8 Exposure controls/personal protection
· Exposure controls
· Personal protective equipment:
· General protective and hygienic measures:
Keep away from foodstuffs, beverages and feed. Immediately
remove all soiled and contaminated clothing. Wash hands
before breaks and at the end of work.
Store protective clothing separately.
Avoid contact with the eyes and skin.
· Breathing equipment:
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.
· Protection of hands:
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.
· Eye protection: Wear chemical goggles or face shield.
· Body protection: Protective work clothing
