• General protective and hygienic measures: Keep away from foodstuffs, beverages and feed.

Personal protective equipment

Eye and face protection

Tightly sealed goggles

Skin protection

As below\

Body protection

• Protective gloves
• 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.

Respiratory protection

• In case of brief exposure or low pollution use respiratory filter device. In case of intensive or longer exposure use
• respiratory protective device that is independent of circulating air.
