Following skin contact: Immediately wipe affected skin area with paper towel or cloth.

Immediately clean with water and soap followed by thorough rinsing.

In case of skin irritation, consult a physician.

After eye contact: Immediately flush eyes with plenty of flowing water for 10 to 15 minutes holding eyelids

apart. In case of troubles or persistent symptoms, consult an opthalmologist.

After swallowing: Rinse mouth with water.

Never give an unconscious person anything through the mouth.

Consult physician immediately.

Most important symptoms and effects, both acute and delayed:

After contact with skin: sensitising

Indication of any immediate medical attention and special treatment needed:

Treat symptomatically.

Fire-fighting measures

Extinguishing media:

Suitable extinguishing media:

Foam, extinguishing powder, Carbon dioxide.

Extinguishing media which must not be used for safety reasons:

High power water jet

Special hazards arising from the substance or mixture:

Combustible. In case of fire may be liberated: silicon dioxide, traces of incompletely

burned carbon compounds, carbon monoxide and carbon dioxide.

Advice for firefighters:

Special protective equipment for firefighters:

Wear self-contained breathing apparatus and protective clothing to protect skin and eyes.

Additional information: Hazchem-Code: -

Cool endangered containers with water jetspray.

Do not allow water used to extinguish fire to enter drains, ground or waterways.

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Remove all sources of ignition. Wear suitable protective clothing.

Avoid contact with skin, eyes, and clothing.

Do not breathe vapour/aerosol. Provide adequate ventilation.

Environmental precautions:

Do not allow to penetrate into soil, waterbodies or drains.

Methods and material for containment and cleaning up:

Soak up with absorbent materials such as sand, siliceus earth, acid- or universal binder.

Store in special closed containers and dispose of according to ordinance. Final cleaning.

See paragraphs Exposure controls/ personal protections and Disposal considerations for further information.

Handling and storage

Precautions for safe handling:

Advices on safe handling: Avoid contact with skin, eyes, and clothing. Wear suitable protective clothing.

Do not breathe vapour/aerosol. Provide for good room ventilation, suctioning/venting.

Conditions for safe storage, including any incompatibilities:

Requirements for storerooms and containers:

Keep container tightly closed in a cool, well-ventilated place.
