First-aid measures
4.1 Description of first aid measures General advice : Immediate medical attention is required. Move out of dangerous area. Show this safety data sheet to the doctor in attendance.
If inhaled : If breathed in, move person into fresh air. Consult a physician after significant exposure.
In case of skin contact : Take off contaminated clothing and shoes immediately. Rinse immediately with plenty of water. Immediate medical treatment is necessary as untreated wounds from corrosion of the skin heal slowly and with difficulty.
In case of eye contact : Rinse with plenty of water. Get medical attention immediately. Continue to rinse during transport. Remove contact lenses. Protect unharmed eye. Keep eye wide open while rinsing. Small amounts splashed into eyes can cause irreversible tissue damage and blindness.
If swallowed : Clean mouth with water and drink afterwards plenty of water.
Never give anything by mouth to an unconscious person. Take victim immediately to hospital. Do not induce vomiting! May cause chemical burns in mouth and throat.
4.2 Most important symptoms and effects, both acute and delayed Symptoms : The symptoms and effects are as expected from the hazards as shown in section 2. No specific product related symptoms are known.
Risks : Causes serious eye damage. Causes severe burns.
4.3 Indication of any immediate medical attention and special treatment needed Treatment : Treat symptomatically.
Fire-fighting measures
5.1 Extinguishing media Suitable extinguishing media : In case of fire: Use vermiculite, dry chemical powder or dry sand to extinguish.
Unsuitable extinguishing media
: Water Foam Carbon dioxide (CO2)
5.2 Special hazards arising from the substance or mixture Specific hazards during firefighting / Specific hazards arising from the chemical : CAUTION: reignition may occur. Waterspray may only be used by experienced fire fighters. Do not allow run-off from fire fighting to enter drains or water courses.
Combustion products : Fire will produce smoke containing hazardous combustion products (see section 10).
5.3 Advice for firefighters Special protective equipment for firefighters
: Wear self-contained breathing apparatus and protective suit.
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. After fire has been extinguished or has been allowed to burn out completely, wait CONSIDERABLE TIME (until smoke is no longer observed).
Accidental release measures
6.1 Personal precautions, protective equipment and emergency procedures Personal precautions
: Use personal protective equipment. Wear respiratory protection. Ensure adequate ventilation.
Ignition will occur. Allow controlled hydrolysis. Stop leak if safe to do so. Beware of vapours accumulating to form explosive concentrations. Vapours can accumulate in low areas.
Emergency measures on accidental release
: Evacuate personnel to safe areas. Only qualified personnel equipped with suitable protective equipment may intervene. Prevent unauthorised persons entering the zone.
6.2 Environmental precautions Environmental precautions : Prevent product from entering drains. If the product contaminates rivers and lakes or drains inform respective authorities.
6.3 Methods and materials for containment and cleaning up Methods for cleaning up / Methods for containment : Contain spillage, and then collect with non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite) and place in container for disposal according to local / national regulations (see section 13). Ensure that the product is completely non-reactive before cleaning up.
6.4 Reference to other sections For disposal considerations see section 13. For personal protection see section 8.
Handling and storage
7.1 Precautions for safe handling Advice on safe handling : For personal protection see section 8. Avoid formation of aerosol. Do not breathe vapours or spray mist. Smoking, eating and drinking should be prohibited in the application area. Dispose of rinse water in accordance with local and national regulations. Handle and open container with care.
Advice on protection against fire and explosion
: Keep away from sources of ignition - No smoking. No sparking tools should be used. Do not cut or weld on or near this container even when empty.
7.2 Conditions for safe storage, including any incompatibilities Requirements for storage areas and containers : No smoking. Keep container tightly closed and in a well-ventilated place. Electrical installations / working materials must comply with the technological safety standards. Keep under nitrogen.
Advice on common storage : Never allow product to get in contact with water during storage.
Other data : No decomposition if stored and applied as directed.
7.3 Specific end use(s) Specific use(s) : Consult the technical guidelines for the use of this substance/mixture.
