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.


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)


Rinse mouth.

Immediately give large quantities of water to drink.

Inform emergency physician immediately.

Most important symptoms and effects, both acute and delayed:


Causes burns.


Strongly irritating to corrosive.

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

Extinguishing media:

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:

Hazard-determining flue gases might develop in case of fire:

- Carbon monoxide

- Carbon dioxide (CO2)

- Nitrogen oxides (NOx)

- Organic products of decomposition

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

Personal precautions, protective equipment and emergency procedures:

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 and collect in a suitable container.

Avoid formation of dust.

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

If necessary, the spilled substance should be moistened.

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.

Handling and storage

Precautions for safe handling:

Avoid dust formation.

Do not breathe dust.

Avoid contact with skin, eyes and clothing.

Avoid residues of the product on the containers.

Conditions for safe storage, including any incompatibilities:

Advice on protection against fire and explosion:

Normal measures for preventive fire protection.

Take precautionary measures against static discharges.

Keep away from flames / sparks, no smoking.

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."


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

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.

German storage class:

8B - Non-combustible, corrosive hazardous materials.

Personal protective equipment:

Respiratory protection:

When handling for a short time:

If dust occurs: dust mask with P1 particle filter.

In the event of prolonged exposure during handling:

In the case of respirable dust, use self-contained breathing apparatus.

Note time limit for wearing respiratory protective equipment.

Hand protection:

Applies to handling for brief periods or of small amounts:

Glove material: Nitrile, for example, Dermatril 740, Kächele-Cama Latex GmbH (KCL), Germany

Material thickness: 0.11 mm

Method: DIN EN 374.

Applies to handling for longer periods or of large amounts:

Glove material: Nitrile/Chloroprene, for example, Nitopren 717, Kächele-Cama Latex GmbH (KCL), Germany

Material thickness: 0.65 mm

Method: DIN EN 374

Selection of protective gloves to meet the requirements of specific workplaces.

Suitability for specific workplaces should be clarified with protective glove manufacturers.

The information is based on our own tests, references from the literature and information from glove manufacturers, or derived by analogy with similar materials.

Remember that the useful time per day of a chemical protection glove may be much shorter than the permeation time determined according to EN 374 due to the many different influential factors involved (e.g. temperature).

Eye protection:

Safety glasses with side-shields conforming to EN166


If dust occurs: basket-shaped glasses.

Skin and body protection:

Select materials and equipment for physical protection depending on the concentration and volume of hazardous substances and the workplace involved.
