Exposure controls

∙ Personal protective equipment:

∙ General protective and hygienic measures:

The usual precautionary measures are to be adhered to when handling chemicals.

Avoid contact with the eyes and skin.

Immediately remove all soiled and contaminated clothing

Wash hands before breaks and at the end of work.

Keep away from foodstuffs, beverages and feed.

∙ Respiratory protection:

Where risk assessment shows air-purifying respirators are appropriate use a mask filter with multi-purpose

combination (US) or type ABEK according standard EN 14387) respirator cartridges

∙ Protection of hands:

Protective gloves

The protective gloves to be used must comply with specifications of CE directive 89/686/EEC and he resultant

standard EN 374.

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

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.

∙ 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.

∙ 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 goggles

Face protection

∙ Body protection:

Boots

Apron
