Guidance on Safe Use

First-aid measures

Description of first aid measures

General information:

Remove contaminated clothes at once. In case of accident or if you feel unwell seek medical advice immediately (show the label if

possible). Observe self-protection for first aid. Take persons to a safe place. Keep warm, in restful position, cover up.

After inhalation:

Move to fresh air, keep the victim laying down and restful. If breathing has stopped, give artificial respiration. Administer oxygen in

case of breathing difficulties. Seek medical advice and clearly identify substance.

After contact with the skin:

Wash immediately with plenty of water. Remove contaminated clothes at once. In serious cases, use emergency shower

immediately. Seek medical advice and clearly identify substance. Do not use ointments or plasters unless recommended by

medical practitioner. Do not take clothing home for washing.

After contact with the eyes:

Rinse immediately with plenty of water for 10-15 minutes and seek medical advice. Keep eyelids well open to rinse the whole eye

surface and eyelids with water. Continue to bathe eyes during transport to medical practitioner.

After swallowing:

Rinse mouth with water. If conscious, give several small portions of water to drink. Do not induce vomiting. Seek medical advice

immediately and produce the label or packaging. Never give an unconscious person anything by mouth!

Most important symptoms and effects, both acute and delayed

Any relevant information can be found in other parts of this section.

Indication of any immediate medical attention and special treatment needed

Symptomatic treatment.

Fire-fighting measures

Extinguishing media

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 hazards arising from the substance or mixture

Hazardous combustion products: hydrogen chloride , highly toxic gases .

Advice for firefighters

Special protective equipment for fire fighting:

Use respiratory protection independent of recirculated air. Use tightly fitting chemical protection suit (see section Exposure controls/personal protection).

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Wear personal protection equipment (see section Exposure controls/personal protection). Task force: Use tightly fitting chemical protection suit (see section Exposure controls/personal protection). 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 and material for containment and 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.

Reference to other sections

Relevant information in other sections have to be considered. This applies in particular for information given on personal

protective equipment (section Exposure controls/personal protection) and on disposal (section Disposal considerations).

Handling and storage

Precautions for safe handling

Precautions for safe handling:

Ensure adequate ventilation. Must be syphoned off in situ. Keep away from incompatible substances in accordance with section Stability and Reactivity. 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.

Conditions for safe storage, including any incompatibilities

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.
