8. Exposure Controls / Personal Protection

Exposure Standards

Engineering controls

No further data; see section 7

Personal protective equipment

Eye and face protection

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

Skin protection

• Keep away from foodstuffs, beverages, and feed.
• Immediately remove all soiled and contaminated clothing.
• Wash hands before breaks and at the end of work.

Body protection

• Protective gloves
• The glove material has to be impermeable and resistant to the product, the substance, or 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 therefore has to be checked prior to the application.
• Penetration time of glove material
• The exact breakthrough through time has to be found out by the manufacturer of the protective gloves and has to be
• observed

Respiratory protection

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

• Corrosive
• Irritant

12. Ecological Information

Ecotoxicity

· Aquatic toxicity: No further relevant information is available

Persistence and degradability

No further relevant information is available

Bioaccumulative potential

No further relevant information is available

Other adverse effects

• General notes:
• Water hazard class 2 (Self-assessment): hazardous for water
• Do not allow the product to reach groundwater, a watercourse, or a sewage system.
• Must not reach bodies of water or drainage ditches undiluted or unneutralized.
• Danger to drinking water if even small quantities leak into the ground.
• Also poisonous for fish and plankton in water bodies.
• Very toxic for aquatic organisms
• Rinsing off bigger amounts into drains or the aquatic environment may lead to increased pH-values. A high pH value harms aquatic organisms. In the dilution of the use-level, the pH value is considerably reduced so that after the use of the product, the aqueous waste, emptied into drains, is only low-water dangerous.
