First-aid measures

Description of first aid measures

1. 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.

2. Most important symptoms and effects, both acute and delayed: Symptoms and effects are not known to date.

3. Indication of any immediate medical attention and special treatment needed: none

Fire-fighting measures

1. Extinguishing media
Suitable extinguishing media: Water spray, Alcohol resistant foam, BC-powder, Carbon dioxide (CO2)
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.

Hazardous combustion products: Nitrogen oxides (NOx), 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.

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 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, 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.

materials: see section "Stability and reactivity". Disposal considerations: see section "Disposal considerations".

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.
- 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.
- 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.
