Do not allow to enter sewers/ surface or ground water.
Inform respective authorities in case of seepage into water course or sewage system.
Methods and material for containment and cleaning up:
Dyke up, pump or absorb liquid components with an inert liquid-binding material.
Ensure adequate ventilation.
Do not use sawdust
Dispose of the material collected according to regulations.
Dispose contaminated material as waste according to item 13.
Reference to other sections
See Section 7 for information on safe handling.
See Section 8 for information on personal protection equipment.
See Section 13 for disposal information.
Handling and storage

Exposure controls / personal protection
Additional information about design of technical facilities: No further data; see item 7.
Control parameters
∙ Ingredients with limit values that require monitoring at the workplace: Not required.
∙ Additional information: The lists valid during the making were used as basis.
Exposure controls
∙ Personal protective equipment:
∙ General protective and hygienic measures:
The usual precautionary measures are to be adhered to when handling chemicals.
Avoid contact with the eyes and skin.
Immediately remove all soiled and contaminated clothing
Wash hands before breaks and at the end of work.
Keep away from foodstuffs, beverages and feed.
∙ Respiratory protection:
Where risk assessment shows air-purifying respirators are appropriate use a mask filter with multi-purpose
combination (US) or type ABEK according standard EN 14387) respirator cartridges
∙ Protection of hands:
Protective gloves
The protective gloves to be used must comply with specifications of CE directive 89/686/EEC and he resultant
standard EN 374.
Selection of the glove material on consideration of the penetration times, rates of diffusion and the degradation
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.
∙ 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.
∙ Eye protection:
Tightly sealed goggles
Face protection
∙ Body protection:
Boots
Apron
