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 stabilizedposition and covered.
Do not leave victims unattended.
If the casualty is unconscious: Place the victim in the recovery position.

Inhalation
Potential for exposure by inhalation if dusts or smoke are generated.
Move victims into fresh air.
With labored breathing: Provide with oxygen. Consult a doctor.
If the casualty is not breathing: Perform mouth-to-mouth resuscitation, notify emergency physician immediately.

Skin contact
Wash off affected area immediately with plenty of water for at least 15 minutes.
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.
Consult an ophthalmologist immediately if the symptoms persist.
When dealing with caustic substances, notify emergency physician immediately (key words: burns in eye).

Ingestion
Rinse mouth.
Immediately give large quantities of water to drink.
Obtain medical attention.
When dealing with caustic substances, notify emergency physician immediately.

Most important symptoms and effects, both acute and delayed
Symptoms
Irritation of skin and mucous membranes
Causes burns.
daze,
Headache, vertigo, somnolence (sleepiness), nausea.
Health injuries may be delayed.
Hazards
Strongly irritating to corrosive.Harmful in contact with skin and if swallowed. Vapours may cause drowsiness and dizziness.

Indication of any immediate medical attention and special treatment needed
The initial focus is only on the local action, possibly characterized by a progressive tissue irritation; caustic substances result in quickly progressing deep
tissue damage.
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.
After accidental absorption in the body, the pathology and clinical findings are dependent on the kinetics of the substance (quantity of absorbed substance,
the absorption time, and the effectiveness of early elimination measures (first aid)/ excretion - metabolism).
A specific action of the substance is unknown.

Fire-fighting measures

Extinguishing media
Suitable extinguishing media:
dry sand
Dry powder
alcohol stable extinguishing foam

Unsuitable extinguishing media:
Water
Foam
Halons
Carbon dioxide (CO2)

Special hazards arising from the substance or mixture
Do not extinguish fires at the leak point since this can result in an uncontrolled blow-back combustion.
In case of fire-fighting with water or foam be aware of dangers of corrosion and of slipping.
Upon contact with water: violent reaction!
Do not use a solid water stream as it may scatter and spread fire.

Advice for firefighters
Water for fire fighting must not be introduced in the sewer system, subsoil, or surface waters. Assure that there are sufficient fire water retaining facilities
Contaminated fire fighting water must be disposed of in conformity with the regulations of the local authorities.
Fire residues should be disposed of in accordance with the regulations.
In case of fire: full protective suit and wear a self contained respiratory apparatus

Accidental release measures

Personal precautions, protective equipment and emergency procedures
Avoid dust formation.
Keep away from sources of ignition - No smoking.
Keep unauthorized persons away.

Environmental precautions
Dam with sand or earth
Do not allow to reach the sewage system, the ground or natural water bodies.

Methods and material for containment and cleaning up
Use mechanical handling equipment.
Suitable binder: lime, soda ash, dry sand

Additional advice
Protect against water.Risk of spontaneous ignition on entry of airEvacuate personnel to safe areas.Remove all sources of ignition.Sweep up to prevent slipping hazard.Avoid dust formation.

Reference to other sections
Wear personal protective equipment.

Handling and storage

Precautions for safe handling
Decant and handle product in separate areas only, e.g. use glove boxes, cabinets with differential pressure switch etc.
Ensure that apparatus and pipelines are free from leaks. Do not ventilate into the open.
Dedicated loading/unloading stations required.
Handle under inert gas
Take precautionary measures against static discharges.

Conditions for safe storage, including any incompatibilities
Advice on protection against fire and explosion
Take precautionary measures against static discharges.
Keep away from sources of ignition - No smoking.
No sparking tools should be used.
Avoid dust formation.
If dusts develop, explosive dust/air mixtures may form.

Storage
Store in the original receptacle, keeping this tightly sealed, under cool and dry conditions.
Protect from warming.
Avoid humidity and water.
Under inert gas (nitrogen).
Suitable materials polyethylene
Unsuitable materials light metals and their alloys

Further information
In order to ensure due transportation, make certain that stacks are of the correct height, containers are securely fastened so as not to fall off, and labelled according to the regulations.

Advice on common storage
Observe prohibition against storing together!
