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.

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

Symptoms and effects are not known to date.

Fire-fighting measures

1. Extinguishing media

Suitable extinguishing media

Dry extinguishing powder, Alcohol resistant foam, Carbon dioxide (CO2)

Unsuitable extinguishing media

Water jet

2. Special hazards arising from the substance or mixture

Develops corrosive and irritant vapours. Vapours are heavier than air, spread along floors and form explosive mixtures with air.

In case of insufficient ventilation and/or in use, may form flammable/explosive vapour-air mixture. 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

vapours. The exposure of containers to heat leads to an increase in pressure with a risk of bursting and subsequent explosion.

Hazardous combustion products

Carbon monoxide (CO), Carbon dioxide (CO2), Siliconoxides, Nitrous gases

3. Advice for firefighters

In case of fire and/or explosion do not breathe fumes. Wear self-contained breathing apparatus. Precipitate combustion gases

with water spray if possible. Fight fire with normal precautions from a reasonable distance. Co-ordinate firefighting measures to

the fire surroundings. Do not allow firefighting water to enter drains or water courses. Collect contaminated firefighting water

separately. Remove undamaged containers from heat radiation. Keep containers cool with water spray. Reacts violently with

water.

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

Advice on how to contain a spill

Covering of drains

Advice 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.

- 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.

- incompatible substances or mixtures

Protect from moisture.

- ventilation requirements

Keep any substance that emits harmful vapours or gases in a place that allows these to be permanently extracted. 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.

3. Specific end use(s)
