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.
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), Do not use full-force water jet in order to avoid dispersal and spread of the fire
Special hazards arising from the substance or mixture
Reacts violently with water and foam.
In the case of fire, the following hazardous smoke fumes may be produced: carbon monoxide, carbon dioxide.
organic products of decompositionIn case of fire-fighting with water or foam be aware of dangers of corrosion and of slipping.
Combustion residues must be disposed of properly.
Advice for firefighters
Contaminated extinguishing water must be treated at a suitable disposal plant in accordance with waste management laws.
Water used to extinguish fire should not enter drainage systems, soil or stretches of water.
In case of fire, remove the endangered containers and bring to a safe place, if this can be done safely.
Use water spray to cool unopened containers.
Fire residues should be disposed of in accordance with the regulations.
Pay attention to self-protection.
Keep out unprotected persons.
In case of fire: full protective suit and wear a self contained respiratory apparatus
Accidental release measures
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
Observe regulations on prevention of water pollution (check, dam up, cover up).
Do not allow entrance in sewage water, soil, stretches of water, drainage systems, surface water.
If the product contaminates rivers and lakes or drains inform respective authorities.
Methods and material for containment and cleaning up
Cover with
dry sand
Pick up mechanically and collect in a suitable container. Avoid formation of dust.
Clean contaminated surface thoroughly.
Pack and label wastes like the pure substance. Do not detach label from the delivery containers prior to disposal.
Disposal according to local authority regulations.
Suitable binder: dry sand
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.
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.
Storage under inert gas (nitrogen) recommended.
Suitable materials: polyethylene
Unsuitable materials: light metals and their alloys, Aluminium, Zinc
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.
