路 Personal protective equipment:
路 General protective and hygienic measures:
Keep away from foodstuffs, beverages and feed.
Wash hands before breaks and at the end of work.
Store protective clothing separately.
Avoid contact with the eyes and skin.
路 Breathing equipment:
NIOSH approved respirators should be used if dust is present. A respiratory protection program
should be implemented if exposures exceed OSHA PELs.
路 Protection of hands:
Protective gloves recommended
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
路 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.
路 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.
