First-aid measures

4.1. Description of first aid measures

General advice:

First aider needs to protect himself. Take off all contaminated clothing immediately. Medical treatment is necessary if symptoms occur which are obviously caused by skin or eye contact with the product or by inhalation of its vapours.

Inhalation:

Move subject to fresh air and keep him calm. See a physician.

Skin contact:

Wash off immediately with soap and water. If skin irritation occurs consult a physician.

Eye contact:

Flush eyes thoroughly with a large amount of water and consult a physician.

Ingestion:

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:

water spray, foam, dry chemical, carbon dioxide

Extinguishing media which must not be used for safety reasons

full 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)

no
