General information:
Product does not burn. Use extinguishing measures appropriate to the source of the fire.
Suitable extinguishing media
not applicable
Extinguishing media which must not be used for safety reasons
water .
Special exposure hazards arising from the substance or preparation itself, combustion products,
resulting gases
Hazardous decomposition products: hydrogen chloride .
Special protective equipment for fire fighting
Use respiratory protection independent of recirculated air. Use tightly fitting chemical
protection suit (see section 8).
Accidental release measures
Personal precautions
Wear personal protection equipment (see section 8). Task force: Use tightly fitting chemical
protection suit (see section 8). Keep unprotected persons away. Avoid contact with eyes and
skin. Avoid inhaling mists and vapours. Do not walk through spilled material. Ensure adequate
ventilation.
Environmental precautions
Prevent material from entering surface waters, drains or sewers and soil. Contain any fluid
that runs out using suitable material (e.g. earth). Condense gasses/vapours/mists using a
directed spray of water. Retain contaminated water/extinguishing water. Dispose of in
prescribed marked containers. For large amounts: Close leak if possible without risk.
Methods for cleaning up
Do not flush away with water. For small amounts: Absorb with liquid, mainly acid binding
material and dispose of according to local/state/federal regulation. Cover larger quantities by
near waterless foam and take up in container. Exhaust vapours. Clean up with plenty of water.
Handling and storage
Handling
Precautions for safe handling:
Ensure adequate ventilation. Must be syphoned off in situ. Keep away from incompatible
substances in accordance with section 10.2.
Precautions against fire and explosion:
Cool endangered containers with water.
Storage
Conditions for storage rooms and vessels:
Store under protective gas.
Advice for storage of incompatible materials:
not applicable
Further information for storage:
Protect against moisture. Store in original container only. Keep container tightly closed and
store in a cool, well ventilated place.

Exposure controls / personal protection
Exposure limits
-
Exposure limited and controlled
Exposure in the work place limited and controlled
General protection and hygiene measures:
Do not breathe vapours. Avoid contact with eyes and skin. Do not eat, drink or smoke when
handling. Wash hands at the end of work and before eating. Keep working clothes separately.
Personal protection equipment
Respiratory protection
gas mask filter ABEK . In case of long or strong exposure: positive pressure self contained
breathing apparatus .
Hand protection
protective gloves/ gauntlets (5-layer laminate) made of PE and EVOH (4H) or Butyl & Viton types recommended; nitrile gloves may also be used for short durations. At any sign of decay or chemical permeability
remove gloves immediately and replace. Wear gloves for short periods only < 10 mins.
Eye protection
tight fitting protective goggles . Where there is risk of splashing: protective shield .
Provide work station with eye bathing equipment. Do not wear contact lenses.
Skin protection
apron , protective clothing, face protection, neck protection , acid-proof protective clothing.
Exposure to the environment limited and controlled
Prevent material from entering surface waters, drains or sewers and soil.

General information:
Violent reactions are possible with various chemicals.
Conditions to avoid moisture .
Materials to avoid
proton-active substances . Reacts violently with: water , basic substances , acids , alcohols
and ketones/aldehydes . Reaction causes the formation of: hydrogen chloride and heat .

Disposal considerations
Material
Recommendation:
Dispose of according to regulations by incineration in a special waste incinerator. Observe
local/state/federal regulations. Ensure special chem./phys. treatment after discussion with the
supplier.
Uncleaned packaging
Recommendation:
Completely discharge containers (no tear drops, no powder rest, scraped carefully). Containers
may be recycled or re-used. Observe local/state/federal regulations. Uncleaned packaging should
be treated with the same precautions as the material.
