Guidance on Safe Use

First-aid measures

· General information

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

least 48 hours after the accident.

· After inhalation Supply fresh air; consult doctor in case of symptoms.

· After skin contact

Exposure controls / personal protection

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

· Components with limit values that require monitoring at the workplace: Not required.

· 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.

Take off immediately all contaminated clothing

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

Avoid contact with the eyes and skin.

· Breathing equipment:

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.

· Protection of hands:

Protective gloves.

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

preparation.

DR

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 trough 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: suitable clothing

Stability and reactivity

· Thermal decomposition / conditions to be avoided:

No decomposition if used according to specifications.

· Materials to be avoided:

· Dangerous reactions No dangerous reactions known

· Dangerous products of decomposition: No dangerous decomposition products known

Disposal considerations

· Product:

· Recommendation Must be specially treated under adherence to official regulations.

· Uncleaned packagings:

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