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.

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.

Most important symptoms and effects, both acute and delayed:

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:

All extinguishing substances suitable.

Unsuitable extinguishing media:

Do not use a solid water stream as it may scatter and spread fire.

Special hazards arising from the substance or mixture:

Danger of decomposition under influence of heat.

In case of smoldering fire: nitric oxides, chlorine, carbon monoxide.

In the case of fire, the following hazardous smoke fumes may be produced: ammonia, nitric oxides, chlorine, carbon monoxide.

Special protective equipment for fire-fighters:

In the event of fire, wear self-contained breathing apparatus.

Full protective suit.

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.

Contaminated extinguishing water must be treated at a suitable disposal plant in accordance with waste management laws.

In case of fire, remove the endangered containers and bring to a safe place, if this can be done safely.

Fire residues should be disposed of in accordance with the regulations.

Keep out unprotected persons.

Accidental release measures

Personal precautions, protective equipment and emergency procedures:

Wear personal protective equipment.

Keep unauthorized persons away.

Avoid dust formation.

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:

Pick up mechanically.

Collect in suitable containers.

To absorb spilled substance an approved industrial vacuum cleaner is recommended.

If necessary, the spilled substance should be moistened.

Pack and label wastes like the pure substance.

Do not detach label from the delivery containers prior to disposal.

Dispose of absorbed material in accordance with the regulations.

Clean contaminated surface thoroughly.

Handling and storage

Handling:

Precautions for safe handling:

Use permissible in closed systems only. Handle and transfer product in closed systems only (gas displacement device).

Ensure that apparatus and pipelines are free from leaks. Do not ventilate into the open.

Dedicated loading/unloading stations required.

The product should only be handled by trained personnel.

Always close container tightly after removal of product.

Avoid residues of the product on the containers.

Avoid dust formation.

Avoid contact with skin, eyes and clothing.

Do not inhale dusts.

Take precautionary measures against static discharges.

Provide good ventilation or extraction.

Advice on protection against fire and explosion:

Normal measures for preventive fire protection.

Caution - electrostatic charge may occur.

Ensure there are sufficient retaining facilities for water used to extinguish fire.

Further information: VDI 2263 "Dust fires and dust explosions; dangers, evaluation, preventive measures."

Dust explosion class:

Dust explosion class ST 1.

Storage:

Conditions for safe storage, including any incompatibilities:

Store in the original receptacle, keeping this tightly sealed, under cool and dry conditions.

Further information:

Protect from sunlight, warmth and heat.

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.

In the event of internal transportation, already-opened containers are to be kept closed in order to avoid spillage.

Advice on common storage:

No special precautions required.

German storage class:

Combustible / non-combustible liquids and solids not assigned to other storage classes.
