· 8.2 Exposure controls

· Personal protective equipment

· General protective and hygienic measures

Do not eat, drink or smoke while working.

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

Take off immediately all contaminated clothing

Avoid contact with the eyes and skin.

· Breathing equipment:

Use a breathing protection if high concentrations are present.

Short term filter device:

Filter A/P2.

· 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

· Material of gloves

PVC 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.
