Guidance on Safe Use

First-aid measures

General information:

Immediately remove any clothing contaminated by the product.

Take affected persons out of danger area and instruct to lie down.

Remove breathing apparatus only after soiled clothing has been completely removed.

In case of irregular breathing or respiratory arrest provide artificial respiration.

Do not leave affected persons unsupervised.

Personal protection for the person providing first aid.

After inhalation:

Supply fresh air. If required, provide artificial respiration. Keep patient warm. Consult doctor if symptoms

persist.

Do not use mouth to mouth or mouth to nose resuscitation.

In case of unconsciousness bring patient into stable side position for transport.

· After skin contact:

Wash with soap and water.

Consult doctor in case of symptoms.

· After eye contact:

Remove contact lenses, if present and easy to do.

Rinse opened eye for several minutes under running water. If symptoms persist, consult doctor.

· After swallowing:

Rinse out mouth and then drink plenty of water.

Instantly call for doctor.

Fire-fighting measures

Extinguishing media

· Suitable extinguishing agents

Carbon dioxide (CO₂), extinguishing powder or water spray/fog. Fight larger fires with water spray/fog or

alcohol-resistant foam.

· For safety reasons unsuitable extinguishing agents Water with a full water jet.

Special hazards arising from the substance or mixture

Risk of dust explosion if enriched with fine dust in presence of air.

Nitrogen oxides (NOx)

Hydrogen cyanide (HCN)

Carbon monoxide (CO) and Carbon dioxide (CO₂)

Danger of toxic pyrolysis products

Advice for firefighters

· Protective equipment: Wear self-contained breathing apparatus.

· Additional information Collect contaminated fire fighting water separately. It must not enter drains.

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Ensure adequate ventilation.

Remove all ignition sources.

Avoid causing dust.

Do not breathe dust.

Use breathing protection against the effects of fumes/dust/aerosol.

Avoid contact with skin and eyes.

Wear protective equipment. Keep unprotected persons away.

Environmental precautions:

Damp down dust with water spray jet.

Do not allow to enter drainage system, surface or ground water.

Inform respective authorities in case product reaches water or sewage system.

Methods and material for containment and cleaning up:

Ensure adequate ventilation.

Collect mechanically.

Send for recovery or disposal in suitable containers.

Dispose of the material collected according to regulations.

Handling and storage

Precautions for safe handling

Ensure good ventilation/exhaustion at the workplace.

Prevent formation of dust.

Any deposit of dust which cannot be avoided must be removed regularly.

If dust/smoke is developed, avoid breathing dust/smoke.

Avoid contact with eyes.

Avoid prolonged or repeated skin contact.

· Information about protection against explosions and fires:

Protect against electrostatic charges.

Keep ignition sources away - Do not smoke.

Fine dust particles can form explosive/ignitable mixture with air.

Protect from heat.

Exposure controls / personal protection

Exposure controls / · Personal protective equipment

· General protective and hygienic measures

Keep away from foodstuffs, beverages and food.

Instantly remove any contaminated garments.

Do not eat, drink or smoke while working.

Do not breathe dust.

Avoid contact with the eyes.

Avoid close or long term contact with the skin.

Wash hands during breaks and at the end of the work.

Use skin protection cream for preventive skin protection.

· Breathing equipment: Dust proof mask - particle filter mask

· Recommended filter device for short term use: Partikelfilter EN 143 Type P2 or P3

· Protection of hands:

Protective gloves

The glove material has to be impermeable and resistant to the product/ the substance/ the preparation.

Selection of the glove material on consideration of the penetration times, rates of diffusion and the

degradation.

Check the permeability prior to each renewed use of the glove.

To avoid skin problems reduce the wearing of gloves to the required minimum.

· Material of gloves

Nitrile rubber - NBR

Recommended thickness of the material: ≥ 0.11 mm

Poly vinyl chloride - PVC

Polychloroprene

The selection of the suitable gloves does not only depend on the material, but also on further marks of quality

and varies from manufacturer to manufacturer.

· Penetration time of glove material Protective gloves should be replaced at first signs of wear.

· Eye protection: Tightly sealed safety glasses

· Body protection:

Protective work clothing

Body protection must be chosen depending on activity and possible exposure.
