Administrative data
First-aid measures
Move out of dangerous area.
Consult a physician.
Show this safety data sheet to the doctor in attendance.
Do not leave the victim unattended.
IF INHALED
Move to fresh air.
If symptoms persist, call a physician.
If unconscious, place in recovery position and get medical attention immediately.
IN CASE OF SKIN CONTACT
Immediate medical treatment is necessary as untreated wounds from corrosion of the skin heal slowly and with difficulty.
Wash contaminated clothing before reuse.
If on skin, rinse well with water.
If on clothes, remove clothes.
IN CASE OF EYE CONTACT
Small amounts splashed into eyes can cause irreversible tissue damage and blindness.
Remove contact lenses.
In the case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
Continue rinsing eyes during transport to hospital.
Protect unharmed eye.
Keep eye wide open while rinsing.
If eye irritation persists, consult a specialist.
IF SWALLOWED
Keep respiratory tract clear.
Do NOT induce vomiting.
Do not give milk or alcoholic beverages.
Never give anything by mouth to an unconscious person.
If symptoms persist, call a physician.
Take victim immediately to hospital.
SYMPTOMS
Skin contact may provoke the following symptoms: Burn, corrosive effects, Redness
Ingestion may provoke the following symptoms: Stomach/intestinal disorders
Eye contact: Excessive lachrymation
Fire-fighting measures
Water mist
Water spray jet
Foam
Carbon dioxide (CO2)
Dry chemical
UNSUITABLE EXTINGUISHING MEDIA
High volume water jet
SPECIFIC HAZARDS DURING FIREFIGHTING
Do not allow run-off from fire fighting to enter drains or water courses.
HAZARDOUS COMBUSTION PRODUCTS
Metal oxides
SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS
Wear self-contained breathing apparatus for firefighting if necessary.
FURTHER INFORMATION
Collect contaminated fire extinguishing water separately. This must not be discharged into drains.
Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations.
Accidental release measures
Use personal protective equipment.
Avoid dust formation.
Avoid breathing dust.
ENVIRONMENTAL PRECAUTIONS
Prevent product from entering drains.
Prevent further leakage or spillage if safe to do so.
If the product contaminates rivers and lakes or drains inform respective authorities.
METHODS FOR CLEANING UP
Neutralise with acid.
Keep in suitable, closed containers for disposal.
Handling and storage
Avoid formation of respirable particles.
Do not breathe vapours/dust.
Avoid contact with skin and eyes.
Smoking, eating and drinking should be prohibited in the application area.
Dispose of rinse water in accordance with local and national regulations.
ADVICE ON PROTECTION AGAINST FIRE AND EXPLOSION
Avoid dust formation. Provide appropriate exhaust ventilation at places where dust is formed.
HYGIENE MEASURES
When using do not eat or drink. When using do not smoke. Wash hands before breaks and at the end of workday.
REQUIREMENTS FOR STORAGE AREAS AND CONTAINERS
Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully re-sealed and kept upright to prevent leakage. Observe label precautions. Electrical installations / working materials must comply with the technological safety standards. To maintain product quality, do not store in heat or direct sunlight.
OTHER DATA
Keep in a dry place. No decomposition if stored and applied as directed.
