Exposure Standards

Engineering controls

• No further data; see section 7.
• 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.
• Avoid contact with the eyes and skin.

Personal protective equipment

Eye and face protection

• Tightly sealed goggles.
• 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.
• Avoid contact with the eyes and skin.

Skin 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.
• 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.
