Methods and materials for containment and clean up

• Absorb with liquid-binding material (sand, diatomite, acid binders, universal binders, sawdust).
• Dispose contaminated material as waste according to item 13.
• Ensure adequate ventilation

7. Handling and Storage

Precautions for safe handling

• Ensure good ventilation/exhaustion at the workplace.
• Open and handle receptacle with care.
• Prevent formation of aerosols.
• Keep respiratory protective device available.
• Information about protection against explosions and fires: Keep respiratory protective device available

Conditions for safe storage

• Store in a cool, well ventilated area, out of direct sunlight. Keep containers closed when not in use. Store in original container.
• Conditions for safe storage, including any incompatibilities
• Storage:
• Requirements to be met by storerooms and receptacles: No special requirements.
• Information about storage in one common storage facility: Not required.
• Further information about storage conditions: Keep receptacle tightly sealed.
• Specific end use(s) No further relevant information available.

8. Exposure Controls / Personal Protection

Exposure Standards

Engineering controls

• Maintain concentration below recommended exposure limit. Local exhaust ventilation system may be required.
• · 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.

Personal protective equipment

Eye and face protection

Goggles recommended during refilling.

Skin protection

The glove material has to be impermeable and resistant to the product/ the substance/ the preparation

Body protection

• 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.

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.
