First-aid measures

4.1. Description of first aid measures

General advice

First aider needs to protect himself. 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.Remove contaminated, soaked clothing.


Move subject to fresh air and keep him calm. In case of discomfort: Supply with medical care.

Skin contact

Wash off with water and soap. Consult a physician if irritation persists.

Eye contact

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


Do not induce vomiting. Seek medical advice.

4.2. Most important symptoms and effects, both acute and delayed

sensitising effects

4.3. Indication of any immediate medical attention and special treatment needed

Treat symptomatically.

Fire-fighting measures

5.1. Extinguishing media

Suitable extinguishing media

foam, dry chemical, carbon dioxide

Extinguishing media which must not be used for safety reasons

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. Use personal protective clothing. 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

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. Take precautionary measures against static discharges. Use explosion-proof equipment. 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.

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. Can polymerize with intense heat release.

7.3. Specific end use(s)

Protective measures

Do not breathe vapours. Avoid contact with eyes and skin. Do not eat, drink or smoke during use.

Hygiene measures

Store work clothing separately. Take off all contaminated clothing immediately. Follow the usual good standards of occupational hygiene. Clean skin thoroughly after work; apply skin cream.

Respiratory protection

Breathing apparatus in case of high concentrations, short term: filter appliance, filter A

Hand protection

butyl rubber gloves (0.3 mm), Break through time 480 min (EN 374)

In practice, due to variable exposure conditions, this information can only be an aid to orientation for the selection of a suitable chemical protection glove. In particular, this information does not substitute suitability tests by the end user.

General information

Gloves should be replaced regularly, especially after extended contact with the product. For each work-place a suitable glove type has to be selected.

Eye protection

tightly fitting goggles

Skin and body protection

On handling of larger quantities: face mask, chemical-resistant boots and apron

Stability and reactivity

10.1. Reactivity

see section 10.2.

10.2. Chemical stability

No decomposition if used as directed.

10.3. Possibility of hazardous reactions

Polymerization with heat formation and a risk of spontaneous ignition are possible in the presence of radical formers (e.g. peroxides) reducing substances and/or heavy metals.

10.4. Conditions to avoid

This material is considered stable.Protect from the action of light.

The product is normally supplied in a stabilized form. If the permissible storage period and/or storage temperature is exceeded, the product may polymerize with heat evolution.

10.5. Incompatible materials

Peroxides, amines, sulfur compounds, heavy metal ions, alkalis, reducing agents and oxidizing agents. Mineral acids. Free radical initiators.

10.6. Hazardous decomposition products

None when used as directed.

Disposal considerations

13.1. Waste treatment methods


Waste is hazardous. It must be disposed of in accordance with the regulations after consultation of the competent local authorities and the disposal company in a suitable and licensed facility.

Uncleaned packaging

Contaminated packaging should ideally be emptied; it can then be recycled after having been decontaminated. Packaging that cannot be cleaned should be disposed of professionally. Uncontaminated packaging may be taken for recycling.

Code of waste EWC

07 02 08
