First-aid measures

4.1. Description of first aid measures
General advice
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.
Move subject to fresh air and keep him calm. In case of discomfort: Supply with medical care.
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.
Call a physician immediately.
4.2. Most important symptoms and effects, both acute and delayed
None known
4.3. Indication of any immediate medical attention and special treatment needed
None known

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
Closed container may rupture if strongly heated. 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 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. Take precautionary measures against static discharges. 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. Vapours are heavier than air and may spread along floors.
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)

8.2. Exposure controls
For monitoring procedures refer for instance to "Empfohlene Analysenverfahren für Arbeitsplatzmessungen", Schriftenreihe der Bundesanstalt für Arbeitsschutz and "NIOSH Manual of Analytical Methods", National Institute for Occupational Safety and Health
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 ca. 60 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 evolution may occur in the presence of radical forming substances (e.g. peroxides), reducing substances, and/or heavy metal ions.
10.4. Conditions to avoid
High temperature.
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
Reducing agents. Tertiary amines. Heavy metals. peroxides 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
waste from the manufacture, formulation, supply and use (MFSU) of plastics, synthetic rubber and man-made fibres - other still bottoms and reaction residues
Always check the given waste codes according to the actual conditions of manufacturing, formulation or use in your facilities.
