· After eye contact Rinse opened eye for several minutes under running water. Then consult doctor.

· After swallowing

Rinse out mouth and then drink plenty of water.

Induce vomiting and call for medical help.

Induce vomiting only if person affected is fully conscious.

Fire-fighting measures

· Suitable extinguishing agents Use fire fighting measures that suit the environment.

· For safety reasons unsuitable extinguishing agents none

· Special hazards caused by the material, its products of combustion or flue gases:

Formation of poisonous gases during heating or in fires.

Nitrogen oxides (NOx)

Carbon monoxide and carbon dioxide

Can form explosive vapour-air mixtures.

· Protective equipment: Wear self-contained breathing apparatus.

· Additional information

Cool endangered containers with water spray jet.

Dispose of fire debris and contaminated fire fighting water in accordance with official regulations.

Accidental release measures

· Person-related safety precautions:

Wear protective equipment. Keep unprotected persons away.

Ensure adequate ventilation.

Remove all ignition sources.

Do not breathe vapours.

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

Avoid skin and eye contact.

· Measures for environmental protection:

Do not allow product to reach sewage system or water bodies.

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

· Measures for cleaning/collecting:

Ensure adequate ventilation.

Handling and storage

· Handling

· Information for safe handling:

Ensure good ventilation/exhaustion at the workplace.

Use only in well ventilated areas.

Keep away from heat and direct sunlight.

Avoid splashes or spray in enclosed areas.

Avoid breathing vapours.

Avoid skin and eye contact.

· Information about protection against explosions and fires:

Highly volatile, flammable constituents are released during processing.

Flammable mixtures may be formed in empty containers.

Exposure controls / personal protection

· Additional information about design of technical systems: No further data; see item 7.

· Components with critical values that require monitoring at the workplace:

The product does not contain any relevant quantities of materials with critical values that have to be

monitored at the workplace.

· Additional information: The lists that were valid during the compilation were used as basis.

· Personal protective equipment

· General protective and hygienic measures

Keep away from foodstuffs, beverages and food.

Instantly remove any contaminated garments.

Store protective clothing separately.

Do not inhale gases / fumes / aerosols.

Avoid contact with the eyes and skin.

Do not eat, drink or smoke while working.

Do not carry cleaning cloths impregnated with the product in trouser pockets.

Clean skin thoroughly immediately after handling the product.

· Breathing equipment:

Filter B

In case of brief exposure or low pollution use breathing filter apparatus. In case of intensive or longer

exposure use breathing apparatus that is independent of circulating air.

· Recommended filter device for short term use: Combination filter K-P3

· Protection of hands:

Protective gloves

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

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

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

Due to missing tests no recommendation to the glove material can be given for the product/ the preparation/

the chemical mixture.

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

degradation.

· Material of gloves

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. As the product is a preparation of several substances, the

resistance of the glove material can not be calculated in advance and has therefore to be checked prior to the

application.

· Penetration time of glove material

The exact break through time has to be found out by the manufacturer of the protective gloves and has to be

observed.

· Eye protection: Tightly sealed safety glasses

· Body protection: Protective work clothing

Stability and reactivity

· Thermal decomposition / conditions to be avoided: Explosive thermal decomposition

· Materials to be avoided:

Strong oxidizing agents

Heavy metals

Heavy metal compounds

· Dangerous reactions

Metals and metaloxides catalyse explosive decomposition.

Flammable vapour-air mixtures may develop.

Forms explosive gases / fumes

· Dangerous products of decomposition:

Poisonous gases/vapours

Nitrogen oxides (NOx)

Carbon monoxide and carbon dioxide

Disposal considerations

· Recommendation

Must not be disposed of together with household garbage. Do not allow product to reach sewage system.

Disposal must be made according to official regulations.

· European waste catalogue

Waste disposal key numbers from EWC have to be assigned depending on origin and processing

· Uncleaned packagings:

· Recommendation: Disposal must be made according to official regulations.

· Recommended cleaning agent: Water, if necessary with cleaning agent.
