Guidance on Safe Use

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

Suitable extinguishing media : Water spray, Alcohol resistant foam, BC-powder, Carbon dioxide (CO2)
Unsuitable extinguishing media : Water jet
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
Advice for firefighters : In case of fire and/or explosion do not breathe fumes. Co-ordinate firefighting measures to the fire surroundings. Do not allowfirefighting water to enter drains or water courses. Collect contaminated firefighting water separately. Fight fire with normal pre cautions from a reasonable distance.

Accidental release measures

For non-emergency personnel : Remove persons to safety.
For emergency responders : Wear breathing apparatus if exposed to vapours/dust/spray/gases.
Environmental precautions : Keep away from drains, surface and ground water. Retain contaminated washing water and dispose of it.
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

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 electric al/
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.
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.

Exposure controls / personal protection

Appropriate engineering controls : General ventilation.
Individual protection measures (personal protective equipment) :
Eye/face protection : Wear eye/face protection
hand protection : Wear suitable gloves. Chemical protection gloves are suitable, which are tested according to EN 374. Check leaktightness/ impermeability prior to use. In the case of wanting to use the gloves again, clean them before taking off and air them well. For special purposes, it is recommended to check the resistance to chemicals of the protective gloves mentioned above to gether with the supplier of these gloves.
other protection measures : For special purposes, it is recommended to check the resistance to chemicals of the protective gloves mentioned above together
with the supplier of these gloves. In the case of wanting to use the gloves again, clean them before taking off and air them well. Take recovery periods for skin regeneration. Preventive skin protection (barrier creams/ointments) is recommended. Wash
hands thoroughly after handling.
Respiratory protection : In case of inadequate ventilation wear respiratory protection.
Environmental exposure controls : Use appropriate container to avoid environmental contamination. Keep away from drains, surface and ground water.

Stability and reactivity

Reactivity : Concerning incompatibility: see below "Conditions to avoid" and "Incompatible materials". It's a reactive substance. The mixture contains reactive substance(s). Risk of ignition.
If heated: Risk of ignition
Chemical stability : Conditions to avoid : Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking.
Hints to prevent fire or explosion :Use explosion-proof electrical/ventilating/lighting equipment. Use only non-sparking tools. Take precautionary measures against static discharge.
Incompatible materials : Oxidisers

Disposal considerations

Waste treatment methods :
Waste treatment-relevant information : Solvent reclamation/regeneration.
Sewage disposal-relevant information : Do not empty into drains. Avoid release to the environment. Refer to special instructions/safety data sheets.
Waste treatment of containers/packagings : It is a dangerous waste; only packagings which are approved (e.g. acc. to ADR) may be used. Completely emptied packages
can be recycled. Handle contaminated packages in the same way as the substance itself.
