First-aid measures
General information:
Take persons to a safe place. Observe self-protection for first aid. Always seek medical advice
in the event of contact with this substance.
After inhalation
Keep the patient calm. If unconscious place in stable sideways position. Protect against loss
of body heat. If breathing stops, administer artificial respiration. Seek medical advice
immediately and clearly identify substance.
After contact with the skin
Remove contaminated clothes at once. Wash off with plenty of water or water and soap
immediately for 10-15 minutes. In serious cases, use emergency shower immediately. Seek medical
advice immediately and clearly identify substance.
After contact with the eyes
Rinse immediately with plenty of water for 10-15 minutes. Keep eyelids well open to rinse the
whole eye surface and eyelids with water. Seek medical advice immediately and clearly identify
substance. Continue to bathe eyes during transport to medical practitioner.
After swallowing
If conscious, give several small portions of water to drink. Do not induce vomiting. Seek
medical advice immediately and clearly identify substance.
Advice for the physician
After inhalation: treat as early as possible using cortisone spray. Medical checks necessary up
to a latency period of at least 24 hours. In the event of 1st degree burns use corticoidexterna.
In the case of 2nd degree burns, use symptomatic treatment. Risk of intra-abdominal
gas developing if swallowed. Risk of perforation of the stomach.

Fire-fighting measures
Suitable extinguishing media
alcohol-resistant foam , carbon dioxide , dry sand . Application of foam will release at least
initially significant amounts of flammable and corrosive vapors. These vapors could be trapped
under the foam blanket.
Extinguishing media which must not be used for safety reasons
water , extinguishing powder , halones .
Special exposure hazards arising from the substance or preparation itself, combustion products,
resulting gases
Hazardous combustion 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. If material is released indicate risk of slipping.
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.
Further information:
Eliminate all sources of ignition.

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. Spilled substance increases risk of slipping.
Precautions against fire and explosion:
Flammable vapors may accumulate and form explosive mixtures with air in containers, process
vessels, including partial, empty and uncleaned containers and vessels, or other enclosed
spaces. Vapours heavier than air, therefore inflammable gas mixture may form mainly near floor.
Keep away from sources of ignition and do not smoke. Take precautionary measures against
electrostatic charging. 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.

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.
