Guidance on Safe Use

First-aid measures

- 4.1 Description of first aid measures

- General information

Instantly remove any clothing soiled by the product.

Symptoms of poisoning may even occur after several hours; therefore medical observation for at least 48

hours after the accident.

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

- After skin contact Instantly rinse with water.

- After eye contact

Rinse opened eye for several minutes (10 - 15) under running water. Then consult doctor.

Use eye protection.

- After swallowing Instantly call for doctor.

Fire-fighting measures

- 5.1 Extinguishing media

- Suitable extinguishing agents

CO2, extinguishing powder or water jet. Fight larger fires with water jet or alcohol-resistant foam.

For safety reasons unsuitable extinguishing agents Do not use a heavy water stream.

- 5.2 Special hazards arising from the substance or mixture

Vapours heavier than air.

Vapors are heavier than air and spread along ground (floors).

- 5.3 Advice for firefighters

- Protective equipment:

Wear self-contained breathing apparatus.

Do not inhale explosion gases or combustion gases.

Wear full protective suit.

- Additional information

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

Combustible.

Accidental release measures

- 6.1 Personal precautions, protective equipment and emergency procedures

Wear protective equipment (described in section 8). Keep unprotected persons away.

Do not inhale fumes/aerosol.

Avoid contact with substance.

Use only explosion-protected devices and tools free of spark use.

Ignition sources, sparking and flames avoid.

Evacuate the danger area, observe emergency procedures, consult an expert.

- 6.2 Environmental precautions:

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

Prevent material from reaching sewage system, holes and cellars.

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

- 6.3 Methods and material for containment and cleaning up:

Absorb with liquid-binding material (sand, diatomite, acid binders, universal binders).

Dispose of contaminated material as waste according to item 13.

Ensure adequate ventilation.

Send for recovery or disposal in suitable containers.

Exposure controls / personal protection

- 8.1 Control parameters

- Components with limit values that require monitoring at the workplace:

75-05-8 acetonitrile

WEL (Great Britain) Short-term value: 102 mg/m³, 60 ppm

Long-term value: 68 mg/m³, 40 ppm

IOELV (European Union) Long-term value: 70 mg/m³, 40 ppm

Skin

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

- 8.2 Exposure controls

- Personal protective equipment

- General protective and hygienic measures

The usual precautionary measures should be adhered to general rules for handling chemicals.

Keep away from foodstuffs, beverages and food.

Take off immediately all contaminated clothing

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

Avoid contact with the eyes and skin.

Do not eat, drink or smoke while working.

Do not inhale fumes

- Breathing equipment: Filter A (acc. to EN 141) for organic vapours and gases; boiling piont > 65 °C

- Recommended filter device for short term use:

The entrepreneur has to ensure that maintenance, cleaning and testing of respiratory protective devices are carried out according to the instructions of the manufacturer. These measures have to be properly

documented.

- Protection of hands:

Protective gloves (EN 374).

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.

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

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.

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 trough time has to be found out by the manufacturer of the protective gloves and has to be observed.

The times listed are suggested by measurements taken at 22 degree C and constant contact. Temperatures raised by warmed substances, body heat, etc. and a weakening of the effective layer thickness caused by expansion can lead to a significantly shorter breakthrough time.

In case of doubt contact the gloves' manufacturer.

A 1.5-times increase / decrease in the layer thickness doubles / halves the breakthrough time. This data only applies to the pure substance. Transferred to mixtures of substances, these figures should only be taken as an aid to orientation.

- Remark:

This recommendation applies only to the product stated in the safety data sheet. When dissolving in or mixing this substance with other substances and under conditions deviating from those stated in EN 374, please contact the supplier of CE –approved gloves.

- Eye protection:

Tightly sealed safety glasses.

- Body protection:

Protective work clothing.

Protective clothing should be selected specifically for the working place, depending on concentration and quantity of the hazardous substances handeld. The resistance of the protective clothing to chemicals should be ascertained with the respective supplier.
