First-aid measures

1. Description of first aid measures
General notes
Do not leave affected person unattended. Remove victim out of the danger area. Keep affected person warm, still and covered.
Take off immediately all contaminated clothing. In all cases of doubt, or when symptoms persist, seek medical advice. In case
of unconsciousness place person in the recovery position. Never give anything by mouth.
Following inhalation
If breathing is irregular or stopped, immediately seek medical assistance and start first aid actions. In case of respiratory tract irritation,
consult a physician. Provide fresh air.
Following skin contact
Wash with plenty of soap and water.
Following eye contact
Remove contact lenses, if present and easy to do. Continue rinsing. Irrigate copiously with clean, fresh water for at least 10
minutes, holding the eyelids apart.
Following ingestion
Rinse mouth with water (only if the person is conscious). Do NOT induce vomiting.

Fire-fighting measures

1. Extinguishing media
Suitable extinguishing media
Foam, Water spray, Dry extinguishing powder
Unsuitable extinguishing media
Water jet

2. Special hazards arising from the substance or mixture
In case of insufficient ventilation and/or in use, may form flammable/explosive vapour-air mixture. Solvent vapours are heavier
than air and may spread along floors. Places which are not ventilated, e.g. unventilated below ground level areas such as
trenches, conduits and shafts, are particularly prone to the presence of flammable substances or mixtures. The exposure of containers
to heat leads to an increase in pressure with a risk of bursting and subsequent explosion. Develops toxic and irritant vapours
during strong heating or fire.
Hazardous combustion products
Nitrous gases, Carbon monoxide (CO), Carbon dioxide (CO2), Siliconoxides

3. Advice for firefighters
In case of fire and/or explosion do not breathe fumes. Co-ordinate firefighting measures to the fire surroundings. Do not allow
firefighting water to enter drains or water courses. Collect contaminated firefighting water separately. Fight fire with normal precautions
from a reasonable distance. Keep containers cool with water spray. Precipitate combustion gases with water spray if
possible.

Accidental release measures

1. Personal precautions, protective equipment and emergency procedures
For non-emergency personnel
Remove persons to safety.
For emergency responders
Wear breathing apparatus if exposed to vapours/dust/spray/gases.

2. Environmental precautions
Keep away from drains, surface and ground water. Retain contaminated washing water and dispose of it.

3. Methods and material for containment and cleaning up
Advices on how to contain a spill
Covering of drains
Advices on how to clean up a spill
Wipe up with absorbent material (e.g. cloth, fleece). Collect spillage: sawdust, kieselgur (diatomite), sand, universal binder
Appropriate containment techniques
Use of adsorbent materials.
Other information relating to spills and releases
Place in appropriate containers for disposal. Ventilate affected area.

Handling and storage

This substance is handled under Strictly Controlled Conditions in accordance with REACH regulation Article 18(4) for transported isolated intermediates. Site documentation to support safe handling arrangements including the selection of engineering, administrative and personal protective equipment controls in accordance with risk-based management systems is available at each Manufacturing site. Written confirmation of application of Strictly Controlled Conditions has been received from affected Distributor and Downstream Manufacturer/User of the Registrant's intermediate.

1. Precautions for safe handling
Recommendations
- measures to prevent fire as well as aerosol and dust generation
Use local and general ventilation. Avoidance of ignition sources. Keep away from sources of ignition - No smoking. Take precautionary
measures against static discharge. Use only in well-ventilated areas. Due to danger of explosion, prevent leakage of
vapours into cellars, flues and ditches. Ground/bond container and receiving equipment. Use explosion-proof electrical/ventilating/
lighting/equipment. Use only non-sparking tools.
- specific notes/details
Places which are not ventilated, e.g. unventilated below ground level areas such as trenches, conduits and shafts, are particularly
prone to the presence of flammable substances or mixtures. Vapours are heavier than air, spread along floors and form explosive
mixtures with air. Vapours may form explosive mixtures with air.
Advice on general occupational hygiene
Wash hands after use. Do not eat, drink and smoke in work areas. Remove contaminated clothing and protective equipment before
entering eating areas. Never keep food or drink in the vicinity of chemicals. Never place chemicals in containers that are
normally used for food or drink. Keep away from food, drink and animal feedingstuffs.

2. Conditions for safe storage, including any incompatibilities
Managing of associated risks
- explosive atmospheres
Keep container tightly closed and in a well-ventilated place. Use local and general ventilation. Keep cool. Protect from sunlight.
Protect from moisture.
- flammability hazards
Keep away from sources of ignition - No smoking. Keep away from heat, hot surfaces, sparks, open flames and other ignition
sources. No smoking. Take precautionary measures against static discharge. Protect from sunlight.
- packaging compatibilities
Only packagings which are approved (e.g. acc. to ADR) may be used.
- ventilation requirements
Use local and general ventilation. Ground/bond container and receiving equipment.
- packaging compatibilities
Only packagings which are approved (e.g. acc. to ADR) may be used.
