Administrative data
First-aid measures
In case of skin contact :
Immediately take off all contaminated clothing and shoes. Areas of the body that have - or are only even suspected of having - come into contact with the product must be rinsed immediately with plenty of running water and possibly with soap.
Wash thoroughly the body (shower or bath).
Immediately remove any contaminated clothing, shoes or stockings.
After contact with skin, wash immediately with soap and plenty of water.
In case of eye contact : wash immediately with water
In case of ingestion : give nothing to eat or drink
In case of inhalation : Remove casualty to fresh air and keep warm and at rest.
Indication of any immediate medical attention and special teatment needed
In case of accident or unwellness, seek medical advice immediately (show directions for use or safety data sheet of possible).
Fire-fighting measures
Extinguishing media :
Water, CO2, foam, chemical powders, according to the materials involved in the fire. In case of fire, use foam, dry chemical, CO2.
Unsuitable extinguiishing media : None in particular
Special hazards arising from the substance or mixture
Do not inhale explosion and combustion gases.
Burning produces heavy smoke.
Advice for fire-fighters : Use suitable breathing apparatus. Collect contaminated fire extinguishing water separately. This must not be discharged into drains
Accidental release measures
Personal precautions, protective equipment and emergency procedure : Wear personal protection equipment. Remove persons to safety.
Environmental precautions : Do not allow to enter into soil/subsoil. Do not allow to enter into surface water or drains. Retain contaminated washing water and dispose of it following local legislation. In case of ga ecape or of entry into waterways, soil or drains, inform the responsible authorities if required. Suitable material for taking up : dry and inert absorbing material (e.g. vermiculite, sand, earth).
Methods and material for containment and cleaning up : suitable material for taking up : dry and inert absorbing material (e.g. vermiculite, sand, earth). Wash with plenty of water.
Handling and storage
Precautions for safe handling: Avoid contact with skin contact and eyes, inhalation of vapours and mists. Don't use empty container before they have been cleaned. Before making transfer operations assure that there aren't any incompatible material residus in the containers. Contamined clothing should be changed before entering eating areas. Do not eat or drink while working.
Condition for safe storage, including any incomptaibilites : store in a tightly closed container in a cool, dry, well ventilated area.
Incompatible materials : None in particular
Instructions as regards storage premises : adequately ventilated premises.
Specific end use(s) Recommendation : storage temperature <25°C , Industrial sector specific solutions : None in particular
