Eye contact:
Flush eyes thoroughly with a large amount of water and consult a physician.
Do not induce vomiting. Call a physician immediately.
4.2. Most important symptoms and effects, both acute and delayed
sensitising effects, irritant effects, Eye irritation, coughing
4.3. Indication of any immediate medical attention and special treatment needed
Treat symptomatically.

Fire-fighting measures

5.1. Extinguishing media
Suitable extinguishing media:
dry chemical
carbon dioxide
water spray
Unsuitable extinguishing media:
High volume water jet
5.2. Special hazards arising from the substance or mixture
May be released in case of fire: carbon monoxide, carbon dioxide, organic products of decomposition.
5.3. Advice for firefighters
Wear self-contained breathing apparatus.

Accidental release measures

6.1. Personal precautions, protective equipment and emergency procedures
Assure sufficient ventilation.
Wear protective gloves/protective clothing/eye protection/face protection.
Keep away sources of ignition.
Use breathing apparatus if exposed to vapours/dust/mist/aerosol.
Do not breathe vapours or spray mist.
Do not eat, drink or smoke when using this product.
Wash hands thoroughly with soap and water after handling.
6.2. Environmental precautions
Prevent product from getting into drains/surface water/groundwater.
6.3. Methods and material for containment and cleaning up
Larger quantities: Take up mechanically (by pumping).
Smaller quantities and/or residues:
Contain with absorbent material (e.g. sand, diatomaceous earth, acid absorbent, universal absorbent or sawdust).
Dispose of in accordance with regulations.
6.4. Reference to other sections
For personal protection see section 8.

Handling and storage

7.1. Precautions for safe handling
Safe handling advice:
Keep container tightly closed. Ensure there is good room ventilation.
Advice on protection against fire and explosion:
Keep away from sources of ignition --- No smoking. In the event of fire, cool the endangered containers with water. When heated above the flash point and/or during spraying (atomizing), ignitible mixtures may form in air. Take precautionary measures against static discharges.
7.2. Conditions for safe storage, including any incompatibilities
Requirements for storage areas and containers:
Protect from the action of light. Fill the container by approximately 90 % only as oxygen (air) is required for stabilisation. With large storage containers make sure the oxygen (air) supply is sufficient to ensure stability. Keep only in the original container at a temperature not exceeding 30 °C.
7.3. Specific end use(s)
