First-aid measures
Description of first aid measures
Pay attention to self-protection.
Remove victims from hazardous area. Immediately remove soiled or soaked clothing and remove it to a safe distance. Keep victim warm, in a stabilized position and covered.
Do not leave victims unattended.
If the casualty is unconscious: Place the victim in the recovery position.
Skin contact
Wash off affected area immediately with plenty of water.
Continue decontamination with polyethylene glycol 400 after initial rinsing with water and then wash with water and soap.
If symptoms persist, consult a physician for treatment.
Eye contact
With eye held open, thoroughly rinse immediately with plenty of water for at least 10 minutes.
Inform emergency physician immediately. (key term: caustic eye burn)
Ingestion
Rinse out mouth.
Immediately give large quantities of water to drink.
Inform emergency physician immediately.
Indication of any immediate medical attention and special treatment needed
The initial focus is only on the local action, characterized by quickly progressing deep tissue damage.
Coughing is a symptom of respiratory tract after inhalation of dusts or smoke from caustic solids.
In the eye, caustic dusts or smoke cause, depending on the intensity of exposure, severe irritation, destruction, and ablation of the epithelium of the conjunctiva and cornea, corneal clouding, edema and ulcerations.
Danger! Possible loss of eyesight!
Superficial irritations and damage up to ulcerations and scarring develop on the skin.
Fire-fighting measures
Suitable extinguishing media
dry powder, dry sand
Unsuitable extinguishing media
water, high volume water jet, water spray, foam
Special hazards arising from the substance or mixture
In case of fire cool endangered containers with water.
In the case of fire, the following hazardous smoke fumes may be produced:
Carbon oxides
Special protective equipment for fire-fighters
wear a self contained respiratory apparatus
Wear suitable protective clothing.
Advice for firefighters
Water used to extinguish fire should not enter drainage systems, soil, or stretches of water Ensure there are sufficient retaining facilities for water used to extinguish fire. Contaminated fire-extinguishing water must be disposed of in accordance with the regulations issued by the appropriate local authorities.
Fire residues should be disposed of in accordance with the regulations.
Accidental release measures
Personal precautions, protective equipment and emergency procedures
Avoid dust formation.
Keep away from sources of ignition - No smoking.
Wear personal protective equipment
Environmental precautions
Do not allow substance to enter soil, bodies of water or sewage canals.
Methods and material for containment and cleaning up
Cover with
dry sand
Use mechanical handling equipment.
To be disposed of in compliance with existing regulations.
Confer with the producer.
Handling and storage
Handling
Precautions for safe handling
Under inert gas (argon, nitrogen).
Avoid dust formation.
Observe the rules usually applicable when handling chemicals.

Disposal considerations
Product
Before disposal consult producer.
With respect to local regulations, e.g.
dispose of to suitable waste incineration plant.
No waste key number as per the European Waste Types List can be assigned to this product, since such classification is based on the (as yet undetermined) use to which the product is put by the consumer.
The waste key number must be determined as per the European Waste Types List (decision on EU Waste Types List 2000/532/EC) in cooperation with the disposal firm / producing firm / official authority.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
